I have signed up for www.nipsapp.com and created the account on the website. I have purchased several packages from them, because they offered great variety of games. After that I started to get more and more offers from the moderators, who pushed me to buy other packages. I have agreed and after some time I faced a lot of problems with the apps, because almost all of them were defective and I couldn’t open them.
