Gem Match

Swipe a gem towards a neighbour, or tap two neighbours, to swap them · Keyboard: arrows to move, Enter to pick, Enter again on a neighbour to swap

Level: 1
Moves left: 25
Score: 0
Target: —

Every gem has its own shape as well as colour. A swap that makes no line slides back and doesn't use a move.

The prompt

Make a match-three game in one HTML file on an 8×8 canvas. Swap neighbouring gems by tap or swipe; clear runs of three or more; let gems fall and refill with cascades that raise a combo multiplier. Four in a line makes a striped gem that clears its row or column, five makes a star that clears a whole colour. Levels with a move limit and a target score, a hint after a pause, and an automatic reshuffle when no move is left.

Claude wrote this game from a short brief like this one. It was then played, tested on phones and tuned before it went up here.

How to play
