How to Play
Buy cards, then watch. There are no decisions in bingo — everything after the purchase is the draw, and your cards mark themselves.
How to play
- 1Connect — sign in with Google to derive a Sui wallet instantly, or connect an existing Sui wallet.
- 2Buy cards — 1 SUI each, up to 20 in one purchase. The two-minute clock starts on the first purchase in the room, not when the room appears.
- 3Watch the draw — balls are called one at a time and your cards daub themselves. A completed line lights up gold.
- 4Check it — open History, pick a room, and press Verify to rebuild every card and the whole draw in your own browser.
The card
Five columns of five, headed B-I-N-G-O, and each column draws from its own range: B is 1–15, I is 16–30, N is 31–45, G is 46–60, O is 61–75. The centre square is free for everyone, so a card really holds 24 numbers, not 25.
That free centre is doing real work. The middle row, the middle column and both diagonals pass through it, so four of the twelve lines need only four called numbers instead of five.
What counts as a win
All three prizes pay in the same room — a line does not end the round. Typical balls are for a room of about a hundred cards; they arrive earlier in a busier room.
The line prize is deliberately the smallest, because it is the one that ties most often — 16% of rooms at a hundred cards, 34% at a thousand. Splitting a small prize is a footnote; splitting the main prize would feel like being cheated. Ties always split exactly, with the odd MIST going to the earliest purchase.
If too few people turn up
A room that closes with fewer than two players is void. Every card is refunded in full and no rake is taken — you are never charged 5% for a game that did not happen. Nothing goes into the progressive from a void room either.
How your cards are made
Your cards come from your own purchase transaction — its Sui digest plus your client seed — not from our seed. That matters: if cards came from the house seed, the house would be choosing which card each player got, which is worth rather more than knowing the draw.
The draw order is the other half, and it comes from a seed we commit to before the room opens, keyed over every purchase in the room. We fix our half while the room is empty and cannot predict the purchases that key it.
When the room settles, the seed is revealed immediately — no delay, because each room mints its own seed and never reuses it. Press Verify and your browser rebuilds every card from its buyer's transaction, rebuilds the draw from the revealed seed, re-scores every card, and re-prices every prize. Six separate checks, each reported on its own, so you can see which part of the claim holds rather than a single tick.
