Lone Crown: Star Battle Logic

Place one crown in every row, column and color. 500 levels and a fresh daily puzzle, each with exactly one answer you can find by logic.

Place one crown in every row, every column and every color region. Crowns may never touch, not even at the corners. That is the whole rule set, and it is enough to keep you thinking for hours.

Every puzzle in Lone Crown has exactly one answer, and you can always reach it by logic. You never have to guess.

500 LEVELS Start on small 5×5 boards and work your way up to tough 9×9 grids. A solver checks every level before it ships, so the difficulty climbs steadily.

A NEW PUZZLE EVERY DAY The daily puzzle is the same for everyone. Solve it each day to build your streak. Missed a day? Open it later from Past puzzles.
