Twoward: Tandem Merge

Build two targets from one finite board. Tap a number, then an equal neighbor to merge into that cell. Reach the exact targets at A and B. No gravity. No random refill. Each merge changes the route ahead.

Tandem has 120 fixed, verified-solvable puzzles, with free undo and hints, and your progress saved on your device. Boards grow from 4×4 through 5×5 to 6×6 at your own pace.

Free: the first 16 Tandem puzzles plus one more each day, the ranked Daily Chain, and unlimited 5×5 Chain Merge. Twoward Pro opens all 120 Tandem puzzles at once, the 60-level Ladder, the 6×6 Chain board, extra tile themes, a weekly Streak Saver, longer run history and Daily history sync for signed-in players. Tandem and Ladder progress stay on your device.

No ads, lives, energy timers or paid retries. Unlock Twoward Pro once, or choose StackForge Play Pass (monthly or annual) — Pro in every StackForge game plus One Good Thing.
