Blox comes with a 4x4 wooden board and 16 tiles (8 yellow and 8 orange) marked with a line on the back side. In the basic game the players remove a tile from the edge of the board and then re-insert it on the board from another edge sliding the tiles in between horizontally or vertically. The objective of the game is to connect all 8 tiles of their color together. The game comes with 3 different variants increasing in difficulty: the players must not only connect their 8 tiles together but the lines on their tiles must also connect!
