⛏️ OneBlock Java – 17 Phases, Sulfur Caves & Tiered Gear (26.2)

Start on one single block and mine your way through an evolving world — now with a real gear progression and six brand-new biome phases.


🌳 Gameplay

You begin on one block in the Overworld. Every block you break pushes the phase counter forward. Each phase brings its own block pool, resources, structure fragments with matching loot, and biome-specific mobs.

Gear now progresses in order. Plains gives you copper. Sunflower Plains gives you iron. Dark Forest gives you diamonds. No obsidian, no lava anywhere before phase 4 — you'll be searching for both long after you've got your diamond gear, same as the imaginary difficulty curve of a real playthrough.

7,850 blocks stand between you and the endless Void.

🗺️ The 17 Phases

Plains → Sunflower Plains → Dark Forest → Jungle → Cherry Grove → Snowy Plains → Savanna → Swamp → Desert → Badlands → Lush Caves → Sulfur Caves → Deep Dark → Trial Chambers → Pale Garden → Deep Ocean → The Void

🌋 Sulfur Caves — and a working geyser

The newest biome in the game, built straight from its own vanilla biome definition. Sulfur, cinnabar, their polished and brick variants, sulfur spikes, a Sulfur Cube resident — and a rare 3-block geyser: magma block, reactive sulfur, water on top. Scoop the water with a bucket to mine it, just like the real mechanic.

🌡️ The world actually changes with you

Every phase tags the ground around the block with its real vanilla biome. Snow falls in Snowy Plains. Water tints green in the Swamp. Fog, sky color and ambient sound shift with every transition — this isn't cosmetic paint, it's the same system vanilla biomes use.

🔥 Nether & End — no island, same as the original

The Nether is empty — just an endless Nether OneBlock. The End has no island: step through the portal and the Ender Dragon is already waiting over nothing. You mine your own footing from the End OneBlock and fight it without a safety net.

📊 On-screen info

A sidebar tracks phase, blocks mined, blocks left and a progress bar — no visible sort numbers, just the numbers that matter. A floating tag appears above the block during every transition, showing the next phase with a live countdown.
