Pentago is a fast and fun strategy game that is both simple and sophisticated at the same time.The object of the game is to create a row of five marbles, in any direction. But the mind twisting part is that you will also twist one of four game blocks as part of your move. This causes the game board to constantly change, making for a perpetually challenging game experience, both for beginners and masters alike. Pentago was invented in Sweden late 2004 by Mindtwister AB and is now being introduced to the American markets. Contains small parts, not sutible for children under 3 years of age.
