This is a multiplayer pencil-paper game, which is kinda like dots and boxes but more complex. It's a fun-sized party game made for people to use strategy and creativity. You draw a large shape on a piece of paper to set up the game, then the players take turns drawing lines. Not only are there multiple different types of lines that you can draw, but every line must start at an angle but end at a line or another angle, without overlapping another line. When a person draws a line that player has to put down a tally mark near their name outside of the shape. The first to get 30 tally marks gets eliminated and then the other players can continue on that shape or start a new one without the eliminated player(s), the last one standing wins. But if you make a triangle on your turn you have to go again until you lose or don't make a triangle.
This is the short version of the official ruleset that I have right here, https://drive.google.com/file/d/18t2rtogqkLto6LAeFWSPNFCCLt5...
