A great game to increase math ability and train the brain

Dear Hacker News community, my name is Gabriele Picco, I am twenty years and I currently study computer science at the University of Turin. I am computer enthusiast, I love to develop games and applications for smartphones. I just finished my latest work: "Number 777", a logic game that aims to train the brain while having fun. The trick is to make a sequence of successive sums that they meet the criteria, you win coming at 777. If you want to get an idea of the game here can see how it works: https://www.youtube.com/watch?v=T_evylWBsQo

It is available for all major operating systems:

IOS: https://itunes.apple.com/us/app/number-777/id1041325952 Android: https://play.google.com/store/apps/details?id=thundershotgames.number777 Windows Phone: https://www.microsoft.com/it-it/store/apps/number-777/9nblggh5xlvn

I would be most grateful if you could try and comment my game. Help me to spread a bit of my passion.

Thanks in advance for yours time.

Yours sincerely,

Gabriele Picco.
