Statistics for card packs are a means of observing the rarity drop rates for cards from card packs, determining the opportunity cost of whether a player should continue to buy or not buy packs.

NB: For inclusion into this article, studies recording the rarity drops of card packs should have a reasonably large sample size and should have a citable reference from a reputable source.

Notes[edit | edit source]

  • All card packs guarantee a card of Rare or better rarity, among the 5 cards opened.[1] This means every card pack will guarantee having at least one card of Rare/Epic/Legendary rarity, or in other words, all 5 cards will never be all of Common rarity.[2]
  • All types of card pack have the same chances at rarities and golden cards.[3][4][5]
  • Opening 100 packs from an expansion set is roughly equivalent to obtaining 75% of the cards in that set.[6]
    • 100 packs is approximately (98/98) Commons, (64/72) Rares, (20/54) Epics, and (4.5/20) Legendaries (taking Mean Streets of Gadgetzan as the example set).[7]
  • According to the meta-study data in this article from 2015, the average number of packs to open before receiving another Legendary card is 18.
  • Cards are decided during the opening of packs, not during the moment of purchase.[8]
    • A case has been made for "predetermined rarities" when opening packs "again".[9] This probably means that Hearthstone uses some method of seeding that allows it to determine the rarities of a player's future cards well in advance, and snapshots of the seeding progress are cached periodically server-side as a back-up mechanism in case of a system or database failure, as is what happened in China.
  • A true Hearthstone pack opening simulator cannot be created unless the source code is revealed. (See Discussion)
    • However, using the data showing the probability percentages of opening cards belonging to each rarity type, a user-generated "pack opening" simulator can be created. Employing Monte Carlo repeated simulation of such pack openings can yield information as to the average number of "missing" and "extra" cards a player may receive from opening "n" packs. Information as to the amount of dust obtained from disenchanting all "extra" cards obtained from such packs can also be obtained.
    • Other simulators may base their simulation on guesses as to how individual cards are selected to be opened from the card pool. The raw data obtained from this article can be used to either debunk or verify such hypothetical user-generated pack opening simulators.
  • As seen with the Tri-class card opening bug on December 1, 2016, in which Tri-class cards had a higher than normal chance of appearing in packs, there appears to be a card-opening variable based on "Classes".
  • China is, by law, requiring games which feature random drops purchasable by money, to publicly release the drop rates/statistics for those random drops, effective May 1, 2017. This includes Hearthstone.[10]
Blizzard complied with this law on April 2, 2017, by making a post to their Chinese forums.[11][12] The officially announced drop rates are:
  • RARE - At least 1 rare or better in each pack.
  • EPIC - Average of 1 every 5 packs.
  • LEGENDARY - Average of 1 every 20 packs.
Changes to pack opening logic, starting with Knights of the Frozen Throne (2017-06-22).
  • On June 22nd, 2017, Blizzard announced in a blog post several changes in pack openings that would take effect when the next expansion, Knights of the Frozen Throne, released on August 10th, 2017. The changes were described to affect packs of all future expansions:
    • When opening a new Legendary, it will always be a Legendary you do not own yet, unless you already own all Legendaries from that set. This mechanism does not distinguish between normal and golden cards.
Example: You own a golden Ysera. You will not find any Ysera (golden or non-golden) in any future Classic pack, until you own at least one copy of all Legendaries from the Classic set. After that, you may find another Ysera, which may or may not be golden.
  • A card pack will never include more copies of a single card than what may be used in a deck. In other words, there will never be three or more copies of a single Common, Rare, or Epic card, though you might still find two copies of a card that you already own one or more copies of. Once you have all Legendaries from a set, this same guarantee should also ensure that you do not get more than one copy of the same Legendary in a single pack.
  • When opening packs from a new set, at least one Legendary is now guaranteed within the first 10 packs. This is most likely achieved by initializing the Pity Timer to 30 for each new set.
The first two changes should not include the overall distribution of cards in packs; the last change will result in a small increase of the number of Legendaries. The relative increase will be higher for players opening few packs, and lower as a player opens more packs from the same set.[13]

Pity Timer[edit | edit source]

There is strong evidence that a "Pity Timer" exists, which defines a maximum number of packs that a player opens before guaranteeing the next Rare/Epic/Legendary card.[14][15] This Pity Timer counter is tracked individually for each store-bought expansion set, including Classic set.

  • An Epic card will be opened within 10 packs of the last opened Epic, for that set.[14]
  • A Legendary card will be opened within 40 packs of the last opened Legendary, for that set.

Pitytracker.com has also compiled their own card pack opening statistics for each expansion: pitytracker.com/insights.

Expected dust value[edit | edit source]

According to the below meta-study's data tabulated under the "Golden cards" section, the average card pack has a disenchanting value of 102.71 Arcane Dust.[16] Each card has an average disenchanting value of 20.54 Arcane Dust.

An in-depth statistical analysis of how much dust you can expect to get from a given pack opening is available here: https://www.reddit.com/r/hearthstone/comments/3bqvxx/have_you_ever_wondered_how_much_value_you_can_get/

Meta-study[edit | edit source]

The following numbers combine data from several other studies on this page. Since it has at times been suggested that the distribution of cards has changed over time or is different for different expansions, the numbers are shown per expansion. Note that all data collection has been done for each expansion when it was the most recent expansion, so there is for example no data available for card distribution in Classic packs that were openend after the release of Goblins vs Gnomes.

Currently included studies:

  • June 5, 2014: Steve Marinconz (1,000 Classic Packs)
  • August 2014: E. R. Kjellgren (11,359 Classic Packs)
  • February 12, 2015: Amaz (400 GvG Packs)
  • August 29, 2015: HearthSim (15,109 TGT Packs)
  • April 28, 2016: Kripparian (713 Old Gods Packs)
  • April 28, 2016: Amaz (413 Old Gods Packs)
  • December 1, 2016: Kripparian (896 Gadgetzan Packs, Before Tri-Class Bug Hotfix)
  • December 1-2, 2016: Kripparian (450 Gadgetzan Packs, After Tri-Class Bug Hotfix)
  • April 6, 2017: Kripparian (1,101 Journey to Un'Goro Packs)
  • April 8, 2017: N. Millar (1,256 Journey to Un'Goro Packs)

This produces a total sample size of 32,697 card packs, describing 163,485 cards in total.

  • September 13, 2017: Joe Tweak (380 Knights of the Frozen Throne Packs)

Rarity distribution[edit | edit source]

This table shows the likelihood of any single card being of a given rarity. The differences in the percentages appear to be all within the boundaries of statistical variance. This suggests that, at least up to and including the Un'Goro expansion, there have been no changes in the distribution of cards per rarity.

Expansion Cards Card count Percentage of total
Common Rare Epic Legendary Common Rare Epic Legendary
Classic 61,795 44,146 14,083 2,823 743 71.44% 22.79% 4.57% 1.20%
Goblins vs Gnomes * 2,000 1,419 462 97 22 70.95% 23.10% 4.85% 1.10%
The Grand Tournament 75,545 54,271 17,276 3,232 766 71.84% 22.87% 4.28% 1.01%
Whispers of the Old Gods 5,630 4,030 1,284 56 60 71.58% 22.81% 4.55% 1.07%
Mean Streets of Gadgetzan 6,730 4,805 1,556 299 70 71.40% 23.12% 4.44% 1.04%
Journey to Un'Goro 11,785 8,419 2,694 538 134 71.44% 22.86% 4.57% 1.14%
Knights of the Frozen Throne 1,900 1,361 441 80 18 71.63% 23.21% 4.21% 0.95%
Total for all expansions 163,485 117,090 37,355 7,245 1,795 71.62% 22.85% 4.43% 1.10%

* Note that the sample size for Goblins vs Gnomes & Knights of the Frozen Throne are probably too small to be statistically relevant.

Due to how cards are generated (with the guarantee of at least one Rare or better in any pack, plus the existence of a "Pity timer" for Epic and Legendary cards), the chance of finding at least one card of any given rarity can not simply mathematically be computed from the numbers above. However, for all pack openings since the TGT expansion the card rarities in any individual pack have been recorded. With these data, it is possible to determine the chances for these events:

Expansion Packs Packs with at least one Probability of at least one
Common Rare Epic Legendary Common Rare Epic Legendary
The Grand Tournament 15,109 15,106 14,480 3,073 760 99.98% 95.84% 20.34% 5.03%
Whispers of the Old Gods 1,126 1,126 1,067 241 60 100.00% 94.76% 21.40% 5.33%
Mean Streets of Gadgetzan 1,346 1,346 1,284 286 70 100.00% 95.39% 21.25% 5.20%
Journey to Un'Goro 2,357 2,355 2,241 500 132 99.92% 95.08% 21.21% 5.60%
Knights of the Frozen Throne No data available yet
Total for all expansions 19,938 19,933 19,072 4,100 1,022 99.97% 95.66% 20.56% 5.13%

Golden cards[edit | edit source]

The data from Marinconz does not include details of regular vs. golden opened in the packs. However, all other studies did include this data. After excluding the 5,000 cards from Marinconz' study, this results in the following probabilities of finding regular or golden cards of any rarity when opening packs. (For readability, the totals and the percentages are split over two separate tables):

Expansion Cards Number of regular Number of golden
Total Common Rare Epic Legendary Total Common Rare Epic Legendary

Disregarding the data from GvG (which is statistically irrelevant because of the small sample size), it appears that the chance of receiving a golden common card has been slightly increased as of the Old Gods expansion, while simultaneously lowering the chance of a regular common card. In other words, the chance of a common is unchanged, but any common card generated has an increased chance to be golden.


A different way to look at the data is to compute, for any given rarity, the ratio of regular versus golden cards. This is shown in the next table:

Expansion Cards Percentage golden Probability golden
Common Rare Epic Legendary Common Rare Epic Legendary
Classic 56,795 2.06% 6.03% 6.71% 9.29% 1 in 48.6 1 in 16.6 1 in 14.9 1 in 10.8
Goblins vs Gnomes 2,000 2.04% 6.49% 5.15% 9.09% 1 in 48.9 1 in 15.4 1 in 19.4 1 in 11.0
The Grand Tournament 75,545 2.06% 5.54% 4.52% 7.31% 1 in 48.5 1 in 18.1 1 in 22.1 1 in 13.7
Whispers of the Old Gods 5,630 2.26% 5.84% 5.86% 10.00% 1 in 44.3 1 in 17.1 1 in 17.1 1 in 10.0
Mean Streets of Gadgetzan 6,730 2.31% 5.91% 5.69% 11.43% 1 in 43.3 1 in 16.9 1 in 17.6 1 in 8.8
Journey to Un'Goro 11,785 2.17% 6.61% 5.95% 8.96% 1 in 46.0 1 in 15.1 1 in 16.8 1 in 11.2
Knights of the Frozen Throne 1,900 2.10% 6.78% 6.67% 12.50% 1 in 47.6 1 in 14.7 1 in 15.0 1 in 8
Total for all expansions 158,485 2.09% 5.83% 5.55% 8.50% 1 in 47.9 1 in 17.1 1 in 18.0 1 in 11.8

This data again shows the increased chance of a Common card being golden since the Old Gods expansion. The seemingly erratic changes in the chance of a Legendary card being golden are probably a result of the relatively low amount of legendaries in the data, making the data statistically less trustworthy. However, it cannot be ruled out that the rules for generating a Legendary as golden or regular have been changed by Blizzard.

Class distribution[edit | edit source]

Only a single data set (the HearthSim data) tracked the class of the cards openend in addition to their rarity. Fortunately, this data set by itself is large enough for statistical relevant. However, this obviously means that there is no way to verify whether there have been changes in distribution across the classes over time, and whether the same pattern applies for expansions other than TGT.

The table below shows, per rarity and by class, the average number of times each card was opened. (Example: A total of 3,227 Common Mage cards were openened; since the TGT expansion includes 3 Common Mage cards the average number per card is 1,075.67).

Class Common Rare Epic Legendary
Druid 1,106.00 486.33 123.50 28.00
Hunter 1,092.67 498.00 118.00 38.00
Mage 1,075.67 493.00 127.50 32.00
Paladin 1,082.67 486.67 113.50 51.00
Priest 1,118.33 475.67 117.50 28.00
Rogue 1,116.33 491.33 126.00 28.00
Shaman 1,134.00 469.00 125.50 30.00
Warlock 1,098.67 482.33 122.00 47.00
Warrior 1,114.67 472.33 116.50 34.00
Neutral 1,111.55 468.00 116.89 41.20

The variations in the numbers are all within the boundaries of expected statistical variance. This suggests that the pack opening algorithm does not favor any specific class, nor neutral cards over class-speecific cards. However, that does not mean that there is an equal chance of finding any class or neutral; it means that any card of a given rarity is equally likely to be found. Since TGT (like all other expansions) has more neutral cards than it has class-specific cards, the chance of getting a neutral card is still higher.

Data[edit | edit source]

June 5, 2014: Steve Marinconz[edit | edit source]

On June 5th 2014 Steve Marinconz published the following results in an article on Kotaku.com.[17] The data was collected by aggregating the results of numerous card pack opening videos found online, with a total of 1,000 packs. The study used only videos filmed in the last two months.

Common Rare Epic Legendary
Count per 1,000 packs 3,565 1,155 215 65
Percentage of total 71.30% 23.10% 4.30% 1.30%
Probability of at least 1 per pack * 99.81% * 73.11% * 19.73% * 6.33% *

* NOTE: The data in this row is as published in the article, but appears to be incorrect. According to these numbers, the chance of finding at least one Rare or better card in a pack is (73.11 + 19.73 + 6.33) = 99.17%, which is inconsistent with the guarantee of at least one Rare or better card. Apparently Marinconz computed these figures from the "Percentage of total" chances, based on the assumption of a flat distribution; however the "at least 1 Rare or better" guarantee invalidates this assumption and hence these numbers.

Based upon this data, Marinconz provided some interesting 'fun facts'. While these are based on the results of this single, relatively small study, the closeness of the study's results to those of other and larger studies suggests that the below information should still be relatively accurate, at least for the lower rarities.

  • The chances of getting a pack with any 5 legendary cards is one in a million
  • The chances of getting a pack with any 5 golden legendary cards is 1 in 3.2 billion
  • There's a 0.04% probability of getting 2 legendaries in a single pack
  • The probability of getting a pack with only one common card is about ~0.80%
  • There's a 16.26% probability of getting a pack with any golden card
  • Only 2.19% of common cards were golden, while 7.69% of legendaries were
  • The average $50 purchase of 40 packs will be worth about 3,600 Arcane Dust
  • The most common distribution was a '4100' - 4 commons and 1 rare - accounting for 61% of packs opened
  • The second most common distribution was a '3200' - 3 commons and 5 - accounting for 12.2% of packs opened

Unfortunately, Marinconz only posted aggregated data. Without data about individual packs, it is not possible to use this data for the "Probability of at least 1 per pack" table in the Meta-study. Also, since Steve didn't publish the exact number of golden cards, this study has also been excluded from any of the tables representing the chance of golden cards.

August 2014: E. R. Kjellgren[edit | edit source]

In August 2014 E. R. Kjellgren published an investigation into the rarities of cards found in card packs.[18] This was achieved by collecting user data from forums regarding the contents of 11,359 different card packs. The author notes that the investigation suffered from two main problems: the information collected was anonymous and its accuracy cannot be guaranteed; and the sample size, while adequate for the lower rarities, is still smaller than might be desired for the higher rarities. Kjellgren also divided rarities into golden and regular versions.

Based on the data below, the average card's dust value is 21.51 dust. The average pack's dust value is 107.54.

Percentage of total
Common Rare Epic Legendary
All 71.45% 22.76% 4.59% 1.19%
Regular 96.74% 69.98% 21.39% 4.28% 1.08%

Regular 54,942 39,746 12,148 2,433 615
Golden 1,853 835 780 175 63

The data showed golden cards to be on average around 30 times less common than regular cards. However, the proportion of golden and regular versions varied substantially by rarity. The author also notes that the sample sizes for the higher golden rarities are too small to be considered conclusive.

Common Rare Epic Legendary
Percentage golden 2.06% 6.03% 6.71% 9.29%
Rough probability 1 in 48.6 1 in 16.6 1 in 14.9 1 in 10.8

Unfortunately, Kjellgren only posted aggregated data. Without data about individual packs, it is not possible to use this data for the "Probability of at least 1 per pack" table in the Meta-study.

December 1, 2016: Kripparian opens 896 Gadgetzan Packs (Before Tri-Class Bug Hotfix)[edit | edit source]

Sources: YouTube - Raw data

  • The average card's dust value is 20.73 dust. The average pack's dust value is 103.63.
  • The "tri-class bug" was a time when, during the opening day for Mean Streets of Gadgetzan, tri-class cards had a higher chance of being opened from packs than other cards.[19]
  • It is unknown whether the YouTube video catches all of the pack openings, since the raw data here was collected from the original Twitch VOD, and there were a lot of segues in-between pack openings, so the creator of the YouTube video might not have caught them all.
  • Of the 896 packs, 6 were from the 3 promo quests.
