Weak machines still run smooth: why match-three is the right pick
If the first piece snaps instantly, the whole round runs smooth.
A match-three round needs fewer resources than any other browser genre: the board is a static grid, effects explode locally, and a server knows nothing mid-round. On a five-year-old office laptop with ten tabs open, the difference between an optimised game and a careless one is twenty seconds of waiting and a loud fan.
A quick pre-game test: open the game, sit still for ten seconds, then watch the fan and the smoothness of the first drag. If the first piece snaps instantly, the round will run smooth throughout. If it lags, try the effects switch in settings — most decent games ship one, and turning effects off rarely changes the rules.
This site arranges match-three by the weak-machine standard: small page weight, no autoplaying video, no 3D background effects. A match-three that needs a GPU to explain its rules has misread its player — someone who wants a light round between meetings, not a demonstration.
