Only ThinkFun could transform the classic peg-solitaire jumping game, "The GreatThirteen," into such a rich, multi-level playing experience! With a lily-pad playing surface, 12 adorable Happy Hopper frogs, and 40 original puzzle challenges, Hoppers is entertaining for all ages. With the new, "red-hot" version comes a new twist--no matter how you get the other frogs off the board, the red frog has to be the last one standing. Ages 8 to Adult. Having fun is great way to learn with ThinkFun & Think Fun games. ThinkFun games engage kids and educate kids. They challenge players and nurture the thinking skills important to growth and development. Our games aren’t designed to simply occupy a child’s time.
