From RoughEdge Software:
KuBus is not your typical match-3 game or logic puzzle. It combines both by using a match-3 mechanic to clear and solve the logic puzzle. The full version includes 99,999 unique puzzles, each with at least one solution. Full version also includes the ability to save and load your puzzles as well as being able to jump to any puzzle. Use special blocks in the full version to unlock some fun and exciting game play. Each puzzle is numbered, so challenging your friends to beat your score is easy and fun. If you really want a challenge try the stacking or continuous mode. Stacking mode forces blocks from the bottom of the play screen to the top, with ever increasing speed. Once at the top, game over. Continuous mode refills the blocks removed until the block counter reaches zero while barricade blocks try to throw you off. Add a timer or change to sequence mechanic to take the challenge to a whole new level. Running up your score, getting a perfect clear or just having the satisfaction of beating your friends, KuBus provides hundreds of hours game play.
