How to play
Multiplier Ball is a quick bingo round with a game-show finish. You don’t daub anything yourself; the game marks every card as the balls come out.
- Choose Cards (1, 2, 3 or 4) and a Bet per card of 1, 2, 5, 10 or 20. The Play button shows the total, for example Play (20) for four cards at 5.
- Press Play. Twenty balls roll onto the rail above the cards, and matching squares are marked as they arrive.
- Then one, two or three multiplier balls follow. Each is a normal numbered ball from the same drum, but it also carries a multiplier, ×2, ×3, ×5 or ×10, and it marks squares like any other ball.
- Each card is paid on how many lines it completed and whether a multiplier ball sits on one of those lines.
A card is a 5×5 grid of 25 numbers with no free space in the middle. The first column holds numbers from 1–10, the second from 11–20, then 21–30 and 31–40; the last column draws from 41–51. Lines are the five rows, the five columns and the two diagonals, twelve in all.
Your cards stay the same from round to round. New cards deals a fresh set of four whenever you feel like a change.
Pay table
Pays are per card, as multiples of the bet on that card:
| Lines on the card | Pays |
|---|---|
| 1 | 3× |
| 2 | 9× |
| 3 | 40× |
| 4 | 200× |
| 5 | 1,000× |
| 6 or more | 5,000× |
Lines are counted, not just the best one. Two lines crossing at a shared square pay 9×.
Multiplier balls
The number of multiplier balls is random each round: one ball 60% of the time, two 30%, three 10%. Each one’s multiplier is drawn separately: ×2 45% of the time, ×3 30%, ×5 17% and ×10 8%.
A multiplier only counts on a card where its number lies on a completed line. A multiplier ball that lands on a square of the card but not on a finished line does nothing, apart from marking the square. When two or three multiplier balls each sit on completed lines of the same card, their values multiply: ×3 and ×10 make ×30 on that card’s whole win. The ball does not need to be the one that completed the line; it just has to be part of it.
A card shows its result in its footer, such as “1 line ×5: +75”.
The odds
Because every ball is equally likely, it doesn’t matter which numbers a card holds, only which of its 25 squares end up marked. The game’s own test enumerates all 2^25 marked/unmarked patterns of a card and combines them with the draw and the multiplier balls. The exact return is 96.18% per card.
Some figures from the same count, per card per round:
| Result | Chance |
|---|---|
| No line | 88.7% |
| At least one line | 11.3% (about 1 in 9) |
| Exactly two lines | about 1 in 160 |
| Three lines | about 1 in 4,100 |
| Four lines | about 1 in 124,000 |
Without the multiplier balls, line pays alone would return only about 44%. More than half of the game’s return comes from multipliers landing on completed lines, which is why the round often feels quiet until those last balls.
Strategy
- Card choice doesn’t matter. All cards have the same chances, since only the pattern of marked squares counts. New cards is for variety, not luck.
- Cards versus bet size. Four cards at 5 and one card at 20 cost the same and have the same 96.18% return. Four cards give you about four times as many single-line hits and fewer empty rounds; one big card swings harder. Pick the rhythm you like.
- Read the round from the rail. After twenty balls you can see which cards are one square away. That doesn’t change the odds, but it tells you which card the multiplier balls could boost.
- Know the realistic ceiling. A single line with a ×10 multiplier is 30× the card bet, and that happens now and then. Four or more lines on one card is a once-in-a-very-long-time event.
