Getting started
Sokoban-Lettres controls
Sokoban-Lettres is played with the keyboard on a computer and by swiping on a phone. Every command produces exactly one step: no automatic movement, no shortcut that plays for you. Here is everything you can do, and what each action costs.
On the keyboard
Sokko moves with the four arrow keys. The W, A, S and D keys work too. The game recognises them by their physical position on the keyboard rather than by the printed letter, so on a French AZERTY keyboard the keys Z, Q, S and D move Sokko up, left, down and right.
Holding a key down does not make Sokko walk continuously: each press counts for a single step. This avoids accidental pushes, which are the leading cause of deadlocks. Movement keys are ignored while you are typing in a text field.
The Escape key closes secondary windows: the confirmation before going home, the share sheet and a level’s leaderboard.
On a touch screen
On a phone or tablet, swipe in the direction you want, anywhere on the grid. The gesture must travel at least 20 pixels to count, so a simple touch never triggers a step. The direction taken is the axis closest to your gesture.
Each swipe is one step. Tapping a square to send Sokko there is not supported: the game prefers each move to be a deliberate choice, since every one of them counts in the score.
The action buttons
Below the grid, a bar holds the actions that are not moves. They deliberately have no keyboard shortcut, so they can never be triggered by mistake.
What each action costs
- Undo takes back the last move. The game remembers up to 200. An undo costs one life.
- Reset puts the grid back to its starting state. It is free, and the move counter, the hints on screen and the timer all start again from zero.
- The three hints — Crate, Target and Path — cost one life each.
- Changing difficulty during a game restarts the level in the new mode.
Once the level is won, undo and hints are switched off: the solution is recorded as played.
When a position is blocked
If a box ends up in a position from which it can no longer reach its target, the game pauses movement and opens a window offering to undo, reset or go home. The positions it detects are explained in spotting and avoiding deadlocks.
