The games are puzzle-based platform style affairs that require a little thought along with pixel-perfect leaps into the unknown. The most common puzzle requires players to smash up nearby objects to reveal pieces of Lego, which are then hastily assembled into some sort of device or vehicle to help solve the conundrum at hand.
Often the player will switch between control two characters to solve puzzles, using each character's skills and strengths to succeed. Bring an extra player into the mix and exciting co-op nonsense ensues. The whole lot is wrapped up in a healthy slice of good humour that gently lampoons the original source.
