Betting Rules
These Betting Rules describe how bets are placed, accepted and settled at M99 Casino on casino-m99online.com. They apply to pokies, crash games, fishing games, live dealer tables, table games and video poker, and they supplement our terms and conditions. By placing a bet you confirm that you have read and accepted these rules. If a rule here conflicts with a specific game's own rules, the game rules govern that game.
General Provisions
- Only players aged 18 or over with a verified account may place bets.
- All bets are placed in AUD and are final once confirmed.
- One person may hold one account and bet only for themselves.
- You are responsible for the actions taken through your account.
- We operate under a Curacao eGaming licence (8048/JAZ).
Acceptance of Bets
A bet is accepted when the game confirms it on screen and your balance is reduced by the stake. We may refuse or limit any bet at our discretion, for example where it exceeds a table maximum or breaches bonus rules. You cannot cancel or change a bet after it has been accepted, unless the game itself offers a feature such as a cash-out in a crash round.
Bet Types and Games
| Game type | How bets work |
|---|---|
| Pokies | Stake per spin, set by the paytable's available bet levels |
| Crash games (Aviator, JetX, Spaceman) | Stake before the round, with manual or automatic cash-out |
| Fishing and arcade games | Stake per shot or per round, as shown in the game |
| Live dealer | Bets during the betting window set by the dealer |
| Table games and video poker | Stake per hand or round with game-specific options |
Minimum and maximum stakes are shown in each game and may vary by provider.
Payouts and Settlement
Winnings are determined by the game's own outcome and are credited to your balance automatically after each round. The game's records, including those of the provider, are the final source for settlement. Crash round outcomes depend on the cash-out you make before the crash. If you disconnect during a round, the round is completed by the system according to the game rules, and you can check results in your history.
Void Bets
We may void a bet and return the stake in these cases:
- The game or round was interrupted by a technical fault.
- A bet was accepted in error or at an incorrect price.
- We find that the bet breached these rules or our terms.
- Fraud, collusion or the use of software to gain an unfair edge is suspected.
Winnings from a void bet are removed from the account.
Malfunctions
Malfunction voids all pays and plays. If a game, a server or a connection fails, we or the game provider will determine the outcome from the last recorded state. We are not responsible for losses caused by your own internet connection, device or battery. Tell our support team about any fault as soon as possible, and include the game name, time and round ID.
Bonuses and Betting
While a bonus is active, the maximum bet is A$5 per spin or round. Welcome bonuses carry 35x wagering to be completed within 7 days. Betting above the limit, using low-risk strategies such as covering opposite outcomes, or playing excluded games can lead to forfeiture of the bonus and related winnings. Full conditions appear in our bonus rules.
Responsible Betting
Bet only what you can afford to lose and set deposit and loss limits in your profile. You can pause or exclude your account at any time. Read our responsible gaming policy for tools and help organisations.
Disputes
If you disagree with the outcome of a bet, contact live chat or support@m99casino.com within 30 days, with your username, the game, the time and the round ID. We review game logs and the provider's records and give a written answer. Our decision is based on those records, and you can ask for a second review of our response.
Amendments
We may change these rules to reflect new games, regulations or technical changes. The current version is always available on this page, and continued play after a change means you accept it. See also the terms and conditions.
