Back of the Box:

Stake your claim! It's gold fever, and you want to have the best patch of land in these gold-filled hills.

Roll the dice to claim an area as your own. Steal claims from other players, or double your claim to make an area permanently yours.

You can keep rolling as long as you want, claiming more and more land on each roll. But watch out: If you make a bad roll, you lose all the land you claimed this turn! End up with the biggest patch of land, and you win!
