Free application to identify the winning countries

When you open the application and click on start playing, the flags of the two countries that met in the Qatar League appear, as well as the result they obtained... What is required of me is to identify the two countries through their national flag and remember the winning country... Then write it at the bottom of the screen by clicking on the letters forming the name of the country Successive winner... If the answer is correct, I win 30 points, otherwise I am asked to think well and then correct by clicking on the wrong letter or letters to erase it and replace it with the correct one... If I do not succeed, I ask for help either with 10 or 15 points, or the full answer with 55 points. ..and I can't move to the next question except after answering the questions in order...a great app and requires you to have a mathematical culture...it's not difficult...try it...haha
