FEMTO: Follow Up

Follow-up to the February Game Rules of FEMTO.


Stage: 4 Challenge Level: Challenge Level:3 Challenge Level:3 Challenge Level:3

This is a game for two players. You need the game board shown below. It is easy to draw if you want to play this on paper. You will need two different colour pencils (highlighters are good to use).

The dots are towns. The 9 straight lines are roads going to and through the towns.

Each player takes a turn to colour over a whole straight road (even though it may pass through several towns).
The first player to colour three roads going to or through the same town wins.
