The 3 in a Row game is played by forming three discs of your colour in a row in this classic game for two. Game play assists with social interaction skills development and concentration through play. The panel is made from solid commercial grade HDPE material 19mm thick and is especially used in an outdoor environment. Mounting holes must be drilled on installation which allows you to place the sensory panel onto timber upright posts or mount onto an existing play structure or wall. Panel size: 73.5cm x 73.5cm x 19mm.
