Goal
Draw rectangles on the grid so every cell belongs to exactly one room — and each room contains exactly one circle.
●
●
Circles are your clues. They tell you where rooms must reach.
How to Draw
Tap & drag from one corner of a room to the opposite corner. Lift your finger (or release the click) to lock the room.
Or simply tap two cells to define a rectangle between them.
●
Two completed rooms shown above — each contains exactly one circle.
Rules
• Every cell must belong to exactly one room (full coverage, no gaps, no overlaps). • Every room must contain exactly one circle. • Rooms are rectangles — any size from 1×1 to N×N.
Tools & Stars
Undo removes the last room. Clear wipes the board. Hint (3 per level) flashes a correct room.
