Contracts

Contracts are what Levels are to RPGs. When you Complete Contracts, you unlock Shovels and HeadLamps in the shop as well as HeadStarts. You even get a health boost. So with all the new stuff you'll have something to spend all that hard earned gold. Approximately every 10 levels there are new Shovels and HeadLamps, while new HeadStarts are every 3 levels. So keep checking back at the shop to find out whats new. Another incentive to complete contracts is that the drops (including Gems) improve in quality the higher your contract. In the case of Gems, every 50 Contracts increases your Gem Bonus by 1x.

To complete the requirements for Contracts, firstly dig to a certain depth and then have in your possession the set of gems. You can check what is needed at anytime by going to Menu > Contract. If you have already reached the required depth and have the gems on hand, a dialogue will popup to let you know that you can complete the Contract.

Additional Tips
 * You can complete your contracts at any time, or several at one go. Given that they give a health bonus, you can save them and complete your contracts when you are low on health.


 * You could even complete contracts during a Danger Zone to have an extra chance at succeeding.
