This is a variation of the popular "Match and Eliminate" game(other names: Kyodai,"Match It"), by changing rectangle to hexagon.
Touch to select objects. If you select one object are "same" and "can be linked" with the last one, they will be eliminated. "Can link" means can be linked by one or two straight line. If you eliminate all objects in limited time, you win. You need sharped eyes and fast fingers :)
Up to 4 themes are supported: "Color blocks", "Flags", "Fruits and Vegetables", "Flowers"
