The blocks you cleared come falling back. This is a falling-block puzzle where your toughest opponent is yourself. Every piece you place is recorded — and each time the clock loops around, it returns to the board in the same column, the same shape. Clearing lines alone won't save you: your own history piles up until it swallows the board. Clear lines through the returning shadows to erase their records for good and grow your score multiplier. How long can you hold back the tide of your own moves? Features - A run takes just a few minutes — perfect for short breaks - Easy controls: slide to move, tap to rotate, flick down to drop - No in-app purchases. Ads appear only occasionally on retry — never during play - A rule you won't find anywhere else: your moves become your enemies - Clear through the shadows to build your score multiplier - Works offline. Beat your best, then take on the world leaderboard
