Description

15 Puzzle - Collect Numbers Row order, parity checks, brisk solves Overview: Sliding-number puzzler where you arrange tiles 115 by rows using a single blank space; efficiency comes from finishing rows cleanly and using parity logic so you never chase loops. How to Play As Expert (Mobile & Desktop): Goal: order tiles 1→15 with the blank bottom-right; challenge modes add move/time caps. Controls: tap/click tiles to slide into the blank • undo/reset • preview toggle • pinch zoom • Mobile: large tiles with haptics. Modes/Levels: 3×3, 4×4, move-capped runs, timed stars, daily scramble. Tips & Strategies: • Solve the top row (14) first, then lock it • Build the second row (58) using the right column as a buffer • For the final 2×3, route pairs (1314 and 910) before dropping 15 • Track parity: if two tiles need swapping, cycle around the buffer, don’t spin in place • Keep solved rows intact—work below them only • Turn off preview once you’ve framed the top row to train memory • Common mistake: dragging a tile across the board; instead, walk the blank to the tile. Game's Troubleshooting: • Slides not registering? Focus canvas/reset zoom to 100% • Board tiny? Enable Large UI • Choppy? Lower effects; cap 60 FPS • Progress missing?
