How to play
90-ball is the bingo of British halls and European living rooms, and its ticket looks nothing like the square cards of the American game. It’s a long strip of 3 rows by 9 columns. Each row holds exactly five numbers and four blanks, so a ticket carries 15 numbers in all, and every column has at least one. The columns go by tens: the first holds 1 to 9, the second 10 to 19, and so on until the last, which takes 80 to 90. Within a column the numbers run from smallest at the top to largest at the bottom.
Pick between one and four tickets at 10 credits each and press Play. Balls are called automatically, roughly one every 0.8 seconds, and every number you hold is daubed for you. A counter under the latest ball reads “Ball 34 of 90” and so on, and the three prize labels above your tickets fill in as each prize is claimed.
Use Pause and Resume to stop and restart the caller, Faster to speed it up and Draw all to skip to the end. If you close the page, the game picks up later on the same ball, paused.
Three prizes, one row at a time
Only horizontal rows count in 90-ball. There are no columns or diagonals, and no shapes. The prizes climb in a strict order:
- One line: any one row of five complete on a ticket. 20% of the pot.
- Two lines: two complete rows on the same ticket. 30%.
- Full house: all three rows, all 15 numbers. 50%, and the game ends.
The ticket that wins one line doesn’t have to be the one that wins two lines, and two rows split across two of your tickets don’t count. A row of five out of ninety balls is a slow build, so the early part of the game is quiet. Over a few hundred test games with two player tickets in a hall of 38, the first line went at about the 34th ball, two lines at about the 57th and the full house at about the 70th, nearly always between the 55th and the 80th. Ties were rare for the one-line prize (about one game in twenty) and somewhat more common for the later two, at around one game in ten.
Pot and payouts
Ninety per cent of what every ticket in the hall cost goes into the pot. A typical game with two of your tickets and the 36 house tickets has a pot of 342 credits, so a lone winner gets 68 for one line, 102 for two lines and 171 for the full house. Buy four tickets and the pot becomes 360: 72, 108 and 180. Tied winners share equally, rounded down to whole credits for you.
Strategy
Like every bingo, this one leaves you no decisions after you buy. The useful thinking happens before the first ball.
Each ticket covers one sixth of the 90 numbers, and every ticket in the hall, yours or the computer’s, is drawn up the same way, so they all have the same chance at each prize. Over many games, each one gives back 90% of its price. Rounding your shares down takes a sliver more.
Buying more tickets raises how often you collect, not how much each ticket returns. With four tickets you’re 4 of 40 in the hall instead of 1 of 37, and you pay four times as much each game. Pick the number that suits how long you want your 1,000 starting credits to last.
Because three prizes split the pot, a single game is less all-or-nothing than the two-prize 75-Ball Bingo. If you like the 90-ball ticket but want to mark the numbers yourself and race a family to call “Tombala!”, try Tombala, which uses the same ticket layout with no credits at all.
