The basic objective of Moonstone is to have more, well, moonstones than the enemy by the end of Turn 4. Moonstone placement is generated by taking seven d4s into your hand and pouring them onto the middle of your board from some height. Once they land, they'll represent moonstones, with the number showing how deep they are. It takes one energy to pull a moonstone a level.
