How to play
This is bingo cut down to its bare bones. There are only 30 balls in the machine, and your card is a tiny 3 × 3 square of nine numbers. The left column always comes from 1 to 10, the middle one from 11 to 20 and the right one from 21 to 30, three different numbers per column. Nothing is free: all nine squares have to be called.
Before each game you pick 1, 2, 3 or 4 cards at 10 credits apiece and press the Play button, which shows the count and the cost (for example “Play 2 cards (20)”). From then on the machine runs by itself. A ball drops every 0.8 seconds, any matching square on your cards is stamped for you, and the prize rows above the cards update as soon as something is won.
Two prizes are on offer in every game:
- Line: three in a row on one card. On a 3 × 3 card that means any of the three rows, any of the three columns or either diagonal, so a card has eight ways to make it.
- Full house: all nine numbers on one card. When it falls, the game is over.
Your cards are not alone. Another 36 cards, played by the computer, sit in the same hall and chase the same two prizes. If you want to look at a near miss, Pause stops the draw and Resume restarts it. Faster cuts the gap between balls to about a fifth of a second, and Draw all runs straight to the end. Close the page mid-game and it reopens paused on the same ball.
Why 30 balls plays so differently
The small ball count changes everything about the rhythm. Each of your cards holds 9 of the 30 numbers, which is almost a third of the machine, so from the very first ball there’s a real chance it lands on your card. In a few hundred test games with two player cards in a hall of 38, the line went on the 5th or 6th ball on average and hardly ever later than the 10th. The full house came at around the 21st ball, somewhere between the 15th and the 26th, which means most games end with only a handful of balls left in the machine.
At normal speed that’s less than half a minute from first ball to full house. If you want a longer evening with the same idea, 75-Ball Bingo uses a 5 × 5 card and usually needs more than 60 balls before anyone fills it.
Ties are far more common here than in the bigger games. With 38 cards each covering nearly a third of the balls, about one game in three ended with two or more cards making the line on the same ball, and roughly one in four had a shared full house.
Prize money
Ninety per cent of everything spent on cards in that game, yours and the hall’s, forms the pot. The line takes 30% of it and the full house takes 70%:
| Your cards | Cards in the hall | Pot | Line (sole winner) | Full house (sole winner) |
|---|---|---|---|---|
| 1 | 37 | 333 | 99 | 233 |
| 2 | 38 | 342 | 102 | 239 |
| 4 | 40 | 360 | 108 | 252 |
When several cards complete a prize on the same ball, it’s split evenly between them and your share is rounded down to a whole credit. If two of your own cards tie, you collect both shares.
Strategy
There’s nothing to decide once the balls start, so the honest advice is about money, not tactics.
Every card in the hall has the same chance at every prize, which makes the long-run return easy to state: each card gets back 90% of its price, minus a hair for rounding. Playing four cards instead of one makes you win more often, but you also pay four times as much, and on a 3 × 3 board your cards bump into each other often enough to split prizes with themselves. The return per card doesn’t move.
What you can choose is the pace. With 1,000 starting credits and 10-credit cards, a single card per game lets you play a very long session, while four cards burns through the bank about four times as fast for the same average result. Faster and Draw all don’t change any outcome; the ball order is fixed the moment you press Play.
