How to play
Pick a room. Before the round starts, open the card selection, browse the round's numbered cards (free) and tap the ones you want — up to the room's limit (2 per player). Tap Confirm Cards & Join Round: the entry fee is taken per card from your Real Balance (Deposit first, then Withdrawable). Bonus Balance can never be used.
Every card is made by the server for that round, as a traditional Bingo card: each column has 5 different numbers from its own range — B 1–15, I 16–30, N 31–45, G 46–60, O 61–75 — chosen at random (no free space). A card can belong to only one player. Once you confirm, your cards are locked for the round — nobody, not you and not us, can change them.
The round starts when the room has its minimum number of players, after a short countdown. Card selection closes when the first number is drawn.
The server calls numbers from 1–75 without repeats, one about every second, in the same order for every player. When a called number is on your card, that number flashes five times — it is not marked for you. Tap a called number to mark it (tap again to unmark). Numbers that have not been called yet can't be marked. A called ball's letter (B 1–15, I 16–30, N 31–45, G 46–60, O 61–75) tells you which column to look in.
Winning — press BINGO!
A winning pattern is any row, any column or either diagonal (12 possible lines) on one of your cards, with all 5 numbers called and marked by you.
Nothing is claimed for you: when a card has a winning pattern, press the BINGO! button of that card (every card has its own). The server checks that card against the numbers it has called and your marks. A wrong claim pays nothing and blocks that card's BINGO! button for the rest of the round — your other cards keep playing and can still claim.
Marking a number marks it on all your cards at once (tap again to unmark it everywhere).
The first valid BINGO stops the calling. Everyone else then has 3 seconds to claim BINGO on the same numbers; every valid claim in that time is a winner and the prize pool is split equally (one share per player, however many lines or cards).
If nobody makes a valid claim by the end — all 50 numbers called plus 8 seconds of last call — there is no winner and every entry is refunded in full, even if a card had an unclaimed line.
Prize pool
Prize pool = 90% of all entries collected in the round (rounded down to the cent). The remaining 10% is the operator's share. Nothing else is deducted.
With several winners each gets the pool divided by the number of winners, rounded down to the cent; the leftover cents (if any) go one each to the winners in a fixed order (by account id), so exactly the whole pool is paid.
Prizes are paid to your Withdrawable balance the moment the round is settled. Refunds go back to the balance the entry came from.
A round that cannot go ahead (not enough players within the room's waiting time, room closed before it started, or a server problem) is cancelled and every entry is refunded.
Fair draws
Winners are never chosen: the same draws and the same published rules apply to every card, and the result depends only on the cards, the called numbers and the valid BINGO claims — never on who you are, your balance or your past wins and losses. Before anyone joins, the round shows the SHA-256 fingerprint of a secret server seed made with a cryptographic random generator. The draw order and every card in the round's selection are calculated from that seed (HMAC-SHA256), and the seed is revealed when the round ends. Open any finished round (Recent rounds or My games) and tap Check this round: your browser recomputes the fingerprint, the draw order, the cards and checks every winning claim by itself.
