Arcade games, while exciting for a while, can get a little old if played too much. Not so with this set from K'NEX. Follow the instructions in the enclosed book to build arcade games out of the baseboard and abundant parts. Then, when you're ready for a new challenge, reconfigure the board to create an entirely new game. The instructions are helpful in getting started but we had the most fun creating our own quirky versions, as the kit alternated between being an arcade game and a construction set. Games can be set up for one or two players. --John Moe
