''[[https://itunes.apple.com/us/app/junk-jack/id436555490?mt=8iOS Junk Jack]]'' mining game made by the PixBits that came out in November of 2011, inspired by Minecraft with a few nods to Terraria. A sequel, ''[[https://itunes.apple.com/us/app/junk-jack-x/id601584735 Junk Jack X]]'', came out on August 28, 2013, (incidentally the same day that Terraria iOS came out).

!!Junk Jack provides examples of:
* AcidPool: Generates on the surface of Xeno as well as underground on said planet.
* AdorableEvilMinions: Monkeys on Alba. Certain varieties will kill the player easily.
* AndYourRewardIsClothes: Certain mobs drop clothing items. {{Subverted}} because most of them provide useful abilities, like reduced lava damage, better luck, and extra damage dealt to mobs.
* HollyWoodAcid: Partially averted. Although it will kill the players when initially found on planet Xeno, the player can become immune to it with the right gear.
* LadderPhysics
* LavaAddsAwesome: You can use it as a light source, as a trap for other players in multiplayer, to kill mobs in your mob traps, as a method of transportation, etc.
* RainbowPimpGear: Much of the clothing is this trope.
* SerialEscalation: First, you go around punching trees to get wood. Then you build the first shelter and do some mining before cowering from the slimes, zombies, and spiders in your home in the night. Before long, you're traveling between worlds, coming up with traps to farm loot from mobs, making massive castles, and using lava to get around.
* {{Unobtainium}}: {{Mithril}}, Antanium, Titanium, and Galvanium.
* VideoGameCrueltyPotential: You can kill piglets. 'Nuff said.
