Twoward: Tandem Merge

StackForge Studios

In-app purchases

About this game

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

Also included free: the 60-level Chain Ladder, Daily Chain and unlimited 5×5 chain play. Optional Pro adds the 6×6 chain board, premium chain tile themes, longer run history and Daily history sync for signed-in players. Tandem and Ladder progress remain local.

No forced ads, lives, energy timers or paid retries. A one-time purchase unlocks Twoward Pro. StackForge Play Pass provides Pro access across participating StackForge games.
