About Twofold
Twofold is a sliding number puzzle on a 4×4 board. Every slide moves all the tiles at once, and two equal numbers that bump into each other fuse into their double. A new tile appears after every move, so the board slowly fills — plan your merges to reach 2048 and beyond.
How to play
- Swipe or press an arrow key — every tile slides as far as it can.
- Two tiles with the same number merge into one with double the value.
- Each merge adds the new tile's value to your score.
- A 2 or 4 appears after every move.
- The game ends when no slide can change the board.
Objective
Merge tiles into ever-bigger numbers before the board locks up.
Tips & strategy
- Pick a corner and keep your biggest tile there.
- Avoid swiping away from your corner unless you have to.
- Build a descending chain along one edge so merges cascade.
