In a Grove is a bluffing and deduction game where the player who makes too many false accusations loses the game.
The game is played in rounds. Each round, each player receives one of eight silhouettes (numbered 2-8 with one empty), while three silhouettes are placed as suspects in the center of the table and the last silhouette is designated as the victim. You must determine which suspect is the guilty one, either to accuse him or to lure other players into accusing someone who is innocent!
All players secretly look at their silhouettes, then pass them to the right and look at the new silhouette they received. The first player of the round secretly looks at two of the three suspects and, if desired, exchanges the victim for one of these suspects. This player then places a colored accusation marker under one of the suspects. The next player looks at the two suspects not marked with an accusation marker, then places their own colored accusation marker, covering any markers already under that suspect. This continues until all four players have placed an accusation marker, with each player not allowed to look at the suspect just accused.
The round ends and players reveal the suspects. Who is to blame? The suspect with the highest number - unless the #5 is among the suspects, in which case the suspect with the lowest number is guilty. (The suspect without a number is always innocent.) Anyone who accused the correct suspect gets their charge marker back. Any misplaced markers are turned over with the colored side down and given to the player holding the top marker of the pile.
At the end of a turn, if a player has eight or more markers - or has no markers - the game ends and that player loses.
