# SandBox

**SandBox :** <https://www.sandbox.game/en/>\

**Before we tell you about Yuugen Island, you need to know what SandBox is.**

## The SandBox

The Sandbox is a community-driven platform where creators can monetize voxel ASSETS and gaming experiences on the blockchain. Sandbox main mission is to successfully introduce blockchain technology into mass-market gaming. The platform focuses on promoting a creative play-to-earn model that allows users to be both creators and players. The Sandbox leverages the power of blockchain technology by introducing the SAND service token, which facilitates transactions on the platform.\
\
Users can **monetize** their time on the platform:

* **Selling ASSETS**: Users can create and sell ASSETS on the [marketplace](http://sandbox.game/en/shop) as NFTs.
* **Owning a LAND**: Buy a LAND in one of the [LAND sales](https://opensea.io/collection/sandbox). Players can then rent them or populate them with content to increase the LAND's value.
* **Building Games on the Game Maker**: Build and monetize games using the [Game Maker](https://www.sandbox.game/en/create/game-maker/) on the LANDs that are owned by players.

## SAND Token

SAND is the utility token used throughout The Sandbox ecosystem as the basis for transactions and interactions. It is an ERC-20 utility token built on the Ethereum blockchain. There is a finite supply of 3,000,000,000 SAND.

## **What is LAND**

A LAND is a digital piece of real estate in The Sandbox metaverse that players can buy to build experiences on top of. Once player owns a piece of LAND, the player will be able to populate it with games and ASSETS. Multiple LANDs can be combined to form an ESTATE.

A total of 166,464 LANDs will ever be available, contained in a map that will form The Sandbox metaverse.

GEM and CATALYST defines the tier, scarcity, and attributes of ASSET. CATALYST adds empty sockets to the NFTs that can be filled with GEMs. The higher the quality of the CATALYST, the more sockets your ASSET will have.
