Merge Tiles: one-prompt sliding-tile puzzle game for Claude Code

Slide the tiles, match the numbers and watch them merge. Every move brings in a new tile, so the board fills up fast unless you plan ahead. Pick a quick 3 x 3, the classic 4 x 4 or a roomy 5 x 5, each with its own target tile and best score. Made a mistake? Undo your last move, even after Game Over. Reach the target to win, then keep going for a high score. Arrow keys on a computer, a swipe on your phone. Paste the prompt into Claude Code and it builds the whole game for you.
