How to Set Up a Game of Sim

Draw a Dots in a Hexagon Shape.
On your paper, draw six dots to form the points of a hexagon. If you choose to, you may connect each dot to each other with a connecting line; this is great if you or another player struggles to visualize the connecting lines between each dot that you will need to draw. It is not necessary however, you only need the six dots.
How to Play SIM
Players take turns drawing lines in their color, connecting two unconnected dots together.
Your goal is to avoid drawing a triangle where all three sides are formed with lines of your color.
Rules for Triangles
Only triangles formed using the hexagon’s outer points count. It is possible that you may create a triangle in the middle of the hexagon by crossing previously drawn lines. These triangles do not count towards a loss, only triangles formed by their three sides, each in your color, connecting to outer dots.
Winning (by not losing)
Continue drawing lines connecting the dots around the hexagon. The first player to form a triangle loses.
