This nifty little travel-size game offers brain-stretching varitation on the children's classic tic tac toe game. Not only does the player need to get 4 markers in a row instead of just three; he is also playing on two different boards at the same time. This is a very fun, very addictive game that will really help your child flex those mental muscles. It is the sort of game that is easy to learn but hard to master, which makes it great for players of different ages or ablilities. The pieces are magnetic, making this a wonderful game to play in the car or while waiting practically anywhere. The Herd Your Horses version features the same beautiful artwork as the Herd Your Horses board game.
