Free sandbox games give you a world and no instructions: build with blocks, craft tools, run physics experiments or play god over a tiny civilisation. Most here are block-building games rated Everyone or Everyone 10+, while two action sandboxes are rated Teen. WorldBox and Mini World: CREATA mention offline play.
A sandbox game is a box of toys with the lid off. Nobody tells you what to make, and that's either thrilling or slightly terrifying, depending on the player.
I chose ten from Google Play's most-installed sandbox titles and checked each listing for the developer, installs, ads and in-app purchases labels, the content rating and offline wording. Every one shows a Contains ads label. Their order is random.
Two very different things share the sandbox name. Most of these are calm building games in a blocky world, while Melon Sandbox and Payback 2 are about chaos, and both are rated Teen.

Ten sandboxes, each in brief

A 3D sandbox for exploring and building, with both an offline single-player mode and online multiplayer. Its listing says there's no grinding or levelling up.

Builders, gods and chaos merchants
- Block builders: Craftsman, Crafting and Building, World Building Craft, Craft World, Craft Building Block World 3D and Craft Build Block.
- Explore and create: Mini World: CREATA mixes building with adventure.
- God games: WorldBox hands you a planet and a set of creatures.
- Physics and action: Melon Sandbox and Payback 2 are about mayhem.
If a child loves building with bricks, the block builders are the obvious start. If they like stories and watching things grow, WorldBox is a fascinating little planet to look after.
Before a child starts building
Several of these mention playing with friends or other players, and all ten show a Contains ads label. Seven have in-app purchases, so turn on approval for in-app purchases on a shared device. Check the rating too: Melon Sandbox and Payback 2 are rated Teen, and four others are Everyone 10+.
From sandbox player to game maker
Plenty of children who love sandbox games end up wanting to make their own. If that's yours, my beginner's guide on how to make Roblox games is a gentle first step.
There's no wrong way to play a sandbox. Some children build the same house over and over, some knock everything down, and some just wander. All of it's play, and it's worth asking them to give you a tour of what they've made.
Open worlds with no signal
Only WorldBox and Mini World: CREATA mention offline play here. For older or smaller phones, these free offline open-world games for low-memory phones are worth a look. And if you'd rather build alongside someone in the same room, try these Android co-op games with mates nearby.
