A strategy game by Patrick Callahan inspired by the four color theorem.
- 2 players
- 2 pens/pencils
- 1 piece of paper
- Players decide on a number (any number over 4 works, but a number between 10 and 20 is recommended).
- Players take turns drawing lines, adding one shape each to the map until the number of shapes on the map equals the number decided in the previous step.
- Shapes must all be connected (no islands).
- Players take turns adding the numbers 1-4 to a section of the map, while keeping to the following rules:
- Like-numbered sections must not touch, but may share a corner.
- All numbered sections are forever marked, and may not be changed.
- If a player finds that they cannot place a number without breaking one of these rules, then they lose the game and their opponent wins.
- If neither player loses, then the game is a tie.
