This app is called PopStellar. You can earn here free XLM (Stellar Lumens) by tapping or popping boxes with the same color that are grouped together. The mechanics of the game is similar with CryptoPop and CryptoRize. If you are still confused about how to play the game, check out my articles about those too.
To start earning, download PopStellar on play store then sign-up using your Coinbase email. They only accept that wallet as of the moment. During the game, you have to reach the required points to advance to the next stage. It's very easy and you can earn a maximum of 30,000,000 Stroop or 3 XLM!
Minimum amount to withdraw is 100 Stroop. And trust me, their payment is instant. You will immediately receive it to your Coinbase account. You can only withdraw every 3 days though to avoid spam.
