5555xLane

Study the board, clear the blocked lane and guide each target piece through the exit. Work through 80 hand-seeded sliding-block layouts across Foundations, Advanced and Sequential Exit chapters. Each board has a reference move count, a clear miniature preview and a saved personal record. Slide horizontal and vertical pieces only along their own direction. Move one cell or several in a single drag, undo and redo at any time, restart a layout or pause and return later. Reachable spaces are highlighted for a selected piece, and two-stage hints explain the blocking chain before offering one suggested move. The final chapter introduces two targets that must leave in sequence. Completion summaries compare your moves with the board reference, count undos and let you retry, continue or review a sample route. Adjust drag sensitivity, tactile and sound cues, board motion, direction markers and visual themes. Progress, preferences and records stay on your device, and the puzzles are available offline.
