TrickTacToe is a card game where players try to play three X or O cards in a row (horizontally, vertically, or diagonally), taking the 3 cards as a trick and scoring the points on the cards. Cards are played by matching same colors to adjacent sides. Cards can also my played on top of existing cards, as long as they are still adjacent to a card in play AND the number on the new card is a lower value than the one it is covering.
