🪙 Coin Stack

Coin Stack is a casual mini-game of timing and focus. A coin swings left and right at the top of the screen, and your goal is to drop it right onto the center of the growing tower below. The rule is simple, but as the tower rises the coin moves faster and the tension builds. It runs instantly in your browser with no install, and your best score is saved so you can compete against yourself.

Controls are dead simple: tap the screen or press the space bar to drop the moving coin. The smaller the offset from the coin below, the more stable the stack — and an almost-perfect drop triggers a "Perfect," snapping the coin to center. Chain Perfects to build a combo. Miss by too much, though, and the coin slides off, ending the run.

Tips for a high score: aim for the moment the coin overlaps the one below, not just when it crosses the middle of the screen. A dashed blue guide marks the center of the top coin — use it as your reference. As the speed climbs, tapping a split-second early becomes key. Rather than mashing frantically, focus on placing each layer precisely; that patience stacks higher in the end.

Coin Stack is perfect for a quick break or while waiting. Take turns with a friend to see who stacks higher, or keep coming back to beat your daily best. On mobile you can play with a single thumb tap, making it easy to enjoy on the train or on the go.
