How do you play Spark Grid?

Press Ignite, then tap exactly one open cell to launch a wave. The wave cascades on its own through the grid, and you win the board by lighting every Goal cell while also covering at least the target number of cells shown above.

What's distinctive about Spark Grid?

You make a single decision — the ignition point — and then watch the whole chain reaction unfold through blockers, delays, and amplifiers. The skill is predicting the automatic cascade rather than tapping cell by cell.

How does a run end and how is score counted?

Each cleared board adds points based on the round, goals hit, and how far you exceed the coverage target, then advances you to a harder round. One cascade that misses a goal or falls short of the target ends the run.

What do the Delay and Amp cells actually do?

Normal cells spread to 4 neighbors after 1 beat, Delay cells wait an extra beat before spreading, Amp cells spread to all 8 neighbors, and Block cells stop the wave entirely. Routing through Amp cells while avoiding Delay bottlenecks is how you maximize coverage.

Is Spark Grid free to play?

HOW TO PLAY

Press Ignite, then tap exactly one open cell to launch the wave.
Normal cells spread in 4 directions after 1 beat. Delay cells wait an extra beat, and Amp cells spread in 8 directions.
Block cells stop the wave completely. Goal cells must all light up, and you also need to hit the coverage target shown above the board.
Each cleared board adds score and advances the round. One failed cascade ends the run.

TIPS & STRATEGY

You only get one ignition tap, so trace the wave in your head first — the chain spreads automatically and you cannot redirect it once it starts.
Amp cells spread in all 8 directions instead of 4, so routing the wave through an Amp cell is often the key to covering enough cells to clear the coverage target.
Delay cells hold the wave an extra beat before spreading, which can starve a far corner of coverage — ignite from a spot whose path doesn't bottleneck behind a delay.
You must light every Goal cell AND reach the coverage target in the same wave, so pick the ignition point that connects all goals rather than just the one that covers the most cells.

ABOUT

Spark Grid is a cascade-planning puzzle. Instead of tapping repeatedly, you design one ignition point and watch the whole chain unfold through blockers, delays, and amplifiers. That makes it feel different from straight logic grids: the fun is in predicting the automatic wave, not manually resolving each step.
