7 Grid Up

Seven-Cell Battle is a minimal number puzzle: 7 cells, incoming number balls, add in a cell until the sum is 7 to clear it and trigger a chain (neighboring cells minus 1). Higher score shortens each turn; one wrong move can block the grid. Simple rules, tight tension, easy to learn and hard to put down.

Why play:
- Simple rules: sum to 7, chain clear, timed moves. Learn in seconds, play immediately.
- Short sessions: each game lasts minutes. Perfect for commutes, waiting, or a quick break.
- No forced ads: no full-screen pop-ups. You can optionally watch a rewarded video for an extra round after a game; you can also skip and still finish normally.
- Local only: scores, records, and streak days are stored on your device. No account or internet required.
- Privacy-minded: we only follow the system App Tracking Transparency prompt where relevant; other data stays on device.

For anyone who likes number puzzles, chain-clear satisfaction, and "easy to learn, hard to master" single-player games. No sign-up, open and play.
