How to play Chain Reaction

Chain Reaction is a one-tap puzzle of timing and placement, in the style of Boomshine. Orbs drift across the screen; you get a single tap that creates one blast, and every orb caught in a blast erupts into its own, chaining outward.

Controls

Tap or click once per level — that's your only move. The blast appears where you tap, lingers briefly, then fades.

How levels work

Each level asks you to catch a minimum number of orbs in the chain. Set off your blast where orbs are converging, not where they currently are: the first explosion needs to catch two or three orbs almost immediately so the chain can feed itself before blasts start fading.

Tips

Patience is the real skill. Watch the drift for a few seconds and wait for a cluster to form — the difference between tapping into empty space and tapping into a converging knot of orbs is the difference between a fizzle and a full-screen cascade. Density beats position: a tight cluster near a corner beats scattered orbs in the middle. Later levels add more orbs but demand a higher percentage, so the waiting game matters more, not less.
