What B337 is
Software you set up and control, in four parts.
Automated betting sessions
The B337 bot runs on your own computer. It logs in to bookmaker and exchange accounts you own, with the details you supply, and places bets by the strategy you attach: racing value bets, including ones that use the promotions and bonus bets already on your account, same game multis for the saver offers your account holds, or a tipster you copy. One session is one logged-in account. More on automated betting.
The Terminal
Live racing and sports odds from 40+ bookmakers beside Betfair back and lay prices, with price history and closing lines. A free account opens a limited view. More on odds comparison.
Tipster copy-betting
Tipster feeds with records tracked from tips placed through the platform. Copy one into your own bookmaker account and the stakes come from your own staking settings, never the tipster's. More on copy betting.
Betting API
A REST API that sends racing and sports bets into your own running sessions, for customers who want to drive B337 from their own code. More on the betting API.
Every placement, price and settlement lands in your dashboard, so you can check each bet against your bookmaker account. Bets settle automatically from the bookmaker's own settled-bet list and from official racing results.
Betting involves risk. Bookmakers can restrict or close accounts and void bets, automation can fail, prices move, and a positive expected value (+EV) bet can still lose. Promotions carry each bookmaker's own terms. There is no guarantee of profit. See responsible gambling for limits and support.
What B337 is not
- Not a bookmaker. B337 is software, not a bookmaker or wagering service provider. It does not take bets, set prices or accept wagers. Bets are placed in accounts you hold with Australian bookmakers.
- Never holds your betting money. Your money stays in your own bookmaker and exchange accounts, under their terms, and they settle your bets. B337 never holds it and never combines it with anyone else's.
- Not an agent. B337 does not act for any bookmaker. A session acts only on the strategy and limits you choose, in accounts you own, and you can stop it at any time.
- Not connected to the bookmakers. Bookmaker names are trade marks of their owners, and B337 is not affiliated with or endorsed by any of them. Many bookmakers restrict or prohibit automated betting in their terms.
- Not advice. Prices, expected values and tipster records are information, not advice, and we do not give personal financial or betting advice.
- Not a promise of profit. Nothing in B337 is a prediction, promise or guarantee of profit. Past results do not predict future results.
How B337 works
From signup to a running session, at a high level.
Create a free account
Sign up with your email address; you must be 18 or over. A free account opens a limited view of the Terminal with live odds.
Connect accounts you already hold
Add bookmaker and exchange accounts held in your own name. B337 works with 100+ Australian bookmakers, and it does not open accounts for you.
Choose a strategy and its limits
Attach a strategy to each session and set its rules: stake sizes with a minimum and a maximum, odds ranges and price floors, market and race filters, and the times it may run. Automated sessions need a paid plan.
Run the bot and check every bet
The bot runs on your own computer, and a session only bets while it is running. Each bet lands in your bet history with its price, and with its result once it settles.
The bot runs on Windows 10 or 11 (64-bit), on macOS 11 or later with Apple Silicon (not Intel Macs), and on Linux: Ubuntu 24.04 or later, or Debian 13 or later. The bookmakers page shows what works where, and how betting bots work goes into more detail.
How we count the platform figures
Our homepage shows two platform-wide totals. Here is exactly what each one counts.
Platform totals, all-time
- Bets placed
- 2.8M+
- Exact count: 2,807,744
- Total wagered
- $68.6M+
- Exact total: A$68,641,810
As at 28 Aug 2026. Source: B337's own bet records.
- Bets placed counts the bets recorded in B337 bet history across customer accounts, all-time. Sessions record each bet they place, and a customer can add a bet placed elsewhere to their own history; those count too.
- Settled and unsettled. A bet is settled once its result is in, from the bookmaker's own settled-bet list or from official racing results. The count also includes bets still waiting on a result, so it is not a count of settled bets only.
- Total wagered is the sum of the stakes on those same bets, in Australian dollars. A stake placed with a bonus bet counts at its face value.
- What is left out. Some bets are not counted, such as those in accounts their owners have hidden from profit and loss figures.
- Where it comes from. Both totals are calculated from B337's own bet records, the same records each customer sees in their bet history. The date beside them is when they were last read from those records.
These are volume figures, not results. They do not show whether those bets won or lost, and they say nothing about what you would win or lose. Past results are no guarantee of future results.
How we think about responsible use
Betting can be harmful, and automation makes it possible to bet far more, far faster, than by hand. So a session only bets inside the limits you set, and you can stop it whenever you choose.
- 18+ only. You must be 18 or over to hold a B337 account, and signup asks for your date of birth.
- Limits you set. Minimum and maximum stakes, odds ranges and the times each session may run. Racing sessions can also stop themselves at a profit or loss figure you choose.
- Stop at any time. You start and stop every session yourself, and sessions only run while the bot is running on your computer.
- Your bookmaker's tools still apply. Use the deposit and loss limits your bookmaker offers, and only stake what you can afford to lose.
- Self-exclusion. BetStop (betstop.gov.au), the National Self-Exclusion Register, is a free Australian Government service that lets you block yourself from Australian online and phone betting providers.
- Closing your account. Ask us to close your B337 account at any time and we will. Email support@b337.bet.
For free and confidential support call 1800 858 858 or visit gamblinghelponline.org.au.
The responsible gambling page has more on limits, self-exclusion and getting help.
Your data and security
To log in to your bookmaker accounts, the bot needs the login details you give it. They are held only so the bot can act on your settings, and they are never shown to other users. Data is encrypted in transit, you can turn on two-factor authentication for your B337 account, and we never sell your data.
The security page explains how logins and account data are handled, and the Privacy Policy sets out what we collect, why, and how to access, correct or delete it.
