Phase 10 is a card game that combines elements of strategy and luck. Players aim to complete ten specific phases, which consist of sets or runs of cards. Each player takes turns drawing and discarding cards to achieve the current phase while trying to block opponents from completing theirs. The game is played with a special deck of cards numbered 1 to 12 in four colors, along with wild cards. Players score points based on the cards left in their hands when someone completes a phase. The first player to complete all ten phases wins the game.
