Delve deeper and deeper into a vast cave as you search for treasure in this mining game. The cave contains ten treasures, but with your digger, you won't be able to collect all of them just yet. You will need to take several mining trips to gather materials. Once you have materials, you can return to your base and sell the materials for coins, which you can then spend on upgrades. As you upgrade your digger, you'll be able to make longer trips.
