Are you thirsty for an idle-click game? Mine Upgrade is available to satisfy your demand! Wow! A number of gripping features are just ready to be unveiled! Let's go without any hesitation, please!
There is a cheerless cave, where treasures were buried deep underground. Just setting foot into the place, every player has a chance to mine many types of materials, from coal, rock, gold, ruby, to platinum, emerald, and more. So, what's mainly to do here? Like other idle game episodes, you're merely requested to use the mouse to click on such the resources non-stop. At the end, money will be accumulated. To sharpen the process of mining, making deals on advanced upgrades is also a must. The more you tap on the items, the more materials you will discover. It's up to you to decide whether to sell any unnecessary mineral or not.
Give Mine Upgrade a chance and you won't regret later, I bet! Play for fun!
