ReThink 4 is a puzzle game set in a peaceful futuristic setting, with many puzzles that use lasers, the behavior of light and its colors to create challenging challenges to solve. Use the newly added and already proven game mechanics to make your way through the beautiful game world, which is now filled with even more puzzles than in the previous games. ReThink 4 features over 60 puzzles that use both new and old features to keep the gears turning in your head. All the puzzles follow the same set of rules, but often have a twist that will make you think about your decision, and often rethink it. Unlike previous games, in ReThink 4 you can freely move around the area wherever you want and solve most of the puzzles in any order. Recycled cubes puzzle elements.
