Some Ruby Bingo games start with a wild — a rule that marks a whole set of numbers off your card before the first ball drops.

It's a head start. You'll see squares daub themselves the moment the game begins, and you haven't done anything yet.

Before the game starts, the caller announces the wild. Every number on your card matching that rule is marked off automatically.

There are two kinds.

Last-digit wilds. The wild is a digit from 0 to 9, and every number on your card ending in that digit gets marked.

Example — "Ends in 5" Every number ending in 5 is daubed: 5, 15, 25, 35, 45, 55, 65, 75. On a typical card that's several squares gone before the first ball.

Letter wilds. The wild is a column — B, I, N, G or O — and that entire column is marked off.

Example — "G" The whole G column on your card is daubed.

There are also Odds and Evens wilds, which mark every odd or every even number on your card.

Wilds make games faster and closer. Everyone gets the same head start, so more players end up one number away at the same time — which is exactly when a session gets loud.

You'll see wilds most often on Fast Money Mondays, where there's a wild on nearly every game alongside 5-second ball drops. That combination is what makes Monday the quickest night of the week.

No. Wilds are applied automatically to every card in the game. Just watch your card light up and get ready — with a wild in play, bingo can land a lot sooner than you'd expect.
