Unlock Block is a free puzzle game. This is the high-stakes world of sliding puzzles where players try their hand at unlocking a series of increasingly difficult block-based puzzles. Your mission, should you choose to accept it, is to slide the villainous pink blocks out of the way of your hero blue block. It sounds easy but it will require the ability to think ahead, think backward, think sideways, and finally think upside down. Sliding puzzles are an ancient form of entertainment and are important in understanding spatial awareness. None of the blocks are of the same size, but all of them are laid out in either horizontal rows or vertical columns. You will need to figure out what needs to be moved where and when if you wish to open up the entrance of the cell in this amazingly fun block puzzle style game. If you like sliding puzzles you will like this game. How fast can you make it to the forty-fifth level? You must play to find out for yourself.
On your desktop computer or a mobile device use your mouse or finger to select a block and slide it left, right, up, or down. You are trying to clear a path between your blue block and the cell door in order to escape.
