Dots And HexagonsLogic Level 5
Imagine you were playing a two-player game that involves each player taking turns draw a dot on one of the vertices of this graph. The rules for where a player can draw a dot are as follows:
A player can only draw a dot on a vertex that has not already been drawn on.
A player cannot draw a dot adjacent to another dot.
The game ends when a player is unable to place another dot. What is the minimum number of dots that can be placed in one complete game?
Bonus: can you generalize this for all other centered hexagonal boards?
