Matchbook is offering new customers a 20% rebate on their overall net exchange losses when they sign up using the bonus code REBATE20. Rather than a standard “bet and get” free bet, this offer works retrospectively: if you end up down overall after betting on the exchange, Matchbook pays back a fifth of that net loss as free bet tokens.
It's a different structure to the fixed-stake sign-up offers you'll see at conventional bookmakers, and it suits customers who plan to bet regularly on the exchange rather than place a single qualifying bet.
Because this is a rebate rather than an instant sign-up bonus, the free bet tokens are only generated after your net losses have been worked out, so they won't appear in your account the moment you register. Once credited, free bet tokens typically sit in a separate balance from your main cash balance and can be selected specifically when placing a bet on the exchange.
When you use a free bet token, you're generally staking the token itself rather than your own cash, so any returns are usually paid out as winnings only, with the stake not returned. The exact expiry window and any market restrictions on where free bet tokens can be used aren't stated in the significant terms provided, so it's sensible to check your account dashboard or the full terms and conditions once the token is credited, so you know the deadline for using it.
The bonus code REBATE20 needs to be entered during the sign-up process. This offer is specifically for new users, so existing Matchbook customers won't be able to claim it by entering the code retrospectively.
The significant terms describe the rebate as 20% of overall net exchange losses for new users, but they don't state a specific minimum deposit, minimum odds, or minimum stake for bets to count. Rather than guessing at figures, check your Matchbook account or the offer's full terms once you've registered, since operators often list these details separately from the headline promotion.
The rebate is based on your net exchange losses, meaning Matchbook will look at your overall win/loss position across your qualifying bets rather than refunding you after every single losing bet. If your net position is a loss, 20% of that net figure comes back as free bet tokens; if you're in profit overall, there's no loss to rebate.
No payment method exclusions are listed in the significant terms supplied, and no expiry period for the free bet tokens is specified either. As these details aren't confirmed here, treat them as unconfirmed until you've checked your account, and don't assume every deposit method or an indefinite claim window will apply.
Because the reward is paid as free bet tokens rather than cash, any winnings generated from using those tokens are typically credited as withdrawable funds once the bet settles, though the stake itself (being the token, not your own money) usually isn't returned alongside the winnings.
Matchbook is a licensed betting exchange rather than a traditional fixed-odds bookmaker, which changes the way you interact with markets. Instead of accepting a price set by the bookmaker, you can back or lay outcomes against other customers, effectively setting or matching your own odds. Matchbook takes commission on net winnings rather than building a margin into every price, which is the trade-off for the extra control you get over your own odds.
This structure tends to appeal most to customers who already understand exchange betting — knowing the difference between backing and laying, and being comfortable that liquidity (the amount matched at a given price) can affect whether your bet gets taken at all. If you're used to a conventional bookmaker app where you simply tap an outcome and confirm a stake, the exchange model takes a bit of getting used to, even though the underlying concept is simple once you've placed a few bets.
No specific standout features such as cash out, bet builder tools, or live streaming have been listed for Matchbook in the information available, so it's worth exploring the site directly to see what's currently offered on top of the core exchange functionality.
Once you've claimed the REBATE20 welcome offer, Matchbook runs a number of ongoing promotions aimed at regular customers, mostly built around the same rebate concept applied to different bet types. These have included:
Because Matchbook leans heavily on the rebate format across its promotions, it's worth getting comfortable with how net losses are calculated early on, since the same principle applies across most of its ongoing offers. Always check the specific terms of each promotion before opting in, as caps, qualifying markets and rebate percentages vary between them.
As an exchange rather than a standard bookmaker, Matchbook's mobile experience is built around presenting back and lay prices clearly enough that customers can place bets on the move without needing a desktop screen full of market depth. General exchange apps of this type tend to prioritise speed and clarity of pricing over flashy extras, and Matchbook's app should be judged on how well it lets you match bets, track your open positions, and manage free bet tokens like the ones from this offer. No specific app rating or feature list has been confirmed here, so it's worth trying the app yourself once you've registered to see whether the exchange format works for how you like to bet on mobile.
The REBATE20 offer is genuinely different from most welcome bonuses in that it protects you retrospectively rather than rewarding a single qualifying bet. If you're planning to bet regularly on the exchange and understand that some sessions will end in a net loss, a 20% rebate on that net loss softens the downside in a way that a one-off free bet doesn't.
The trade-off is that it requires you to already be comfortable with exchange betting to get full value from it — if you're new to backing and laying, the learning curve may matter more than the size of the rebate. Since key figures like minimum deposit, qualifying odds and expiry aren't set out in the headline terms, it's worth reading the full terms in your account before assuming the offer works exactly like a typical sign-up bonus.
We haven't scored this offer. Matchbook's terms don't state the qualifying spend or reward value, and we'd rather show you their exact wording than a number we couldn't stand behind.
We can't give a considered verdict on this one yet. Matchbook's terms don't state enough for us to work out what it costs you or what it pays, and we'd rather say that than guess. Their full wording is below — read it before you commit anything.
