Merge the blocks, level up, but beware of the red blocks in this puzzle game for you! How to play? When you swipe the screen, all the blocks move together in that direction. Try to push blocks with the same number together to level up. But beware of the blocking red blocks! Try to get three or more of them next to each other, to remove them. '25' is the perfect marriage between a sliding block puzzle game and a match-3 game. So tell me, what is your highest score? @BartBonte
