Star Battle & Region Puzzle Rules
Regionle is two daily logic grids that share one idea: place stars so that every row, column, and region has the right number, and no two stars touch, not even diagonally. This page is the short rule sheet for both. For a longer guide, see the region puzzle rules and the star battle puzzle page. To play today’s daily region puzzle, go to the home page.
The daily region puzzle (one star)
The home page opens on an 8×8 board with eight colored regions. Place exactly one star in every row, every column, and every region. Stars cannot sit in neighboring cells, including the diagonal neighbors. This is the day’s warmup, and it is the grid that keeps a streak.
The star battle puzzle (two stars)
The second daily grid, on the star battle page, is a 10×10 board with ten regions. The adjacency rule is the same, but every row, column, and region holds two stars. A three-cell region that must hold two stars is often almost fully determined: in a straight line, the ends are stars and the middle is empty.
Controls
- Tap a cell to cycle empty → cross → star.
- Drag across cells to paint crosses.
- Auto-X (on by default) fills neighbors and completed units. You can turn it off.
- Hint asks the server for one forced cell. It never returns the whole answer.
- Undo steps back one change. Clear removes your marks and leaves the timer running.
- The timer starts on your first mark and is used on the spoiler-free share card.
Streak, full clear, and the game day
Finish the one-star region puzzle to keep your streak. Finish both grids for a full clear. Progress is stored in this browser; no account is required. A new pair of puzzles arrives at midnight, America/New_York. The share card reports your time, whether you used a hint, and your streak — never the star positions.
FAQ
What are the two daily puzzles?
Each game day has an 8×8 one-star region puzzle and a 10×10 two-star star battle. Completing the one-star grid keeps your streak. Finishing both is a full clear.
How do I mark a cell?
Tap to cycle empty, then a cross, then a star. Drag across the board to paint crosses only. Auto-X, which starts on, fills neighbors and finished units for you.
When does a new puzzle appear?
At midnight in the America/New_York time zone. Every player receives the same pair of grids for that issue.
