We are a group of students who play mobile games on our smartphones and love it. But the most frustrating part? We can't transfer in-app purchases to other games. What if I spend $5 on a game but don't use all of it? It would be super-efficient if we could transfer in-app currencies.

We created Sandbank: a platform for the standardization of in-game currencies across mobile games. Our universal in-app currency is called, Clippies.

​

Mobile game companies can use Clippies as their in-app currency by connecting via our API.

End users download our Sandbank app, sign in via Google, and then can easily purchase Clippies. The user can see all the supported apps that use Clippies.

Then, once a user wants to play games on their phone, they can buy in-app purchases with Clippies on any game or mobile app. It's now extremely efficient for users to buy and spend in-app currency.

Mobile game companies will want to use Clippies as their currency because of the visibility we offer for them on our app. Users can see new games and apps they might not have seen before, hidden deep in the app store. It also creates a sense of legitimacy for these apps.

Mobile game companies are featured on Sandbank for free. To incentivize them to use Clppies, the company makes 60% off of each Clippie spent in their app.

We built our prototype on Adobe XD. We are looking forward to building out the actual app.

There 1.28 Billion mobile game users. In-App purchases account for 48% mobile app earnings, worth 37 Billion but only 5% of users do in-app purchases. If we make it easier for in-app purchases, we could increase the percentage of mobile game users who do buy in-app and increase how much the current users do purchase.
