Alongside the prize on every game, Ruby Bingo runs progressive jackpots — prizes that grow until somebody wins them.

Two nights carry one.

Wednesday's jackpot is won on a blackout — every square on your card — completed inside a target number of balls.

Here's the part that makes it interesting: the target starts at ball 48 and rises by one every week.

So in the first week you need your blackout within 48 balls. If nobody hits it, the jackpot rolls over, grows, and the following week you have 49 balls. Then 50. Every week that passes, the jackpot gets bigger and slightly easier to win.

Wednesday also doubles the prize on every game as the session goes on, so the night builds all the way to the end.

Thursday is the biggest night of the week, and its progressive works completely differently.

The jackpot climbs through the session, and it's won if any game or pull tab race ends on ball number 1.

That's it. It can land on any game, at any point in the night, including during a horse race. Nobody sees it coming.

Thursday also runs two blackout games worth 1,000 Emeralds each on games 5 and 6.

You don't have to do anything separately. If you're in the game, you're in the jackpot. Playing more cards gives you more chances at it, in the same way it gives you more chances at any prize.

The caller announces the running total during the session, and it's shown on screen. Because it rolls over week to week, the figure changes — always go by what's announced on the night.

Same as any prize. Credited to your account within a few minutes, and announced live on the stream.
