Bingo Terminology: The Complete A-Z Glossary
Online bingo has its own vocabulary — a mix of traditional bingo terms, gambling industry jargon, and chat room shorthand. This glossary covers the key terms you'll encounter, from the mechanics of the game to the bonus terms in the small print.
New to online bingo and confused by the lingo? Here's every bingo term you need to know, from auto-daub to wagering requirements. Plain English, no fluff.
A-C
Auto-Daub
Software feature that automatically marks off called numbers on your bingo card. Most platforms enable this by default. Recommended for online play — you'll never miss a number. Some players prefer manual daubing for the hands-on engagement, but auto-daub is the safer choice for beginners.
Auto-Buy
An option on some bingo platforms that automatically purchases tickets for the next game when the current one ends. Useful if you don't want to manually re-enter each round. Can be set for a fixed number of tickets per game.
Bingo Card / Bingo Ticket
The printed or digital card used to play bingo. In 90-ball bingo, a card has 9 columns and 3 rows with 15 numbers and 12 blank spaces. In 75-ball bingo, it's a 5x5 grid with 24 numbers and a free space in the centre. "Card" and "ticket" are used interchangeably.
Bingo Strip
In 90-ball bingo, a strip is a set of 6 tickets sold together. Each strip contains all 90 numbers exactly once. Buying a full strip guarantees that every called number marks off at least one cell across your six tickets. Not more expensive than buying 6 individual tickets.
Buy-In
The cost to enter a bingo game, usually the price per ticket. Can range from 1p in penny rooms to £1 or more in premium rooms. Some rooms have a minimum buy-in (e.g., "minimum 5 tickets").
Chat Host
The person (or automated system) that manages the chat room during a bingo game. Chat hosts keep conversation going, run mini-games, and award bonus prizes. A good chat host significantly improves the social experience of online bingo. They also enforce chat room rules and can ban players who break them.
Chat Room
The live text chat alongside the bingo game. Players chat, joke, congratulate winners, and interact with the chat host. A key part of the social experience that differentiates bingo from solitary casino gaming.
D-G
Daubing
Marking off numbers on your bingo card as they're called. In physical bingo, done with a dauber (stamp or marker). Online, either automatic (auto-daub) or by clicking/tapping each number.
Deposit Bonus
A bonus offered when you make a qualifying deposit. Typically a percentage match of your deposit (e.g., 100% up to £50). Subject to wagering requirements before winnings can be withdrawn. Also called a "welcome bonus" when offered to new players.
Free Space
In 75-ball bingo, the centre cell of the 5x5 card is a "free space" — it counts as marked without a number being called. This gives you a head start on completing patterns. 90-ball bingo doesn't have free spaces.
Full House
The completion of all numbers on a bingo ticket — the top prize in 90-ball bingo. For more detail, see our 90-ball bingo guide. In the broader sense, "full house" is also used in chat to celebrate big wins.
H-L
Jackpot (Progressive)
A prize that grows over time as tickets are sold. Unlike fixed prize pools, a progressive jackpot accumulates until someone wins it. Often requires a full house within a set number of calls (e.g., "full house in 45 calls or less"). Can reach thousands of pounds.
Line
In 90-ball bingo, winning calls are: one line (any complete row of 5 numbers), two lines (any two complete rows), and full house. The line prize is the smallest of the three, two lines is medium, full house is the jackpot.
M-R
Maximum Bet / Maximum Tickets
The upper limit on tickets you can buy per game. Some rooms cap the number of tickets per player to keep competition fair. Common limits are 6, 10, or 20 tickets per game.
Pre-Buy
Purchasing tickets for an upcoming bingo game before it starts. Most online platforms allow pre-buying tickets for scheduled games in advance. Useful if you want to secure tickets for a popular jackpot room.
Prize Pool
The total prize money available in a bingo game, shared between the winner(s). In some rooms, the prize pool is fixed; in others, it grows with ticket sales (progressive). The prize pool is displayed before the game starts.
RNG (Random Number Generator)
Software that generates random numbers to determine which balls are called in a bingo game. All UKGC-licensed online bingo operators must use certified RNG software, independently audited for fairness. This ensures the game is unpredictable and fair for all players.
S-Z
Side Games
Mini-games or slots available to play alongside a bingo game. Common on most online platforms. Quality varies — some are genuinely engaging, others are filler. Side games often include fruit machines, scratch cards, and puzzle games.
Speed Bingo
A faster-paced variant of bingo where numbers are called more rapidly. Cards typically have fewer numbers. Popular for players who want a quicker game. Games can last just 1-2 minutes.
Ticket
See "Bingo Card / Bingo Ticket." The terms are interchangeable.
Wagering Requirements
A multiplier applied to bonus winnings before you can withdraw. Under UKGC rules (post-2024), operators cannot impose more than 10x wagering on bonus winnings. For example, if you win £20 from a bonus, at 10x wagering you must wager £200 before you can withdraw. Always check the T&Cs.
Welcome Bonus
An introductory offer for new customers, typically a deposit match plus free games or spins. The value varies significantly between operators. Some welcome bonuses include a no-deposit component — see free bingo no deposit.

The main menu area where you browse and select bingo rooms.

VIP / Loyalty Scheme
