New educational game: Maths hide-and-seek

This is a new game where the Vedoques love to hide. But don't worry! They are leaving us clues to find them. The Vedoques are behind the correct answer.
We have three different activities. The first one works with adding numbers, the second one with the times tables and the third one, you use subtractions. To make it more interesting and encourage children, they can win our Vedoque Olympic Medals. If you can complete twenty sums without any mistakes you will win a gold medal. If you make up to 3 mistakes, you will get a silver medal and up to 4 mistakes, a bronze one. You can choose the level of difficulty on the front page of the game. There are 2 levels, in the easier level (6-8 years old), the sums are made with numbers from 1 to 10, in the harder one (8-11 years old) the sums are made with numbers from 10 to 100.
