Star Battle Puzzles

About Star Battle Puzzles

Star Battle Puzzles is a free browser site built around one grid logic puzzle. The board is divided into bold regions, and you place stars so that every row, every column and every region holds the required number, with no two stars in neighbouring cells, diagonals included. On the daily 10x10 board that number is two.

The daily is published at midnight US Eastern and is the same for every player. If you miss a day, it stays in the archive at a permanent link dated to its day. The site says each board is generated and then checked by a solver so that it has exactly one solution reachable by deduction, so there is always a next move to find.

You tap a cell once to mark it with an X, twice for a star and a third time to clear it, and you can drag to paint X's across cells. An optional Auto-X marks the cells a new star rules out, and an Errors toggle shows mistakes. Progress saves automatically, and a timer runs while you play.

Beyond the daily, the library has one-star 5x5 and 8x8 boards for beginners, two-star 10x10 boards and three-star 14x14 ones for long solves. It suits LinkedIn Queens players who want the harder two-star format, since Queens is in effect a one-star Star Battle.

Tips

• Small regions often have only a few legal spots for their two stars; start there.
• When two regions fit entirely inside two rows, those rows' stars all belong to them: cross out the rest of the rows.
• Turn on Auto-X so each star clears its eight neighbours for you.
