Luma: Star Battle

Can you find the last two stars? Solve 240 offline puzzles with hints that explain why, then watch each answer light a new constellation.

Discover Star Battle, the logic puzzle where stars cannot touch. Restore a celestial atlas across 240 original puzzles, with clear help whenever you need it.

PLACE EVERY STAR

Place the required number of stars in every row, column and colored region. Stars cannot touch, even diagonally. Use marks and deduction to reveal the only solution. Boards grow from 5×5 to 9×9, moving from one-star rules to two-star challenges.

A COMPLETE PUZZLE JOURNEY

Travel through two volumes and eight lightly told story chapters: Lantern, Compass, Swan, Crown, Observatory, Tide, Comet and Aurora. All 240 puzzles are included and available offline. Progress and unfinished boards are saved on your device.

HELP THAT EXPLAINS

Start with a guided tutorial. Unlimited hints explain the next logical step before changing the board. Check rule conflicts without revealing the answer, undo any move, and choose whether completed rows, columns, regions and cells beside stars are marked automatically.

DAILY PICKS, NO PRESSURE

The Observatory chooses one puzzle each day from the existing 240-puzzle atlas. Catch up on the last seven days and discover 16 trophies as you play. There are no streak penalties or time limits.
