About the game
Three pieces wait in the tray. Drag each one onto the 8×8 reactor grid: fill a row or a column and it bursts. Clear lines on back-to-back moves and the combo climbs, x2, x3, x4, multiplying every clear while the reactor glows hotter. Empty the whole grid for a Grid Burst jackpot. There's no rotating, so every piece needs a plan, and the run ends when nothing left in the tray fits.
Play a classic run any time, or the Daily Puzzle: everyone gets the same pieces today, and a streak counts the days you come back. Beat your best to unlock new reactor themes. This is an early access build: scoring and the piece mix will be tuned from real runs, and updates will land here as they're done.

How it’s built
- Pure HTML5 Canvas and vanilla JavaScript: no engine, no build step.
- No art files at all: every glossy block is drawn in code with gradients and highlights.
- Each tray comes from a seeded generator that searches for a full placement on your board before dealing it.
- Every sound is synthesized in the browser at runtime, the same way as the other Labs games.
