B-Cubed can lead to hours of playing. The levels get harder as a player goes through a game, and some of the levels are very difficult to solve. A player slides a cube using the keyboard's arrows with the goal being to pass over every single square on the board until reaching the final square. It may sound easy to do, but it becomes progressively more challenging. B-Cubed is one of many thinking games, puzzles and mazes at Coolmath-. Another game on the site teaches angles by having the player try to shoot a moving target.
