How to play
- Goal
- Draw two perpendicular arms from each circle whose lengths multiply to its number.
- How it ends
- Complete every circle without shapes sharing a grid point; unused dots are allowed and mistakes can always be undone.
- Record
- The fastest first unaided solve of each chart is recorded.
- Every circle starts exactly one horizontal and one vertical straight arm. Each arm has at least one segment.
- Multiply the two arm lengths to match the circle’s number. Count spaces between dots, not the dots themselves. A blank circle has no fixed product.
- Different shapes cannot share any grid point, including endpoints and another circle. Unused grid points are allowed.
- Select a circle, then select an endpoint in its row and an endpoint in its column. Selecting a new endpoint replaces just that arm.
- Clear removes one shape; select its circle when lines overlap. Undo and Redo change one arm entry. Restart keeps the first clock running.

Tips for Kakeeru
- Factor the clue A 4 can use lengths 1×4 or 2×2. Reject factors that cannot fit the grid.
- Use blocked dots An endpoint used by another shape rules out that direction.
- Leave spare dots You do not need to cover the whole grid.
Questions about this game
Do lengths count dots?
No. Count grid segments, the spaces between adjacent dots.
Can shapes share an endpoint?
No. Different shapes may not share any grid point.
Does Restart reset the clock?
No. The first clock keeps running. Replays after a finish are Practice and preserve the first time.
Arm entries and Undo save in this browser. The first clock starts when a chart is selected. Reloaded attempts stay local; replay is Practice and preserves the first finish.

About Kakeeru
Draw an L from every circle, using factor pairs and occupied dots to find its two arm lengths. Different shapes must remain separate.
The 96 charts and worked diagrams are original. Four open shelves run from 4×4 to 7×7 dot grids.
