The Games

Price Prediction

Say whether a price will be higher or lower five minutes from now. A new round starts every five minutes, all day, and every one of them is decided by two numbers the whole world can check.

This is the simpler of the two games and the faster one. A round runs on a fixed clock, you pick a side, and ten minutes later you know. There is nothing to research and nothing to read — which is exactly why it is worth understanding what you are actually up against before you start.

How a round runs

Rounds overlap. While one round is being decided, the next one is already taking bets, which is why the rail always has a card you can act on.

One round, two five-minute halves. You can only enter during the first. The lock price is stamped at the halfway point and the close price five minutes later — the entire deciding window is one you cannot act inside.

1
The round opens
It appears on the rail with two buttons, UP and DOWN, and a countdown to its lock. Both sides start at roughly 2.00× because the house seeds them evenly.
2
You pick a side
One entry per wallet per round — the contract refuses a second one with Can only enter once per round. Choose the amount and confirm.
3
The round locks
Entries stop and the lock price is recorded on chain. This is the number your bet is measured from. Nothing can be entered, changed or withdrawn from here on.
4
Five minutes pass
The price does whatever it does. The card stays on the rail showing the live price against your lock price, so you can watch it, but there is nothing left to do.
5
The round closes
The close price is recorded. Higher than the lock price and UP wins; lower and DOWN wins. The card turns into a result.
6
You claim
Winnings are not pushed to you — you collect them with a transaction, whenever you like. There is no deadline.

Exactly equal is nobody's win

If the close price lands on precisely the lock price, the round is a tie and every stake becomes refundable — winners and losers alike get their money back and the house takes nothing. It is rare, but it is the honest answer to a question with no answer.

What decides the price

Each trading pair names its own source, and the card tells you which one it is using. Two kinds exist:

An off-chain feed — the price is read from an exchange and published to the contract by the operator at the lock and at the close, alongside a proof of the reading.
An on-chain oracle — the contract reads a price feed directly, with no operator in the path at all.

Both prices for a round end up stored on chain permanently. You do not have to take anyone's word for what the lock or close price was; you can read them out of the contract long after the round is gone from the screen.

How the payout is worked out

Both pools are added together, the house takes its cut, and what is left is divided among the winners in proportion to what each of them staked.

A round where 3 BNB backed UP and 1 BNB backed DOWN. UP wins, so the whole 4 BNB pot — less the 5% house cut — is shared out across the 3 BNB that backed it.

Notice what that means: the side with less money on it pays more. Backing the crowd is safe and cheap; backing against it is where the multipliers are. The house does not choose those numbers and cannot move them — they are a consequence of where everyone else put their money.

Your own bet moves your own price

A large stake on a thin side dilutes itself. Put 1 BNB on a side holding 0.2 BNB and you now own most of that pool — the multiplier you saw before you pressed the button was computed without your money in it. Check the quoted return on the confirmation screen, not the number on the card.

When a round pays nobody

Three situations end a round without a winner, and all three refund every stake in full:

A tie: The close price equals the lock price exactly.
A cancelled round: The operator voided it — usually because a price could not be published inside the window the contract allows.
A round that never closed: Nothing was recorded for it. After a short delay the contract lets you refund yourself without anybody's permission.

In all three the house cut is zero. A refund returns exactly what you put in.

The limits

Minimum entry: 0.001 BNB
Maximum entry: 10 BNB per bet
Entries per round: One per wallet. Pick a side and an amount once.
Round length: Five minutes of betting, then five minutes blind.
House cut: 5% of the pot, and only on rounds that pay out.

What the contract guarantees you

Entries after the lock are impossible. The lock and close prices are permanent and public. Unclaimed winnings never expire. And a round that goes unresolved becomes refundable by you, without needing the operator to act.
