55 - The Calculator for "Stoppa"

55 is an app that I developed to challenge in a workday.
The application is developed in Swift and is available on the App Store.

The "stoppa" or "stuppa" is an Italian card game based on betting, in some aspects similar to poker, nowadays a little disused in northern Italy but still in vogue in the south, which was played starting from province of Bari up to all southern Italy. It is included among the prohibited games in public places.
