How to play 990x

Press Place bet. One number from 1 to 1000 is drawn the moment you bet.
If the number drawn is yours, you win. A bet worth $0.20 or less (1M OSRS gold) pays 990x; a bigger bet pays 950x.
In Auto, set how many bets to place (0 keeps going until you stop it) and, if you like, a profit or loss to stop at. Autobet always stops when your number hits.
About 990x
Every number from 1 to 1000 is equally likely on every bet, and the draw never remembers the last one, so no number is ever due. Picking the same number every time is exactly as good as changing it.
The most you can bet on 990x is 5M OSRS gold, or the same value in RS3 gold or Fire Tokens.
990x FAQ
What is the house edge on 990x?
1% on bets worth $0.20 or less, which pay 990x on a 1 in 1000 chance, and 5% on bigger bets, which pay 950x.
Why do bigger bets pay 950x?
That is the rule of the game: 990x is for small bets, and anything over the line pays 950x. The bet box shows which one your bet is on before you place it.
Is 990x provably fair?
Every round is generated from a server seed that is hashed and shown to you before you bet, combined with a client seed you control and an incrementing nonce. When you rotate your seed the old server seed is revealed, so you can replay every round it produced and confirm nothing changed after the fact.
