The Game of Sim: Paper and Pencil Game

The Game of Sim is a paper and pencil game played by two players, Red and Blue, using six dots ('vertices') arranged in a hexagon. This is a digital file with 100 pages ready to play. Players alternately draw a line between two dots. The first player to draw a triangle of their color between three dots loses.

The game cannot end in a tie. 15 moves is the maximum. If the game actually lasts 15 moves then the loser will actually complete two triangles at once!
