From the Rules:

A uniquely interactive experience with Hawaii's ancient past.

The game's objective is to randomly draw Glyph stones from Glyph bags; place them on an identical image on the board; and create a continuous and uninterrupted line of Glyph stones. The winner of the game must, then, create a story based on the petroglyph images in their winning line.

Each player has a collection of 26 glyph stones. There are 12 different petroglyph images and the player will have 2 of each image and 2 blank (wildcard) stones.
