Drill Overview

A game where you upgrade your drill to dig through the ground. 1. Stage Start After the stage begins, an upgrade option with 3 choices will appear shortly. Choose wisely and clear the stage. 2. Stage Clear Upon clearing a stage, you'll be forced to watch an ad. The reward is 400 coins. I found it bothersome, so I closed and reopened the game. There's also a clear reward chest on the main screen. 3. Roulette Use the collected coins to spin the roulette and upgrade your drill. Review Cleared up to stage 5 and then uninstalled.
