Sim
Rules
The game starts with six dots/vertices.
The first player, on their turn, draws a blue line between two dots that do not yet have a line drawn between them. The second player, on their turn, draws a red line between two dots that do not yet have a line drawn between them. An edge between two dots may not be drawn or colored twice.
A player loses when they create a triangle whose sides are all the same color. Specifically, this triangle must be one whose vertices are three of the six original dots; any triangles with a vertex that is an intersection of two drawn lines that is not one of the original six vertices does not count.
In the above example, the player drawing blue lines loses because they created a triangle whose sides are all blue.
Variants
- Misere: The objective is to complete a triangle of your own color before your opponent does.
- Heptagon: Each player colors edges of a 7-vertex complete graph.
