Play 24 Game online. Double digits 1-24. Includes all 10,094 solvable cards (the official double digits 24® Game deck by Suntex only contains 192 cards). There are 10,212 total possible solvable cards but 118 were removed because these require using non-integer numbers (i.e., fractions, decimals) to get a solution. For example the set [2,4,10,10]. 9s are underlined with red to distinguish them from 6s.

Difficulty ratings were automatically assigned by number of distinct solutions. The more solutions, the less difficult. The less solutions, the more difficult. There are 2,370 easy, 4,321 medium, and 3,403 hard cards.

If practicing for a tournament that has double digits, it's probably better to practice with the actual official double digits deck because the online version I created has so many more cards that will never show up in the tournament. But if you're like me and just want to play for a fun challenge, then this will provide a much vaster pool of them.
