Jump start your neurons by playing one of several brain challenging games using the fun and innovative playing board of GoBong! Play against an opponent or use one of the solitaire game rules to challenge yourself. Like its predecessor Last Mouse Lost, the playing area of Go Bong! consists of a rubber grid with raised 'bumps' that can be pushed down with your fingers. Once all of the bumps have been pressed, you can flip the board over and play again on the other side. To play, two players alternate turns pressing down one or more bumps in the grid, with these bumps needing to be in the same horizontal, vertical or diagonal row. Whoever pushes down the final bump loses. Go Bong! includes solitaire challenges.
