Voxel Block Builder [PETS]

Voxel Block Builder [PETS] is a creative sandbox game on Roblox where players place voxel blocks, mine terrain with a pickaxe, and save their work to persistent private worlds. Developed by verified studio Goober Labs and launched in June 2025, the game has accumulated over 83 million visits and nearly 5 million favorites in under a year - a favorite-to-visit ratio of around 6% that is far above typical sandbox norms and reflects strong bookmarking behavior from younger players.

The core loop is open-ended building: open your inventory, select a block type, and click or tap to place it anywhere in the world. Swing the Pickaxe to mine and reclaim existing blocks. There is no objective to meet or timer to beat - the game hands you a world and lets you build whatever you can imagine. The [PETS] suffix marks a companion expansion layered over the core builder, adding collectible pets as a secondary system. Personal Worlds function as private save slots, so each player's creations persist across sessions without interference from other builders:

• 🏠 Building - Free-placement voxel construction with a growing weekly block roster
• 🗺️ Blue Dimension - Gamepass-unlocked alternate world for building in a distinct environment
• 💎 Rainbow Block Pack - Gamepass set of vibrant colored blocks for decorative builds
• 🏠 Colored Glass Pack - Transparent colored blocks that open up new architectural styles
• 🚗 Fly Ability - Premium movement unlock letting you build and explore from the air

Goober Labs commits to weekly block additions, which keeps the inventory growing steadily. The Bombastic Pickaxe gamepass replaces the default mining tool with a faster premium variant, and 2x Sprint Speed makes traversing large builds quicker.

Voxel Block Builder sits in the same creative-sandbox space as Voxel Sandbox, with the pets layer and weekly update cadence giving it a more live-service feel than most static block games.
