At the start of the game, each player receives 9 unknown cards and set up their Mine by placing them face down in front of them, in a 3x3 square. They flip the center card face up and the game can begin.
The goal is to fill the 9 slots of your mine with cards granting you the most points.
On your turn, you can play up to 2 cards from your hand. Play Gem cards in your mine – cards of your favorite color earns you points, as well as cards played on the right spot (each gem and Mine slot is numbered from 1 to 9). Use Adventure cards to your advantage to reveal, swap or steal cards in play and build the best Mine.
But beware: as soon as a Mine is entirely revealed, the game comes to an end and the player with the most points wins!
