Grid Reactor

Grid Reactor is a portrait block puzzle built for quick sessions and long score chases. Pick one of three shapes from the tray, tap a legal cell on the board, and watch completed rows and columns disappear in a clean flash. Chain clears to push your score higher and keep the board breathing.

Four ways to play keep the loop fresh. Classic mode is the pure score attack. Reactor mode adds a charge meter—fill it with smart placements, then tap REACTOR PULSE to wipe pressure off the grid in one satisfying burst. Daily mode seeds the board from the calendar day on your device, so everyone gets the same puzzle date, but you can replay it anytime. Puzzle Lab holds a focused scenario for players who like planning several lines ahead.

Eighteen distinct placement shapes rotate through the tray, so you are always balancing odd footprints against tight corners. Unlock five board themes as your best scores climb; they change the look of the grid without touching the rules. Achievements track milestones across modes, and the statistics screen keeps your personal records in one place.

Sound, music, haptics, and reduced motion can be toggled in settings. A short tutorial on first launch explains placement in plain language. Progress, preferences, and unlocks stay on this device through local save—no account required for the core game.

If you enjoy tidy clears, combo thinking, and a sci-fi glow on every block, Grid Reactor is ready when you are. Learn the tray rhythm, respect the edges, and see how far you can push the reactor before the grid closes in.
