💡 Grid Blackout Guide
Grid Blackout is Mintford's logic district: a neighbourhood block has lit up by accident, and every tap on a house toggles its own light and its neighbours'. Turn the entire block dark, in as few moves as you can manage. It looks calm. It is not.
| Grid Engineer rank | Best score |
|---|---|
| ⚡ Night Electrician | 3 |
| ⚡ Grid Engineer | 8 |
| ⚡ Chief Engineer | 15 |
How the game works
Tapping a house flips that house and the houses directly above, below, left and right. Lit becomes dark, dark becomes lit. The block is cleared when every house is dark. Each level generates a fresh, always-solvable pattern, and clearing it advances you to a slightly larger or trickier block — your level count is your score.
Controls
One input: tap or click a house. That's it. The puzzle is entirely in deciding which house.
Scoring and the Grid Engineer career
Your score is the highest block you have powered down, so the tiers read like level gates: 3 (Night Electrician), 8 (Grid Engineer) and 15 (Chief Engineer). Unlike score-based districts, there is no compounding — level 15 is simply fifteen separate puzzles deep, and every one of them must fall.
Beginner mistakes
- Tapping lit houses. Your instinct says to hit the glowing thing. The puzzle says the glowing thing is often fine and its dark neighbour is the real lever.
- Random tap chains. Taps cancel each other in pairs — every house tapped twice equals no tap. Panic-tapping literally undoes itself.
- Not finishing rows. The standard technique works row by row; jumping around the grid loses the plot.
- Giving up on level 5. Levels 3–5 are where the grid stops being trivial. Everyone feels stupid there; the ones who slow down pass it.
Advanced strategy
- The chase-down method. Work top to bottom: for each lit house in row N, tap its mirror in row N+1. When you reach the bottom row, the remaining pattern tells you which top-row cells to tap first — memorise the small set of bottom patterns and their first-row answers.
- Parity is your friend. Because double-taps cancel, the order of your taps never matters, only the set. Think in sets, not sequences.
- Restart cheap. If a bottom row comes out ugly, restart immediately — a doomed board costs minutes, a restart costs seconds.
- Practise the 5-wide bottom rows. Levels past 10 mostly differ in how the bottom row resolves; that is where all the study value is.
Frequently Asked Questions
Are the puzzles always solvable?
Yes. Every generated block is created by applying random taps to a dark grid, which guarantees at least one perfect solution exists.
Does move count matter for score?
Your score is the level reached, not your efficiency — but efficient solving keeps you mentally fresh for the later blocks.
What's the fastest way past level 8?
Learn the chase-down method properly. It turns Grid Blackout from trial-and-error into a procedure, and level 8 becomes a formality.
Why did my taps seem to do nothing?
You tapped houses you had already tapped. Taps commute and cancel in pairs — check whether you doubled a corner.
