Star Garden.

Put the indicated number of stars in every row, column and outlined region. Stars must not touch, even diagonally. Tap to cycle: cross → star → clear. Right-click or X marks empty. Arrow keys move; Enter or Space cycles. Red marks show rule conflicts, not whether a star matches the hidden solution. Each board has one solution and a verified deduction path.

Drag to repeat the starting mark across cells; the whole stroke is one undo.
