Hold on to your hard hat and start digging in this entertaining mining puzzle game. Collect the three crystals on each level while avoiding enemies and spikes, and keeping companions safe. And if that weren't enough, you've got to do it all with a limited number of moves. Can you make it to the exit alive?

Improving its UI and crafting system while adding new worlds and creatures to contend with, this sequel to 2012's hit Motherload-esque mining simulation takes you to all new alien planets as you control a lost robot scrounging for supplies to repair and upgrade himself in a wide variety of ways.

A little robot is lost and alone in the galaxy after being crippled by a radiation wave... but hope isn't lost yet. Travel to a series of remote planets and dig for valuable resources in this mining game, searching for everything you need to finally find a way back home. Fans of Motherload will find a lot to appreciate here, with a gorgeous presentation and a few new elements dressing up the familiar gameplay.

Who says robots never get to go on adventures? In this short but addictive little casual mining simulation, you play a small robot with a big drill who is out to rebuild the city by bringing in ore to sell. While not as complex as other mining titles, Utopian Mining is cute, accessible, and a lot of fun for an afternoon.

Just over two years ago from this day, a relatively unknown indie programmer called Notch posted about a work-in-progress version of a sandbox building game on the TIGSource forums. It was called Minecraft, and at the time, people thought it was really very cool. Fast forward to the present and Minecraft has sold over four million copies, been through extended alpha and beta phases, spawned the Mojang indie studio, and gained so much popularity, the launch of its official version took place at a Las Vegas convention dubbed MineCon. That's an impressive feat for any game, let alone one started by a single person. But now, Minecraft is officially out. No more beta, no more alpha, it's here. Time to lose yourself in a voxel world all over again!

Recently, we've seen a bit of a mini-renaissance of quality casual releases set underwater, defying the conventional wisdom that games get terrible when they go down the drain. Fisher Diver, an action game by Eli Piilonen, keeps the quality but darkens the tone. On its surface, it's a retro-styled fishing game about a little ball that hopes to follow in it's father's profession. However, like the ocean, there are some unsettling things to be found below the surface.

Scuba is a 2D, side-scrolling game of exploration, diving, mining, and crafting in the tradition of Minecraft and Terraria. Control your diver-character as you collect 10 types of resources above ground and underwater. Combine items in your inventory to craft parts that will eventually help you make an engine to get home. Scuba's random world generation gives you a different game environment each time you play.

Mega Miner is a mining game that's all about repeated trips to the underground that challenge you to balance your fuel levels and item capacity for maximum efficiency, all so you can make your drill-bot the best it can be. There's something wildly addictive about unearthing gems, and let me tell you, one hip cat to another, I dig it. Can you dig it?

You like Dino Run SE, right? And Nanotube? Well, imagine a game that's nothing like either of those games but co-created by the makers of each. Imagining that? Now stop and check out Super Space Rubbish, a game that satisfies the wildest fantasies you've had since starting this review, and does so with a fantastic retro style. Super Space Rubbish looks a lot like the classic Asteroids game on the surface, but really it's a mining/upgrading sort of experience where you customize your ship using materials extracted from asteroids smashed with your turret.

Minerbot features a distinctive minimalist art style that might be confusing for the first couple runs. Once you get into the groove of the game, though, there's definitely an addictive quality to watching a collector hollow out a massive expanse of ore. The action's accompanied by a hopping techno soundtrack.

Sometimes, a game goes through such a metamorphosis during its development cycle that it's practically a different product from its original release. Thus is the case with Minecraft, a little old building game, inspired by Infiniminer and Dwarf Fortress, and created by Markus Persson. Whether you can only play it for fifteen minutes at a time, or end up devoting hours at a stretch (often unintentionally) to it, Minecraft is intensely enjoyable, and an incredible bargain. Minecraft Beta will be out on December 20th, so this is your last opportunity to get the game at Alpha pricing and with the promise of all future updates for free.

XGen Studios is behind this Flash game that is reminiscent of the old-school arcade games Dig Dug and Boulder Dash. Hired to mine the dangerous planet of Mars, you are given a robotic mining pod and sent off on a mission to bring home the Motherload, a fabled cache of rare and valuable minerals. Dig far below the surface of the Earth to earn money for upgrades and find treasure.
