Tixel is a two-player abstract game designed by Martijn Althuizen that's a follow-up to Tix, by the same designer. The name comes from the playing pieces, which are basically pixels (squares) with a curved indentation on one of their edges.
The aim of the game is to be the last player able to make a legal move. Chaining moves is invaluable as this temporarily unlocks three additional move types. If a tixel that is moved becomes inactive at its end position — i.e., it's sacrificed — a player can take an extra move if he so chooses; aside from placing or moving a tixel, he can now remove a tixel from the board, activate an inactive tixel, or pivot an active tixel to reorient its hollow side.
board (pad), 20 special pieces in 2 colours (10 each), carrying case. The pieces are made of 8mm thick laser-cut acrylic (black and ice).
An expansion for Tixel which consists of 4 extra pieces for each player is also available (see image below). Expansion pieces are different from regular pieces in that they are completely square-shaped instead of being hollow on one side. For each expansion piece used, remove one tixel piece from the game. The expansion pieces can be used to handicap a stronger player. With two expansion sets, the original Tix game can also be played on the Tixel board. The price for the expansion is 10 Eur.
