This a math and word game together. Word databases are turkish.

Please play firstly with your friends (for online game)

What is problems?

1- Ads problem. All sections have minimum 1 math+1 word game. ıf user pass the games, player will see result screen.

On result screen there is an "watch and earn" button. Player can increase earning points by watching this reward ad.

But now system doesnt work. Player watch ads but doesnt earn point or coin.

2- On menu there is a list. Rules-How Play and Privacy Policy has same design. Basic text pages.

But 2 of them doesnt work. I think, text is there but text same color as background. Because scrool bar is working.

I want a lots of changing but firstly i need to solve these problems.

My budget 70 dollars for this project.

If you cant make it on this budget, dont give me offer.
