At the end of each exercise points are distributed: Plus points for each correct answer, minus points for every wrong and a time bonus. From certain scores bronze, silver and gold trophies are awarded. The scores of each exercise are stored in the highscores.
The exercises are really well explained and understood before the first time. Then comes a countdown, so you can prepare yourself mentally and off you go. The exercises begin easy and become heavier with every correct answer. After wrong answers wid the difficulty automatically reduced, so that you again have a chance - very similar to the GMAT test at some business schools.
The exercises appear at first glance really simple, partly really turn out under time pressure but as tricky. The rest are in demand and concentration.
At the start of the game you have to create a profile, under the personal results will be stored. You can also create multiple profiles, so the whole family can practice separately from each other with the app. Switching between profiles is simple and intuitive.
There is also still a "hot-seat" -Mehrspieler mode.
The graphics are well done and the background music is not to complain about - and if need quickly issuable. Not 100% good - Unfortunately, the performance of the app - at least on the Kindle Fire HD. In between I had from time to time hanger of two or three seconds. That's pretty annoying when one by running in the middle of the practice time at a task. This brings one again to a new high score. For this, I subtract a star.
Otherwise, I am very satisfied with the app. I had been thinking for some time, me to buy full price app. That there is now a free app of the day, the better. Now I know: the app is also its regular price worth. A buy recommendation!
