The POP Game

posted Dec 24, 2012, 4:54 PM by info nadstech


Pop as many balloons as your can!. 

Casual Game for all ages. Pop as many balloons as you can!

The order you pop them makes a big difference, make colour combos, double, triple, quad combos! Select the power ups you want and in the order you want to get the maximum score. Try to have the multiplier at max value all the time for maximum power up effects and points.

Beat your own record, beat your own achievements. Get all the dropping coins you can and buy new magics to pop more balloons faster than ever...

This is The POP Game.
Caution: It is very addictive.

As always the APP is ABSOLUTELY FREE for everyone. You can get it HERE

posted Oct 29, 2012, 3:43 AM by David Pellon   [ updated Dec 25, 2012, 5:49 AM by info nadstech ]

In one travel to Firenze with my wife we bought two music boxes and i really like them!.
I think they have some kind of special charm and like a lot their sound. For those of you that like to hear them along a very large collection of very beautiful and popular music, maybe just out of curiosity or to sooth your baby or any reason i have created a new android app called The Music Box (you can get it here)

The app has an alarm and a sleep timer. You can also select your favorites for easy access. Download it now and check it out :-)

Hope you like it, if you do please rate it and i will keep adding more songs.

We have a new game -> Maths Ninja !

posted Jul 4, 2012, 10:30 AM by David Pellon   [ updated Oct 2, 2013, 1:15 AM by info nadstech ]


I have just released a new game for everyone. Maths Ninja!. This is a fantastic game to practice your math calculation skills and also train your brain and keep it fast and sharp.

The game has different modes.
  • Arcade: where you will practice your maths under pression while being disturbed by a sneaky ninja that will throw you bombs and shurikens
  • Normal calculus: Just practice your math skills using this option
  • 1 error: Don't make the smallest mistake or you will fall under the claws of the ninja!

Also has different skill levels and math operations

  • Easy, Medium and Hard and Addition, Substraction, Divisions and more.

Maths are really important in real life for everyone of us. Even if you don't use maths frequently, practising and using your brain is good for everyone's mental health.


I really think your child and every one of you can benefit from this app training for some minutes a day. Your children will enjoy a lot playing a game, but more will enjoy you as their parent, knowing that they are practising their maths and they will be the fastests at math in their class.

The game its free of course. Just give it a try!


Please drop me a mail and tell me what you think!

Compare your math calculation skills with other players from all over the world.

As usual you can get it from the download section. Check the menu at the left of the page.
