Plan your way through a quiet puzzle of rooms, edges, and unexpected connections.

Each level gives you a compact map of open rooms and closed spaces. Read the visible connections, choose a fold line, and create a bridge between distant rooms. Then move your marker one careful step at a time until it reaches the target.

Every decision has a cost:
• Vertical movement uses two steps.
• Folding uses one of your limited fold actions.
• Two undo actions help you test a plan without removing the need to think ahead.

The first 36 levels gradually introduce new spatial relationships. Early boards teach the basics of connected rooms and paper bridges. Later boards ask you to manage blocked spaces, fold order, and movement economy. Three consecutive valid moves reveal a small next-step preview without giving away the full route.

Finish a level to earn up to three stars based on your remaining moves and folds. Improve your best plan, revisit completed levels, and continue through six chapters at your own pace. A fixed daily shape offers another compact board to study and solve.
