Block Escape: Color Slide

Block Escape is a sliding block puzzle with one rule: get every block out. Drag a block and it slides until something stops it -- a wall, a fixed steel block, or another piece. Reach a door of its own color and it leaves the board. A door of any other color is just wall. Clear the board to win. That is the whole game. What makes it hard is that the piece you need to move is almost always behind the piece you do not. NO TIMER, NO LIVES, NO FAILING Most puzzle games of this kind put a clock on you. This one does not. There is no timer, no move limit, no lives to run out and no way to lose. Starting over is always free and one tap away, and the puzzle waits exactly as long as you do. Play a level in twenty seconds or come back to it tomorrow. EVERY LEVEL IS SOLVABLE -- GUARANTEED Levels are not scattered and hoped for. Each one is built backwards from a solved board, so a solution provably exists, and every single level is then checked by an exhaustive search before it ships. The app knows the shortest possible solution to every puzzle, and shows it to you as a target. 300 LEVELS, AND A CURVE THAT IS MEASURED The difficulty curve is measured, not guessed. Boards grow, colors multiply, fixed obstacles appear, and long bars and L-shapes arrive to create the real jams. Early levels teach; later ones take fifteen moves and some staring. BUILT TO BE READABLE Every color also carries its own shape -- a dot, a triangle, a square, a diamond, a cross, a bar -- and each door carries the matching one. If you are color blind, this game is still completely playable. That is not an accessibility setting to switch on; it is just how it is drawn. ALSO • Every puzzle is built into the app, so the game itself needs no connection. Only the adverts do. • Your puzzle saves itself, mid-move. Close the app and pick up exactly where you were. • Gentle sound and a quiet music bed, or turn both off with one tap. • One-handed portrait play, made for a commute or a queue. • No account, no sign-up, no email. NO NONSENSE • Ads keep it free. A short advert may play when you leave a finished level, never in the middle of one and never in your first few. On screens with the room for it a small strip sits below the buttons at the foot of the puzzle screen, in its own space, never over the board. Beyond those two, every advert is one you choose to watch, to reveal a move, take a move back, or skip a level you have been stuck on. Starting a level over is always free. • In-app purchases are optional and small. Keys buy the three boosters -- show the next move, take moves back, skip a level -- and a single one-off purchase removes both of the adverts you did not choose. Nothing is locked and no level is for sale: all 300 stay free, sparks are earned only by playing and buy color finishes and nothing else, keys also arrive with the daily gift and every rank, and every advert you choose to watch still works exactly as it did for anyone who would rather not pay. • No tracking by us. Your progress is saved on your phone, and backed up to Play Games if you are signed in. Whether you call it a block escape puzzle, a color block game, a sliding block puzzle or an unblock game, Block Escape is the calm, unhurried version of it. Free to play. Get every block out.
