For up to four players. This is an easily learned game even for my 7 year old. Our entire family could join in including teens. This game provides hours of fun, making you think and strategize without having to invest hours in a long game. The games are just long enough. I would recommend this game for 1st and 2nd grades as well for learning patterns and strategy. It is a great way for them to develop critical thinking. I highly recommend this game as well as others we have purchased from Mindware.
