Hot Jewels

Cut gems glitter under lamplight inside a square grid. Trade positions until three stones of one colour sit together and they shatter into sparks. This is the pattern the genre has used for so long that it barely needs describing.

The appeal of a plain version is that nothing has been bolted on top. No character speaks to you, no map of stages to walk through, just the grid and the stones. Anyone who played something similar a decade or more ago will be up to speed inside ten seconds with nothing to relearn.

With no distractions layered over it, the only thing left to measure is how quickly your eye finds a pair. Strong players are not thinking more deeply than anyone else; they are simply seeing faster, and seeing faster is a skill that repetition builds rather than a talent you either have or lack.
