While there have been some issues with gameplay and payouts, I don't believe Bingo Tour is a scam. However, players need to be cautious and informed about the potential risks involved in playing for real money.  Overall, Bingo Tour is a legitimate game app that offers a fun and potentially rewarding gaming experience.
It's not, so don't bother. Unless I get some sort of actual payout or prize for the HUNDREDS of ads I watched, I wouldn't come back to play any more. There is no point. If you want a game that actually pays out instantly to PayPal, Bubble Cash does.
