Artificial intelligence
The AI uses only its hand, public cards, the allowed history, and the legal actions sent by the server.
Easy
Chooses only among legal actions, with some randomness and no deep lookahead.
Normal
Uses a stable heuristic strategy, taking into account the score, the turn, and the visible cards.
Hard
Evaluates multiple action sequences, remembers public information, and limits tactical mistakes.
- Hint AI prioritizes: turn over a hidden card, free a column for a King, build a foundation without blocking a run, then draw.
- The hard solver searches for multiple moves and avoids recycling loops.
