game also periodically presents the player with "Challenge Hands", giving him or her a limited amount of time to create a specific hand. The challenges vary in difficulty and award increasing amounts of chips as the game progresses. Game modes Poker Smash provides four main modes of single-player play. In Action Mode, the card stack rises continuously and gradually speeds up over the course of the game, and the player keeps playing until the stack hits the top of the playfield. Timed Mode limits game time to three minutes, challenging the player to score as many points as possible in that time. In Puzzle Mode, the player must clear all of the pre-arranged cards from the screen. Cards do not rise in this mode, and the player has an infinite number of moves and infinite time to solve each puzzle. An additional Practice Mode is provided to allow players to learn how to play the game and practice chains – this mode does not save scores or upload statistics to the online leaderboards. Multiplayer In addition to the single-player modes, Poker Smash also provides a local split screen multiplayer mode and an Xbox Live "tournament" mode that supports up to five players simultaneously. In both modes, a limited number of chips is given to each player, and the objective is to win all of the chips from all the other players. As a player creates hands, the value of those hands is deducted evenly from the other players' chip stacks. If a player loses all of his or her chips, that player is eliminated from the game. Each player takes turns being the "dealer", and while a player is the dealer, he or she can drop "garbage blocks" on other players by forming odd-numbered chains (blocks are sent on the player's third, fifth and seventh chains, and so on). To clear a row of garbage, the player must form a legal hand that touches that row – this causes the garbage row to turn into new cards. The game supports both Ranked and Unranked online matches, with the Ranked mode utilizing the Microsoft TrueSkill ranking system. The game also supports online leaderboards, tracking players' best scores, longest chains and highest TrueSkill ranking, among other statistics.
