Players will take turns placing their sharpened chisels onto lines around the hex tiles, which are laid out in a single slab. Once a section of the slab is broken off from the rest of the rock hex tiles, it is divided up among the players who helped contribute to the break. Broken off tiles are assembled by the players who collected them into various dinosaur fossils, with varying point values. Once all of the tiles have been collected by players, the totals of all the completed fossils are tallied up with the highest score winning!
