Slot games that never pay out

Some slot games just never seem to pay out. "The Dark Knight" by Microgaming has a super low RTP at 88.12%, so good luck hitting anything decent. "Mega Moolah" might have a massive jackpot, but regular wins are almost nonexistent. "Sushi Bar" by Betsoft? You’ll be spinning forever, waiting for a payout that never comes. If you’re looking for frequent wins, avoid these ones.
