Play-to-earn games reward gamers with digital cash or non-fungible tokens. In recent years, these blockchain-backed games have gone mainstream. They have become a core component of nearly every metaverse out there, with each platform boasting its form of cryptocurrency to pay online gamers for their time commitment.

Earning cryptos that have real-world value while having fun is one of the main reasons why play-to-earn games have become so popular. 

This guide will look at the best three games to earn free crypto. These play-to-earn games offer different features, from the rewards you can earn — crypto and NFTs, for example — and gameplay innovations.

Let’s dive in.

Sandbox

The Sandbox is a play-to-earn blockchain game that allows players to build a virtual world using non-fungible tokens (NFTs) on the Ethereum blockchain.

Players can design their avatars to access the different games, environments, and hubs on The Sandbox metaverse. You can think of the game as a DeFi version of Minecraft on the blockchain.

Launched in 2011, the Sandbox was initially a mobile gaming platform intended to rival Minecraft. Instead, it became a hit and generated more than 40 million downloads worldwide.

But in 2018, the co-founders Sebastien Borget and Arthur Madrid decided to explore the potential of creating a 3D metaverse on the blockchain. They aim to let users own their creations as NFTs and earn rewards while participating in the ecosystem.

The new Sandbox project was released in 2020 and became one of the fastest-growing games in the crypto world, along with Decentraland and Axie Infinity.

Sweatcoin

Sweatcoin is a fitness platform that leverages the Move-to-Earn (M2E) model by allowing users to convert physical movements into digital currencies. As users move around, they generate SWEAT tokens, which they can use to buy products,  donate to charities, or convert to other cryptos.

The Sweatcoin platform was established in 2016 by Anton Derlyatka and Oleg Formenko. Initially, it was a platform that incentivized people to move around. The founders were passionate about promoting physical fitness; hence, they created a system that motivates its users to work out.

Users who achieve a certain number of steps consistently receive tokens, which they can use to exchange for cryptos or prizes.
