Solve every board game one move at a time.

Tap a cell to set the position. A full minimax search returns the optimal move and proves whether the game is a win, loss, or draw.

Drop discs into the 7×6 grid. A negamax search on bitboards (after Pons) with center-first ordering, anticipated-loss pruning and a transposition table returns the best column and a per-column evaluation.

Enter your dice and scoresheet. A precomputed expectimax table returns the optimal keep/reroll and category choice.

Track suggestions and reveals live. A SAT solver narrows down possible envelopes; Monte-Carlo sampling gives per-card probabilities.

Mark your shots as miss, hit or sunk on a 10×10 board. The solver enumerates every legal placement of each remaining ship, builds a probability-density heatmap and suggests the next shot.

Race-and-block game on the 9×9 grid (à la Quoridor / barricade.gg). Place barricades to lengthen your opponent's route while keeping your own path open. Iterative-deepening negamax with the Glendenning shortest-path-difference heuristic suggests the best move.

The classic 24-character deduction game. The engine ranks every encoded question by worst-case eliminations (greedy half-split = proven optimum for binary questions) and you can also toggle characters manually for homemade clues the solver can't encode.

Set up any Minesweeper position on a grid of your choice. The helper enumerates every consistent mine assignment on the constraint frontier and reports per-cell mine probabilities — including which clicks are provably safe and which cells are provably mines.

Enter every player's dice count, your own hand and the current bid. The engine computes the exact binomial probability of every legal raise, plus Dudo and Calza, and recommends the action with the highest survival probability — the same expected-count rule that converged CFR policies for Dudo settle on.

Enter your guesses and the colours Wordle returned. A minimax partition solver (Selby 2022) finds the optimal next guess, guaranteeing a solve in at most 5 moves with an average of 3.4212 from the opener SALET.
