How to play
- Goal
- Give every territory one number from 1 to 4; territories touching by an edge or corner must differ.
- How it ends
- A chart clears when all territories are filled legally; there is no loss.
- Record
- Only the fastest first solve of each chart is kept; replays are practice.
- Give each outlined territory one number from 1 to 4, however many squares it spans. Two territories touching by an edge or a corner must have different numbers. Brass runes are fixed.
- In the worked picture, the two highlighted 2s meet only at a corner and clash. Change the lower-right rune to 3 so all four touching territories differ.
- Tap a territory to cycle its rune, or select it and tap a number below. Use Erase to clear it. Arrow keys move; 1–4 set a rune. Undo, Redo and Restart let you revise. Restart keeps the first clock running. There is no loss, and replays are practice.
