Drag one step. 1 and 2 make 3, then double it. Free undos every board.
Trio Ladder Drag and the whole board nudges one square — not all the way. Nothing merges until you let go, so you can see how it lands and pull back if you do not like it. A 1 and a 2 make a 3, and from there equal tiles double: 6, 12, 24, 48. Survive as long as you can, and a wrong move is rarely final — you can undo. WHAT YOU GET - Classic mode - Goal mode - Endless play — keep going until the board jams, and chase your best score - Nothing merges until you release, so you can preview a move and cancel it - Tiles move one square per drag, so where you place them matters - 1 + 2 = 3, then 3 + 3 = 6, 6 + 6 = 12 — a ladder, not just doubling - Free undos on every board — 3 to 6, more on hard - Start with a 384 booster placed on the side you actually build on - 1,000 goal puzzles with a fixed deck — the same board plays the same way - Works offline, no account needed NOTHING IS FINAL A board can jam, but a wrong swipe rarely ends the run — every board starts with free undos (3 on easy, 6 on hard), and an ad buys three more. Free to play with ads. No purchases required.
