Description by Patoli Studio Written by the developer, not by AppBrain. Click to read.
This is a simple blackjack game we made for an interview one time.
While we want to release this game with our unique touch in the future we think it is an engaging game as it is so we decided to share it with everyone here. It took us 4 days for development and 2 for planning (design UML diagrams).
