- Number eight on the brain-game shortlist (docs/brain-game-roadmap.md)
- It never says which way is better — it counts both, the squares in the shape and the rectangles you used
- The fewest-rectangles figure is an exact search, not a heuristic, because the board claims it and the claim has to be true
- 360 shapes generated and checked: one connected piece, 10–34 squares, and a true minimum between 2 and 5 rectangles
- Tap two corners to place, tap again to remove; rectangles cannot overlap or spill outside the shape
- A real-world mode: how many tiles for an L-shaped roomplanned
✓ = done · ☐ = planned. Every game is built one step at a time like this.
