Starloom: Star Battle Puzzle

A new Star Battle every day: 8×8 on weekdays, 10×10 on weekends. Hints explain each step, and every solved level lights a star in one of 12 constellations.

Starloom is a Star Battle puzzle set under a night sky. The rule fits on one line: one star in every row, every column and every colored region, and no two stars may touch, not even at a corner. When the last star lands, the board fades and your stars join up into a small constellation of their own.

TWELVE CONSTELLATIONS, 25 STARS EACH The 300 levels are grouped by constellation, from Cassiopeia to Orion. Every solved level lights one of a constellation's 25 stars on your sky map, and the figure takes its real shape as you go. Boards start at 5×5 and grow to 10×10.

HINTS THAT NAME THE REASON A hint never places anything for you. It highlights the cells that matter and states the deduction in one sentence, such as "A star here would leave the highlighted region no room, so this cell stays empty." If a star you placed isn't part of the solution, the hint tells you that first. The first hint on each puzzle is free; each extra hint costs one short video.

ONE DAILY PUZZLE A new 8×8 board every weekday and a 10×10 on Saturday and Sunday. The calendar keeps your streak and lets you go back to days you missed. Watch one video to keep a streak shield ready; it covers a single missed day.

AT YOUR OWN PACE No clock runs on the board while you play. Your time appears only after the last star, on the result card and in Stats. Leave a board halfway and every star and mark is waiting when you come back.

ON THE BOARD • Tap once for a mark, twice for a star, or switch to Star first in Settings • Drag across empty cells to mark them in one stroke, and undo any move • Auto-mark: place a star and its neighbors, row, column and region dim out (you can turn it off) • Every puzzle has exactly one solution, reachable by logic alone • Dawn and Night themes and optional color-blind patterns; with Reduce Motion on, the star and win animations are skipped • Share a card with your time and hints, never the solution • Every level and daily puzzle is stored in the app, so you can play without a connection • English, German, French, Spanish, Italian, Brazilian Portuguese, Turkish, Japanese and Korean

WHERE ADS SHOW UP Starloom sells nothing; Google AdMob ads pay for it. A banner sits at the bottom of the home, board and sky-map screens. A full-screen ad can appear only when you tap Next between numbered levels, never after the daily puzzle. You won't see one during your first five levels on install day or after a level solved in under 20 seconds; two of them are always at least two levels and 90 seconds apart, and there are no more than ten a day. Settings has an Ad break: watch one video and banners and full-screen ads stay away for 30 minutes.
