ELI5: Explain Like I'm 5

Sim (pencil game)

SIM, also known as the pencil game, is a fun game that you can play with your friends. To play this game, all you need is a piece of paper, a pen, and some friends. Here's how to play:

Step 1. First, draw a big square on the paper. This square should take up most of the page.

Step 2. Next, inside the square, draw two smaller squares, one on top of the other. These squares can be any size, but they should be fairly small. They should also be centered in the big square.

Step 3. Now, draw a diagonal line through both of the small squares. Make sure the line goes from top to bottom and from left to right.

Step 4. Next, draw a small triangle on each corner of the big square. These triangles should point outward, away from the center of the square.

Step 5. Now you're ready to play! Each player takes a turn drawing a line from one corner of the big square to the other. The lines can't touch or cross any of the other lines. The goal is to be the last person to draw a line without trapping yourself in a triangle.

Step 6. If a player traps themselves in a triangle, they're out of the game. The winner is the last person standing who hasn't trapped themselves.

So, that's SIM! It's a fun and simple game that you can play with your friends.
