Sandbox games hand the design work to the player, which sounds like less work and is actually more. The build tools have to be genuinely pleasant to use, because they are the game — clunky placement or a bad camera will end a session faster than any missing feature.

The other half is sharing. A creation nobody sees may as well not exist. Saving, loading and showing off builds is what turns a building toy into a community.

The core loop

Gather or unlock materials, build something, show it to other players.

We plan your sandbox game around this loop first, then our 10+ AI-skilled developers build every system it needs.

What we build

What goes into your sandbox game

These are the systems a sandbox game lives on. They're part of the build, along with a shop, saving and game passes.

1

Placement tools

Snapping, rotation, deletion and undo. Undo is not optional.

2

Material progression

Blocks and parts unlocked by play, giving structure to an open format.

3

Save and load

Multiple build slots per player that survive rejoins.

4

Showcase space

A gallery or plot system where others can visit what you've made.

5

Anti-grief boundaries

Clear ownership so nobody can edit or destroy another player's work.

What we design around

What kills a Roblox sandbox game

No undo

Building without undo is stressful, and stress is the opposite of what this genre sells.

Builds that don't persist

Losing a two-hour creation is the last session that player will have with your game.

No audience for creations

Building for nobody gets old. A gallery or visitable plots is what sustains the loop.

After launch

Launch your sandbox game with creators

Sandbox games grow through build showcases and challenge videos, which give creators effectively unlimited content from a single install.

BLOXG is also the marketplace where those creators get hired. Browse sandbox creators or read the sandbox marketing guide for what works in this genre.
