The classic block-placing game, turned upside down. Down in the deep sea the pieces do not fall. They drift upward like bubbles and settle against the ceiling, or against the blocks already floating there. Everything you know about stacking blocks still applies — it just runs the other way. HOW TO PLAY • The tray at the bottom holds three pieces. • Tap a piece to rotate it clockwise. • Drag a piece onto the board and let go: it drifts upward. • While you drag, a ghost outline shows exactly where the piece will come to rest. • Once all three pieces are used, the tray refills. THE CATCH • Fill a line completely and it clears — then the blocks beneath slide up to close the gap. • The red band along the bottom is the danger zone. Nothing can settle there. • The run ends when not one piece in your tray fits anywhere on the board. Every placement is a decision about the pieces you cannot see yet. SCORING AND LEVELS • 1, 2, 3 or 4 lines score 100, 300, 500 or 800 points, multiplied by your level. • Clear lines back to back and a combo bonus stacks on top. • Every 10 lines the level goes up: pieces drift faster and points multiply. • Each level-up also pushes a partly filled garbage line in from the ceiling, driving the stack down toward the danger zone. COMPETE WITH THE WORLD • A global leaderboard with two boards: the last 24 hours, and all time. • Pick a nickname, fly your country's flag, and see exactly where you stand worldwide — your true rank is shown even when you are nowhere near the top 200. • Share your rank with a tap. ALSO WORTH KNOWING • Plays offline. Only the leaderboard needs a connection. • Free, with occasional ads. No in-app purchases. • Available in English, Turkish and Spanish. The pieces are already rising. How long can you hold the line?
