Recently Ruined

I used to love this app. It was simple and easy to just open up and play sudoku as much as I wanted. Recently they have added a timer of 2:30 minutes after each game unless you “upgrade.” You are out of your mind if you think anyone is gonna sit there and wait over 2 minutes for something that used to be free and you’re even more of an idiot if you think anyone is going to pay to get rid of this wait that you have added. I’m done with this app just go buy a sudoku book or get any other app out there. It’s sudoku you didn’t invent it and you’re certainly not the best at it to be making these ridiculous changes.
