Drag the rock into another one with the same number and color. After similar rock combine, rock color and number will be increased. Merge them into a bigger number.
One button. Rising speed. No second chances. That is the arcade formula and it has not changed much in forty years because it does not need to. A session is a run of attempts where the first few are warm-ups and the later ones are tense. You stop noticing the music. You stop blinking. Then you clip an edge and it is over, and you tap Play again.
Nothing to learn, nothing to install, and a run of Stone Merge fits inside a single song. It is the kind of game that is good when you have five spare minutes and bad when you have five spare hours, because you will use all of them.
Suits anyone from about eight upward with decent reflexes. Adults looking for a palate cleanser between longer games, and phone users who want something to do with one thumb while standing up.
