everything you do now has an ad and when you try to click out it forces you to open up the app download page. the ads literally full page open up and you're forced deal with them and then this company says the ads company controls the size but thats a lie. you control if they get a banner which was fine or a massive pop up. dont respond telling me there's a no ad paid version either because there's a thousand free chess games just like this one. The devices back button does NOT close the ad!!
