The goal of the game is to collect the three different types of rocks, Igneous, Metamorphic and Sedimentary. You do this by going around and around the game board. In the process you will choose Cobblestone Cards and filling in your Rock Record Cards.
The first player to collect all three cards and have a completed Rock Record Card wins!
The game board has a whole middle section that focuses all on changing states. There, rocks can be melted, receive heat and pressure or be broken apart through various methods.
A tip for the Rock Record Cards- I laminated ours and used dry erase markers with them because the rocks are frequently changing form!
