3 × 3 TO START · ONE LEVEL TO EXPAND
Fabric · NeoForge · Singleplayer · Multiplayer
During an active challenge, death permanently deletes your inventory, equipped armor and offhand item by default. Nothing drops for you to recover. This is an intentional survival rule, not a bug.
Beim Tod werden während der Challenge standardmäßig dein Inventar, deine Rüstung und der Gegenstand in der zweiten Hand dauerhaft gelöscht. Es bleiben keine Gegenstände liegen. Das ist Absicht und kein Fehler.
Keep valuables in a chest. Purchased columns remain unlocked. Administrators can change the item rule with
/lb deathitems drop.
2.3.7 for Minecraft 1.21.1, 1.21.2 and 1.21.3. 3.0.4 for Minecraft 26.1, 26.1.2, 26.2 and 26.3. Separate Fabric and NeoForge files.
Border geometry is now cached per column and updated in small batches. Rendering work stays within the surrounding 3 × 3 chunks, reducing repeated calculations in larger areas. Distant purchases remain saved and protected. Local block changes still update the outlines. Large changes may take several frames to appear.
All 14 ports passed automated builds. Gameplay and rendering checks with additional mods ran on 1.21.1 and 26.1.2 with both loaders, including 250 and 1,000 unlocked columns. The other ports were not separately started in game for this patch. This is a targeted performance improvement, not a guarantee of a particular FPS with every modpack.
Deutsch: Die Grenzgrafik wird lokal zwischengespeichert und in kleinen Portionen aktualisiert. Entfernte Käufe bleiben erhalten. Die ausführlichen Spieltests liefen auf 1.21.1 und 26.1.2 für beide Loader. Alle übrigen Fassungen wurden in dieser Runde gebaut.
A tree just out of reach. A cave beyond the boundary. A route toward the End. In Level = Block, the space between you and your next goal has a price: experience.
You begin inside a 3 × 3 starting area. Gather XP and walk toward a reachable boundary. One full XP level purchases one new block column in that direction, across the entire world height. You unlock space in the existing world. You do not receive a block item.
Build a home, reach new resources or work toward defeating the Ender Dragon. Every expansion is a choice, and every level matters.
No setup commands are needed in a fresh world. Existing paused challenges stay paused. You can place and break blocks across the boundary, but movement remains restricted until you unlock the area.
| Feature | What it means in play |
|---|---|
| Shared territory | Explore the same unlocked area together while keeping personal XP balances and purchase milestones. |
| Three dimensions | Separate areas in the Overworld, Nether and End. Their starting sizes are 3 × 3, 5 × 5 and 3 × 3. |
| Persistent progress | Purchased columns, settings and challenge time survive restarts. Pausing does not reset the challenge. |
| Live XP display | The sidebar updates as your level balance changes. |
| Personal advancements | Milestones for 1, 10, 50, 100, 500 and 1000 purchased columns. Open them with L. They award no extra XP. |
| Terrain outlines | Borders follow terrain and partial block shapes above ground and in caves. Leaves do not change the border display. |
| Your colors | Choose separate border and outline colors. F12 toggles tall corner markers while block shape contours stay visible. |
| Boundary recovery | Spawn checks, bed recovery and seating protection help keep players in the unlocked area. Accidental escapes are corrected without killing the player. |
Bed placement is allowed on either side of the boundary. Waking and respawning are checked so you return inside the unlocked area. At an edge, sneaking without enough XP lets you lean out to build. If you have enough levels, expansion still costs XP.
The mod preserves normal terrain generation. It does not create floating islands or a separate Skyblock world.

Each Minecraft version has its own file. Match both the exact game version and the loader. Fabric and NeoForge files are separate alternatives.
mods folder.For a dedicated server, install the matching build on the server and every player's client. Everyone must use the same Minecraft version, loader and LevelBlock build. Singleplayer only needs your local installation.
Stop Minecraft or the server, back up the world, then replace the old LevelBlock JAR. Keep only one LevelBlock file installed. Existing paused worlds remain paused. Do not downgrade a world without a suitable backup.
Fabric 1.21.3 now uses 2.3.7 with the current gameplay and automatic start. The historical 2.3.3 for 1.21.3 is an older Beta that required /lb center followed by /lb start. Those manual setup steps are not needed for new worlds on the current releases.
| Command or key | Function |
|---|---|
/lb version |

/lb stuck or /lb bug |
Return to the starting area if you get stuck. |
/lb color <color> |
Change your personal border color. |
/lb outlinecolor <color> |

| L | Open Minecraft advancements with the default key binding. |
/levelblock and /lb are equivalent. Color names support English and German, including red/rot, blue/blau, green/grün and purple/violett.
These commands require cheats or OP permissions.
| Command | Effect |
|---|---|

Follow normal Minecraft death rules, including the keepInventory game rule. |

The deathitems commands replace the old /lb todesstrafe command. Choosing "drop" restores normal Minecraft behavior; it does not force item drops when keepInventory is enabled.
Du startest in einem 3 × 3 Bereich. Sammle Erfahrung und gehe an einer begehbaren Stelle über die Grenze. Ein vollständiges Erfahrungslevel kauft eine neue Blockspalte in deiner Laufrichtung, über die gesamte Welthöhe. Du schaltest Platz in der vorhandenen Welt frei und bekommst keinen Block als Gegenstand.
In einer neuen Welt startet die Challenge automatisch beim ersten Beitritt. Dieser erste Spieler legt das gemeinsame Startgebiet und den Weltspawn fest. Im Mehrspieler teilen sich alle die Fläche innerhalb derselben Dimension, bezahlen aber mit ihren eigenen Leveln. Gekaufte Spalten bleiben nach dem Tod und nach einem Neustart erhalten.
Beim Tod werden Inventar, Rüstung und Gegenstand in der zweiten Hand standardmäßig dauerhaft gelöscht. Nichts bleibt zum Einsammeln liegen. Lagere wichtige Gegenstände deshalb vorher in einer Kiste. Ein Administrator kann mit /lb deathitems drop die normalen Minecraft Regeln aktivieren. /lb deathitems clear schaltet die Inventarlöschung wieder ein. Dafür sind Cheats oder OP Rechte nötig.
Beende vor einem Update das Spiel oder den Server, sichere die Welt und ersetze die alte JAR. Installiere nur eine LevelBlock Datei gleichzeitig. Bereits pausierte Welten bleiben pausiert. In neuen Welten ist ab den aktuellen Fassungen kein manueller Start mehr nötig.
F12 schaltet die hohen Eckmarkierungen an oder aus. Konturen von Treppen, Stufen und anderen Blockformen bleiben dabei sichtbar. L öffnet die persönlichen Fortschritte. Die XP Anzeige rechts wird laufend aktualisiert. Mit /lb color <farbe> und /lb outlinecolor <farbe> passt du die Farben an.
Die normale Weltgenerierung bleibt erhalten. Die Mod erzeugt keine schwebenden Inseln. Baue deinen Weg aus, sammle Ressourcen und setze dir ein Ziel, zum Beispiel den Enderdrachen.
The September 2026 compatibility update, 2.3.6 for Minecraft 1.21.1 and 3.0.3 for 26.1.2, passed client gameplay, foreign block shape and nested passenger checks, normal world generation, and local dedicated server startup tests on both loaders. The October performance update builds on that work. Its separate validation scope is described above.
| Test environment | Mods loaded during testing |
|---|---|
| NeoForge 1.21.1 | Create, AE2, Mekanism, FramedBlocks, Farmer’s Delight, Supplementaries, Biomes O’ Plenty, Terralith, Jade, JEI, Sodium and Iris |
| NeoForge 26.1.2 | AE2, FramedBlocks, Biomes O’ Plenty, Terralith, Jade, JEI, Sodium and Iris |
| Fabric 1.21.1 | Rechiseled, Waystones, Traveler’s Backpack, Terralith, Jade, JEI and Sodium |
| Fabric 26.1.2 | Rechiseled, Waystones, Traveler’s Backpack, Terralith, Jade, JEI, Sodium and Iris |
Outlines now handle block shapes extending into adjacent cells and player dependent shapes. Movement checks include players in nested seats, even behind other passengers. Modpack authors can adjust the optional block tags levelblock:border_ignored and levelblock:border_noncolliding.
Tested together does not mean every feature is certified. Individual machine networks, moving Create contraptions, special teleporters, extra inventory systems and every shader were not fully tested. Iris was loaded without an active shaderpack. Iris on Fabric 1.21.1 remains unverified: that development test failed during remapping before world creation. The successful Fabric 1.21.1 tests excluded Iris. Install Iris and Sodium on clients only.
Deutsch: Die Schwerpunkte sind 1.21.1 und 26.1.2. Die vier Fassungen wurden mit den oben genannten Mods geprüft. Konturen berücksichtigen überstehende Formen und die Grenzsperre erfasst verschachtelte Sitze. Nicht jede Maschine und jeder Shader ist damit automatisch freigegeben. Die Iris Kombination auf Fabric 1.21.1 bleibt unbestätigt.
Create and Mekanism were available for NeoForge 1.21.1 in this test round. No matching 26.1.2 release was available for these two mods. NeoForge marks its loaders for 1.21.2, 26.1 and 26.3 as beta.
When reporting a problem, include Minecraft version, loader version, the result of /lb version, other installed mods and shaders, and the steps that reproduce it. Add a screenshot or relevant log excerpt when useful, after removing private information.
