Unlock Me: Brain Puzzle

Slide the bars. Let them fall. Free the key.

Unlock Me is a sliding block puzzle with one big twist: gravity. Drag a bar sideways and everything that was resting on it drops. Get the red key block down into the lane with a clear path, and it shoots out through the lock.

One move can start a chain of falls, and a fall can't be taken back by sliding the bar home again. So look first, then move.

★ 300 PUZZLES, ALL SOLVABLE
Every level has been checked by a solver. Each one has a real solution and a par: the fewest moves that can do it. Match par for three stars.

★ 6 WORLDS, EACH WITH A NEW IDEA
• Bars and pillars: bars slide, tall pillars only fall
• Anchored: bolted ledges that never move
• Ice: bars that glide until something stops them
• Glass: breaks if it lands hard, or if something lands hard on it
• Balloons: float up and carry what sits on them
• Magnets: a pair that always slides together

The first levels of each world teach the new piece. After that it mixes with everything you already know.

★ NO RUSH
No timers. No lives. No energy bar. Take as long as you like on every level.

★ HELP WHEN YOU WANT IT
• Hint shows the next best move
• Undo takes a move back, and the first undo on every level is free
• Stuck for good? The game tells you when a level can no longer be won, so you never push blocks around a dead position
• Skip a level and come back to it later

★ THREE LOOKS
Warm Wood, glowing Neon and sweet Candy, each with its own board scenery. Turn on the Lively board and the scene moves: clouds drift, birds cross the sky, lights twinkle.

★ MADE TO FEEL GOOD
Blocks squash when they land and kick up dust. The key winds up before it runs for the lock. Sounds and gentle vibration follow every move, and both can be switched off.
