The idea

What is Sumfold?

Sumfold is a calm sliding-number puzzle in the style of 2048. Swipe to slide every tile on the board; when two tiles with the same number meet, they merge into one with double the value.

You choose your board size, from the classic 4×4 up to 8×8, and your goal: 512, 1024, 2048, 4096 or Endless. Every board size keeps its own game, so you can switch and pick up where you left off.

How to play

How a game of Sumfold flows

1

Choose a board and a goal:

Pick a board size and a target tile, or Endless. A short optional lesson shows how tiles merge the first time you play.
2

Swipe:

Every tile slides as far as it can in the direction you swipe.
3

Merge and grow:

Matching tiles join into one, and a new small tile appears after every move. Undo up to ten moves, or ask for a hint.
4

Reach your goal:

Celebrate, then keep going as far as you like. Your stats and personal best for that board size are updated.
