Players are ice fishing Inuits. Players punch holes through the 'ice' (a sheet of paper) and try to catch fish, represented by steel balls of various sizes. Big fish are worth more than small, and the fisher with the most points at the end of the game wins.
Reference sheet useful for quick referencing and provides a structured summary for teaching the game.
See the At the Gates of Loyang game entry if you are interested in ref sheets for other games that I’ve made. If you do not have Microsoft Powerpoint, a PDF version is also available there.
