In New game (+), each player can be a human or a bot: random, greedy (best move right now) or Monte Carlo (tries the moves in many random games: set how many; 500 take about a third of a second, more play stronger and slower). Bots play by themselves; each player's last tile glows in their colour, the latest move's stronger. Z takes back moves to your last turn.
Hover a meeple, a ring or a feature in the list to see what it is and what it is worth. The next tile is drawn only when a turn ends. 7 meeples each; one comes back when its feature is completed and scored.
The most meeples on a feature score it; a tie scores for all tied.
