| Gallery Solitaire
The game starts by dealing 32 cards from the stock to the
foundation (3 rows) and to the tableau (bottom row). Building
rule: by suit, up in sequence (rank difference: 3; top
row: 2-5-8-J, middle row: 3-6-9-Q, bottom row:
4-7-10-K).
Detailed Rules
- New: Start
a new game
- Undo: Undo
one or more moves
- CAP: Level
of computer aided playing (0: no help), e.g. movable cards
are indicated by a green bar.
- # of tries: NNN:
At the end the program tries the same starting situation
NNN times with a non-strategy (start it with Do!).
At the end of the game you can
- let Gallery play many games with a simple "do-all-one-can"
strategy and compare your score with this evaluation. This
non-strategy consists of doing all legal moves in random
order. Because of the great amount of unpredictable situations
even a good player looses games (about 20%).
- start a new game.

Hidden features
Entering a number of trials in the format NNN.ppp performs NNN
trials with an alpha value of 0.ppp, e.g. 1000.98. The meaning of
alpha: if you do all possible moves in every situation you
can't achieve all possible results. In real situations it's sometimes
better not to do all possible moves. This parameter tries to simulate
such a behaviour. Experiment with 0 < alpha < 1!
Keys: "z": undo a move; "f": finish a game
automatically with the simple strategy.
