Card matching with eight emoji themes, four difficulty sizes and four modes. The deal is a real Fisher and Yates shuffle, measured uniform over 60,000 boards, and a turn is a state machine so two fast clicks cannot strand a card face up.
Slide tiles to combine them and reach 2048. Each tile merges at most once per move, checked exhaustively against the rule, and the board total printed under the grid always equals everything ever spawned. Undo, touch controls and score tracking.
Tic-tac-toe against a minimax opponent, or a friend on the same device. Four difficulty levels, each a stated rate of playing a move that is not the best; on Impossible it cannot be beaten, proved by walking all 16,752 games.
You hold 16 and the dealer’s up-card is a 7.

Basic-strategy result
Hit (not stand), the mathematically correct play
Basic strategy is the published decision table: with a 7 up the dealer will most often make 17 or better, so standing on 16 loses more often than the bust risk of hitting. The table applies exactly because the rules it assumes are settings you can see: a six deck shoe, the natural paying 3:2 or 6:5, and the dealer standing on all 17s or hitting a soft one. The sentence at the top of the table is built from those settings, so it cannot say one thing while the table does another.
Try to beat the dealer by getting as close to 21 as possible without going over. Hit, stand, double down, or split, every hand is a new decision. Blackjack balances luck and strategy in a way few card games can match.

Each card has a point value: number cards are face value, face cards are 10, and an ace is 11 unless that would bust the hand, in which case it is 1, so two aces are 12 and never 22. A hand is SOFT while an ace in it is still worth 11, which is what makes soft 17 a different hand from hard 17: it cannot bust on one card.
Blackjack has more variations than any other game here, and the ones that change the odds are settings rather than assumptions. A natural pays 3:2 or 6:5, and they are different games: on a 100 stake that is 150 in winnings against 120, worth about 1.4 percentage points to the house, which is more than the whole edge of a good 3:2 game. The dealer stands on all 17s or hits soft 17, which is the single biggest rule variation in blackjack. Both are toggles here and the sentence at the top of the table is built from whatever they are set to, so the page cannot say 3:2 while the table pays 6:5. Splitting two ten-VALUED cards, doubling after a split, how many times a hand may be split, and one card to split aces are all named too.
The shoe is six decks, checked to be exactly six of every rank in every suit, and it is cut at 78 cards remaining and reshuffled BETWEEN hands rather than part way through one, so a card already on the table can never come out again. Money is counted in whole chips, which means a 3:2 payout on an odd stake is not representable: a 5 stake is paid 7 rather than 7.5, the page rounds down the way a table does when it cannot make change, and it says what odds that really was.
The hint, when you turn it on, is the published multi-deck basic-strategy table rather than an approximation of it: it splits a pair of nines against everything but 7, 10 and an ace, hits soft 18 against 9 and up, doubles soft 17 against 3 through 6, and surrenders hard 16 against 9 and up.
No. This is purely for entertainment and practice, no real money is involved.
A set of optimal decisions for every combination of your hand and the dealer's up card, based on probability.
Yes, and by default any two ten-valued cards as well, so a king and a queen can be split. That is a real variation rather than a detail: the other convention requires the same rank. Split hands can be split again up to four hands, and split aces take one card each.
On a 100 stake a natural pays 150 at 3:2 and 120 at 6:5. It is worth about 1.4 percentage points to the house, which is larger than the entire edge of a well-played 3:2 game. Both are here so you can see the difference, and the table always says which it is paying.
That is a setting. It is the biggest single rule variation in blackjack and is worth about 0.2 percent to the house when the dealer hits. The sentence at the top of the table says which rule is in force.
Because chips are whole numbers and 3:2 on 5 is 7.5. The table rounds the winnings down, which is what a real table does when it cannot make change, and the game records that the odds paid were 1.4 to 1 rather than 1.5.
