1. Draw a large rectangle with smaller numbered boxes (1–10 or 1–13).

2. Players take turns flicking bottle caps, progressing through boxes in sequence. Eg: If you successfully throw a cap in the first box, you can attempt the second one. If the cap falls outside, you begin from box 1.

3. One can continue attempting the next box as long as they manage to land their bottel cap inside the boxes. The next players turn arrives when someone misses the box.

4. Upon reaching the last box, they become a killer. Killer can hit others to eliminate them.

5. A player wins by completing the full route or being the last one remaining.
