It's not just the odds — it's the payout

Roulette almost always gives you the better chance of winning. But because the bingo jackpot can dwarf your stake, its expected value per dollar can swing far higher (or lower) than roulette's fixed house edge. Tune the jackpot and watch.

What's actually on the board

Two real community bingo centres run on the same legal framework — yet advertise wildly different prize pools. Every figure below is read straight off a weekly flyer. Roulette games pay the winning number's value; the marquee jackpot is the night's headline.

The headline that almost never pays

The rolling-jackpot trap

A "$50,000 @ 40 calls or less" flyer dangles a life-changing number — but to claim it, a single card must complete all 15 numbers inside the first few balls. The maths is brutal, which is exactly why these jackpots roll over for weeks. Each ball in Australian housie is one of 90; a full house needs all 15.

Where every dollar goes

Victoria sets no fixed "percentage to charity" for bingo. Instead it brackets the money three ways: prizes must total 50–90% of takings over any 7 days; a bingo-centre operator may keep up to 60% of what's left plus a 2% fee; and whatever remains is the community organisation's. Slide the prize generosity and watch the charity's slice collapse.

Players win back Operator keeps up to Charity gets at least

Player's expected loss is simply the inverted prize return — here of every dollar staked. "Operator" is a legal maximum: real expenses can be lower, which pushes the slice to charity. A self-run session with no commercial operator skips that crimson slice entirely.

*Proceeds = takings − prizes paid (Act s 8.1.2). In a rolling-jackpot sequence the 60% is taken after the carried-forward jackpot contribution is set aside (Reg 77).

The flyer, decoded

Snowball
A progressive jackpot you must win inside a tight call limit. Nobody hits it → it grows and the limit eases next time.
Rolling-jackpot flyer
The big headline (e.g. $50k @ 48 calls). Includes a guaranteed in-house prize for the player who finishes after the limit, so the game always pays something.
Roulette game
Same odds as any game — but the prize is set by the winning number: 1–50 pays a flat $50, above 50 pays its face value. "Triple Roulette" = ×3.
Book · flyer · set
A book is a pad of tickets (one per game); a flyer is a one-off special ticket sold on top; a set is a discounted bundle of books.
PET
Personal Electronic Terminal — a tablet that auto-marks numbers. Capped at 10% of tickets in play under the house rules.
Full house
All 15 numbers on a ticket. Your chance of winning ≈ your cards ÷ all cards in play; ties split the prize.
