Psychic Detectives

There are 3 decks of cards: means, motive, and opportunity. Each deck is made of pairs of cards. There are four pairs of means, five pairs of motives, and six pairs of opportunities. At the beginning of the game, each deck is shuffled, then one card is removed from each deck. After that, all three decks are shuffled together and dealt out into 7 piles. At all times, the players will know how many cards there are in each pile, and which deck those cards came from. On each player’s turn, they select a pile, look at all the cards in that pile, then choose one card in that pile to move to a different pile. After each player has had 15 turns, each player chooses one of those piles. The player who chose the pile that has the most cards that match the cards that were removed at the beginning of the game, wins.
