About SokoSave Mobile
Sokoban is a popular logic puzzle game devised in 1980 by Hiroyuki Imabayashi and first published in 1982 by Thinking Rabbit. Sokoban is the Japanese word for warehouse keeper. In a game of Sokoban, you are a warehouse keeper responsible for pushing a collection of boxes to designated areas within a warehouse.
SokoSave Mobile is a version of Sokoban for Windows Mobile. It features crisp, simple graphics, intuitive game controls, and computer-assisted movement which makes game play fluid and enjoyable. SokoSave Mobile was written by Eric Sunshine <email@example.com>.

The rules of Sokoban are very simple, however, Sokoban puzzles can be quite challenging. To play, use the pusher to to push boxes across the floor into designated goal areas.
Boxes can only be pushed; they can not be pulled. Only a single box can be pushed at a time. Boxes can not move through walls. The puzzle is solved when all boxes have been pushed onto goals.
Tap on a pusher or box to select it, and then tap on the desired destination. If the destination can be reached (see rules), the pusher or box will move there automatically by the shortest path.
If you select the wrong piece, tap again to remove the selection, or tap a different piece.
The game also can be played via the up, down, left, and right buttons on the directional keypad when the move or cursor navigation mode is active.
If you make a mistake during game play, the playback history allows you to undo (take back) one or more moves. If you undo too many moves, you can redo one or more. Use the Playback Panel to manipulate the playback history.
- Undo All
- Undo all moves, returning the puzzle to its starting position.
- Undo a group of moves and pushes related to a single box.
- Undo Step
- Undo a single move.
- Redo Step
- Redo a single move.
- Redo a group of moves and pushes related to a single box.
- Redo All
- Redo all moves.
- Drag the trackbar knob to any position within the playback history.
- Replay, in slow motion, all moves from the puzzle's starting position. This is useful for reviewing the moves you made to arrive at a solution. If you do not want to watch all moves, tap on the puzzle to stop replay.
The playback history also can be manipulated via the playback navigation mode and from the Game menu.
As a convenience, the arrow keys on the directional keypad perform different functions depending upon the current navigation mode. The center action key on the keypad cycles through the navigation modes.
- Left and right arrows, respectively, move to the previous and next unsolved puzzle within a collection. Down and up move to the previous and next puzzle whether solved or not.
- Left and right arrows manipulate the playback history by performing undo and redo. Down and up perform single-step undo and redo.
- Arrow keys move the selected pusher or box one step in the indicated direction.
- A cross-hair cursor is displayed which can be moved with the arrow keys. The cursor acts as a stylus for non-touch-screen devices. The cursor is green at locations where it is legal to tap with the stylus, and red at illegal locations. To tap at the cursor's location, press the center action button when either green or red. The cursor becomes gray after a short amount of inactivity. When gray, the action key reverts to its normal behavior of cycling through navigation modes.
As a puzzle-solving aid, portions of the puzzle board can be highlighted to indicate reachable locations. Highlighting is shown when a pusher or box is selected, and hidden when no piece is selected. Highlighting can be configured via Menu > Options... > Highlight.
Several highlighting modes are available.
- Box Moves
- When a box is selected, locations to which the box can be pushed are highlighted.
- Movable Boxes
- When a pusher is selected, boxes which can be pushed are highlighted.
- Pusher Moves
- When a pusher is selected, locations to which the pusher can move are highlighted.
Several different scores are computed for each game.
- Moves (M)
- Number of pusher moves.
- Pushes (P)
- Number of box pushes.
- Pusher Lines (L)
- Number of straight lines during moving sequences.
- Box Lines (R)
- Number of straight lines during pushing sequences.
- Transitions (T)
- Number of transitions from moving to pushing.
- Box Focus (B)
- Number of times focus changes from one box to another.
- Pusher Focus (F)
- Number of times focus changes from one pusher to another. (Applies only to multiban puzzles, a variation with multiple pushers.)
