Super Memory Numbers

So I purchased this thing 3 or 4 times Still don't know exactly what it is I bought? Or how I can purchase it 3 or 4 times? And now it doesn't work at all - just keeps asking for more money. Uninstalled.

Good Training Sentence should be added for more difficulty

Don't buy Because you will keep on getting ads and the app will keep on nagging you to buy it again. The developers? They don't bother replying to your emails. Edit: They have replied , and basically they are telling me that I payed JUST to keep my score on the game I was playing? ...That's it? ... In other words, their game is a game where one buys its way up the leader-boards. Seriously! Is it supposed to make me feel smarter because I have change in my pocket? Anyway, their purchase system appears to be at least totally misleading if not just plain thievery , because Games are played to score and NOT to BUY score. Don't BUY! and, in fact don't bother even to install...One of the apps below does a much better job.

Don't buy What ever you do don't make the in app purchase. Because you will keep on getting ads and the app will keep on nagging you to buy it again, and the nagging is heavy ... The developers? They don't bother replying to your emails. So remember, don't buy, and better yet there are better choices out there. The post in Spanish bellow, says basically the same thing
