Spark chain

Chase the fire. Chain the combo. Don't let it die out.

Spark Chain is a fast, one-tap arcade game built for quick bursts of chaos. Tap any tile to ignite it — same-colored tiles catch fire and spread in a real-time chain reaction. The twist: while the fire is still spreading, tap somewhere else fast enough and you feed the combo, pushing your multiplier higher and higher.

How to play

- Tap any tile to set it ablaze.

- Connected tiles of the same color catch fire and burn in sequence.

- Tap again before the flame dies down to keep the combo alive — the faster you chain taps, the bigger your multiplier (up to x5).

- Hunt for ⚡ Wild tiles — igniting one blasts every tile nearby, regardless of color.

- Keep clearing to fill the Heat gauge. Once it's full, INFERNO mode kicks in: 4 seconds of double score and a longer combo window.

- Score as high as you can before the 90-second timer runs out.
