About Bingosync

Bingosync lets people work on the same bingo board while racing a game. Create a room, share the link, and every square you mark shows up for everyone in the room in real time.

Left-click a square to mark it in your color. Right-click a square to star it privately, which lets you plan a route without other players seeing it.

Ways to play

Regular bingo
Complete the goals on the squares and mark them as you get them. Try to get five in a line: a row, a column, or a diagonal. Play in the same room as other racers to see each other's progress.
Multi-bingo
Like regular bingo with several lines at once. In "triple bingo" you might go for column 1, row 5 and the TL-BR diagonal to use their overlapping squares.
Anti-bingo
Your opponent chooses the line you have to complete. Combine with multi-bingo for triple-anti-bingo shenanigans.
Blackout
Instead of single lines, complete the entire board. Work together on one board in team blackout and compete against other teams.
Lockout
Only one player can own a square. Once it is collected the others are locked out. Collect as many as you can until the board is full or the timer runs out.
Flip lockout
Lockout where you can steal. Collect two squares adjacent to an opponent's square (no diagonals) to flip it to your color, even without the goal itself.

Adding a game

New generators and variants come from the community. A generator needs a goal list, a full name for the room dropdown, and a short name of roughly 10 to 12 characters for the room list.

There are two kinds of goal lists. An SRL-style list has 25 difficulty tiers (example): the generator takes one goal per tier and arranges them so every line adds up to a similar difficulty, and goals sharing a type never land in the same line. A simple list is just goal names (example) picked at random without synergy checks.

For a one-off board, use the Custom game type and paste a JSON list of 25 goals (example). The randomized custom variant shuffles a longer list for you.

Development and privacy

This site is a rebuild of bingosync by kbuzsaki, keeping its generators and board mechanics. Issues and pull requests for generators belong in the upstream repository.

Room names, player names, goal actions and chat messages are stored so old rooms stay reachable. A cookie remembers which rooms you have joined. No accounts, emails or other personal data are collected.
