There is ore under your feet and that is a problem, because it is not in your pocket yet. Dig, sell, upgrade, hire auto-miners, keep digging.

<p class="bb_paragraph" >You have a pickaxe. There are about 3,000 meters of rock under your feet. You can see where this is going.</p><h2 class="bb_tag" >The hole</h2><p class="bb_paragraph" >Mining Miner is an incremental game about digging a very deep hole and refusing to stop. Every block sells. Every coin goes back into the digging. Eighteen layers of rock sit between you and the bottom, each one harder than the last. HOW FAR WILL YOU GO ???? (there is a bottom but I'm obviously keeping your attention)</p><p class="bb_paragraph" > </p><h2 class="bb_tag" >Stop digging alone</h2><p class="bb_paragraph" >At some point one pickaxe is not enough. Hire auto-miners that dig while you dig, and an elevator that hauls the ore up and sells it by itself. You never have to leave the hole again.</p><h2 class="bb_tag" >The skill tree</h2><p class="bb_paragraph" >Five branches: Mining, Auto-Miner, Elevator, X-Ray and Cartography. X-Ray shows ore through solid rock, which saves time, which means more digging. Cartography reveals caves before you fall into them. When progress slows down, Prestige resets the hole. You keep the bonuses and you dig it again, faster.</p><h2 class="bb_tag" >What's down there</h2><p class="bb_paragraph" >I don't know</p><h2 class="bb_tag" >The numbers</h2><ul class="bb_ul"><li><p class="bb_paragraph" >18 rock layers over ~3,000 m</p></li><li><p class="bb_paragraph" >46 achievements, Bronze to Diamond</p></li><li><p class="bb_paragraph" >28 languages to dig in</p></li><li><p class="bb_paragraph" >Full controller support (Xbox and PlayStation)</p></li></ul>
