Mine cases: fill out the Skyblock!

About Mine cases: fill out the Skyblock!: Open Chests, Collect Mobs, Fill Your Island

Mine cases: fill out the Skyblock! puts a floating Skyblock island in front of you — starting with nothing but a regular chest and a handful of free blocks. The goal is to fill that island by opening chests, collecting mobs, and arranging them however you like. A floating green grass island with a blue water pool and white waterfall edge sits centered against a light blue background in several views of the game.

Every mob pulled from a chest carries one of four rarity levels — blue, purple, red, or gold. The higher the rarity, the harder it is to obtain, but the greater its coin value. Mobs aren't just collectibles: leave them on the island and they'll bounce around and produce their own unique sounds. Arrange them freely to create an island of chickens, an island of creepers, or any combination you are able to dream up. One scene shows a large dark chest with purple bat-like wings and yellow eye-like markings resting on the grass.

The collecting loop runs deep — the full challenge is assembling the entire collection and truly filling out the Skyblock.
