*** Featured as "App of the Day" on the App Store! *** Thinkrolls Space is a child-friendly puzzle game that’s out of this world. Colorful heroes boldly roll where no Thinkroll has rolled before, in over 200 mazes set across seven unique planets. A cast of oddball aliens will make you grin from ear to ear. But you’ll need brains and nimble fingers to reach your goal—and catch the waiting UFO that will beam your Thinkroll to the next fun-filled planet. CLOSE ENCOUNTERS Thinkrolls and Thinkrolls 2 introduced our revolving heroes. Thinkrolls: Kings & Queens added exciting new concepts—and dragons. Now Thinkrolls Space blasts the award-winning series into outer space. You’ll meet goo monsters, bleeping robots, spring-like soprano aliens, and cheese monsters who love munching moon cheese. You’ll face vanishing rainbow bridges, plasma fields, teleporters—and more. Each of these can help or hinder. You must figure out which—and how to move and match objects to clear a path, get the key, and open a gate to the next level. REACH FOR THE STARS Two difficulty modes and unlimited penalty-free retries ensure the 200+ level journey is stress-free for children and adults alike. Along the way, stars and hearts can be collected, and later used to unlock 24 unique alien Thinkrolls. Throughout, players are encouraged to experiment.
