Café Noir and Midnight Express are both Blackout Bingo Rooms! This means that the patterns needed for a Bingo are different from the regular Rooms - such as needing to fill your entire card to claim a Mega Bingo! To help facilitate claiming Mega Bingos in these more challenging rooms, there are also more calls than usual.
