Evaluation
Cubic Castles is a free-to-play massively multiplayer online game that has been live since August 13, 2014. The game is built around a persistent online world with an in-game currency (cubits), a cubit store for purchasing items, and player-driven economies and communities — a structure that is designed to run as an ongoing service indefinitely.
A significant development occurred on August 14, 2026: a news post revealed that the game has changed ownership, with a new entity called Raptisoft Nova now running the game. The new owner (posting as "Zachalack") stated that "more updates will be coming soon to fix bugs and issues with the steam version," confirming that the game is still actively supported under new management. This is the most recent developer communication and it points to continued operation and upcoming work on the game.
Evidence
New owner (Raptisoft Nova) posted an update announcing a branding change to reflect new ownership, and stated that more updates are coming soon to fix bugs and issues with the Steam version.
Store description references an in-game currency (cubits) that can be earned through gameplay or purchased, a cubit store, and customizable cosmetic items — hallmarks of an ongoing live online service.

About this game
3D Platforming Meets Open World Voxel Building!
Cubic Castles is an online game where you build worlds from cubes and other items. What kind of worlds? Anything you want! Role playing, 3D-platform gaming, or other challenges! What you make is up to you. Want to make a punishing parkour with slippery ice and deadly spikes? No problem! Or maybe a simple house on a hill overlooking a lake? That's easy too! Even after only a few days the open beta saw players create many fantastic and varied worlds!
Features:
Massively multiplayer in one large, persistent world.
You share the world with everyone! Find a plot of land, put a castle down, and start creating!
Super-playable 3D Platform Action
Cubic Castles operates with a fixed camera that you control, and the gameplay is anything you want it to be, from action platforming to artistic design.
Customizable Characters
Create your own unique look with hats, shirts, plants, glasses, and more!
Mining Resources
Mine resources in a variety of world biomes including forests, arctic wastelands, deserts, mountain ranges, and tropical islands, all with different resources you can use. More to come!
Intuitive Crafting
Just drag your raw resources and tools into a workbench to see what you can build.
Crazy Obstacles
Accelo-rings, mechanical spikes, quicksand, lava, warp doors, and tons more!
Generous Economics
Forget the grind! Our pricing is fair and reasonable. And cubits even pop out for free as you mine.
Active Community
We just launched the open beta, and already there’s a very active, vocal community. And we're listening!
