What is lockout bingo?
Lockout bingo is a competitive bingo format in which every player shares one board, and the first player to claim a square locks it out for everyone else. Because no square can ever be completed twice, the game stops being a race of luck and becomes a contest of route planning, speed and denial.

The three rules that define the format
One board is shared by every player, rather than each player holding a private card.
Claiming a square immediately removes it from play for all opponents â that is the lockout.
A player wins by completing a line, or by holding the most squares when the timer expires.
How a lockout match plays out
Every player sees the same grid of objectives from the moment the match starts. When you finish an objective you claim its square, it turns your colour, and it is gone for everyone else. That single rule changes the whole shape of the game.
- Early game: players spread out and take the objectives that suit them, avoiding contested squares.
- Mid game: lines start forming and players begin claiming squares specifically to block an opponent.
- End game: the remaining squares are the hardest ones, and the winning line is usually decided by who can deny rather than who can complete.
Lockout versus race scoring
Lockout is one of two ways to run a shared board, and the difference matters when you are choosing a format for a group.
- Lockout: squares are exclusive. Best for competitive play and for small groups who want direct interaction.
- Race: players work the same board in parallel and squares are not exclusive, so the winner is decided on completion time. Better for large or asynchronous groups.
- Both formats use the same cards, so you can run a board either way without rebuilding it.
Board sizes and objective counts
A board is a square grid, so the number of objectives a card needs grows quickly with its size. A card must hold at least as many objectives as the board has squares.
- 4x4 needs 16 objectives â a short match, usually under half an hour.
- 5x5 needs 25 objectives and is the standard competitive size.
- 7x7 needs 49 and 9x9 needs 81 â long-format boards for events and marathons.
- Free-centre and diagonal win conditions can be toggled per match.
What you need to play
Lockout bingo needs nothing beyond a browser. One player hosts a match, shares the join code or link, and everyone else joins from whatever device they already have.
- No install, no account, and no cost to host or join.
- Up to 10 players per match, plus unlimited spectators on a watch link.
- Timers, rerolls and colour-locked claims are built in, so no external bot or plugin is needed.
- Dedicated pop-out and overlay views for streamers who need the board readable on a broadcast.
Lockout bingo questions
What is the difference between lockout bingo and normal bingo?
In normal bingo every player has a private card and marks numbers as they are called, so two players can mark the same number and nobody interferes with anyone else. In lockout bingo all players share one board of objectives, and claiming a square removes it from play for everyone else. Normal bingo is a game of chance; lockout bingo is a game of speed and denial.
How many players do you need for lockout bingo?
Two is enough for a head-to-head match, and the format holds up well up to about ten players. Larger groups usually run better as a race, or as a bracket of smaller lockout matches, because a single board gets claimed out very quickly with a big field.
How long does a lockout bingo match take?
It depends on the board size and the objectives on it. A 4x4 board of short objectives can finish in twenty minutes, a standard 5x5 typically runs one to two hours, and marathon boards for events can run all day. You can also set a timer and score on squares held when it expires.
Can you play lockout bingo with any game?
Yes. The board holds objectives, not game rules, so anything you can verify can be an objective â video games, watch parties, sports broadcasts or real-life scavenger hunts. TCB ships curated objective decks for a range of games and lets you write your own card from scratch.
How do you stop people cheating at lockout bingo?
Most groups play on trust with proof by stream or screenshot. For competitive play, lock the card before the match so its objectives cannot be edited, run the board with a shared timer, and use the spectator view so everyone can see claims land in real time.
Is lockout bingo free to play?
On TCB, yes. Hosting and joining are free, no account is required, and there is no player cap charge or paid tier for the board features described on this page.
