I have just released Trade Arena to the iOS and Android stores.
The game is a mixture between sports and the stock market. You're basically buying & selling digital cards of event outcomes, for example, Spain wins the UEFA European Championship in 2024. If that outcome comes true, you will receive a certain amount for each card you're holding. If it doesn't, you will not receive anything and the card is worthless.
It's free to play, you're not playing with your real money but with points, which are limited and you can't buy more.

Edit: I have completely revamped the UI since I did not like the "old" design anymore.
