Unlimited rounds for signed-in players. Perfect your strategy before tackling the ranked daily puzzle.
Overview

How to play
- Tap cells to toggle black/white states according to the game rules.
- Unshaded numbers must be unique per row and column.
- All unshaded cells must remain orthogonally connected.
Strategy tips
- If three identical numbers sit in a row, the middle is often safe to shade.
- Watch corners — they constrain adjacency aggressively.
- Periodically zoom out to ensure the white blob is contiguous.
