19 games · a new board in each every day · no signup
Nineteen games from the card table and the game board, one new deal or position apiece every day. The nine card and tile games give everybody the same deal, which is what makes a leaderboard possible in games that are usually about luck. The ten endgames each start from a position where a single move keeps the result, and the position is played out against an engine that defends as well as it can.
The card games take the luck out by fixing the deal. Taire and Cell are solitaires with a proven minimum line. Mahj is mahjong solitaire on all 144 tiles. Pairs is Concentration with a real deck. Hands scores every row and column of a five by five grid as a poker hand, Hold values every video poker hold exactly, Shoe deals ten hands of blackjack off one fixed shoe, Crib values every cribbage throw, and Finesse is a double dummy bridge problem with all four hands face up.
The endgames are not checked against a key. Find the one move that keeps the result and the engine takes the other side, so you keep finding the right move until the game is over. Mate, Defend, Swindle and Queen are chess. Yose is Go, Turn is Othello, Check is checkers, Four is Connect Four, Gift is Quarto and Chain is dots and boxes. Those ten boards rank solvers by how many attempts the solve took, and a replay counts.
Taire or Cell if you like a solitaire with an answer. Hands or Hold if you know poker hands. Four if you want the shortest endgame, and Mate if you have done chess tactics before. Finesse and Yose are the deepest and worth a slow first sitting.
| Monday to Saturday | Tighter deals and longer forcing lines as the week goes on. |

| Sunday Edition | The biggest deal of the week in each card game, and the longest lines in the endgames: Defend holds for four moves, Queen wins in twelve and Yose moves to the full 9x9 board. |
Yes. One deal or position a day per game, so the board compares play and not luck.
The rules of each are stated on its page and enforced by the game. What they test is reading a deal or a position a few moves deep.
All nineteen, every day, no account required.
