Reinforcement Learning Applied to a Game of Deceit

Skull is a simple game of deception played by 3-6 players. Each player receives four tiles. Three of these tiles depict flowers, with the fourth depicting a skull. At the beginning of a round, all players simultaneously choose one of their tiles and places it face-down on the table. Then play proceeds clockwise, with each player taking one of two actions: Add or Bet. If a player chooses Add, they place another tile face-down on top of their stack. If they Bet, they choose a number and from then onward, each player has a choice of two actions: Raise or Pass. If a player Raises, their bet (higher than the previous bet) replaces the previous bet. If a player Passes, they are out of the round. Once all players but one have Passed, the player who made the last bet must turn over a number of tiles equal to their bet, starting with their own stack. If they turn over only flowers, they win 1 point. If they turn over a skull, they permanently lose one of their four discs (losing all four means that a player has lost the game). The first player to win 2 points wins the game. 2 Motivation
