With a GSB promo code you get extra value on top of what you deposit. Both newcomers and existing players can use one, either while signing up or just before paying in. Below we explain where to type it, how to confirm it is valid and which offers are running at the moment.
Where the GSB Promo Code Goes
On the sign-up form there is normally a box marked “promo code” or “voucher code”. Fill it in before you send your details, because once registration is finished you usually cannot go back and add it.
If you already have an account, log in to the account and you will see a similar box on the deposit page. That is the place for a gsb promotion code linked to a reload or seasonal deal, which has nothing to do with sign-up. Read the conditions of each code before you pay, as some offers only work if the code goes in before the payment, not after it.
After submitting, watch for a confirmation message or a line in your account summary saying the bonus has been added or is on its way.
GSB Promotions You Can Claim
Bookmakers tend to cycle through a handful of offers over the year. Typical examples are a gsb welcome bonus for your first deposit, which currently reaches up to ZMW 6,000 plus 100 free spins, free bets around particular sports events, and reload bonuses for players who come back.
Each promotion has its own conditions, so go through them before you opt in. Short-term campaigns often need a gsb promotion code, while permanent offers may kick in by themselves. If you want to see how these deals sit alongside everything else the site offers, see the full platform overview.
Some offers only accept certain payment methods or a minimum amount, so confirm you qualify first and save yourself a letdown.
Conditions Attached to the Welcome Bonus
You can normally claim the welcome bonus once per new account, and it is linked to your first deposit. To qualify you usually need to finish registering completely, including any identity checks the site asks for.
Most promotions also have wagering rules. These set how many times you must play through the bonus money (or what you win with it) before you are allowed to withdraw. The figures differ from offer to offer and can change, so the terms page is the only reliable place to check them.
Whether the welcome bonus is applied at all often comes down to entering the code properly during sign-up, so check it twice before you make your deposit.

Making the Deposit That Activates Your Code
In this market mobile money is the usual way to pay in, thanks to how widely it is used and how quickly it clears. You can normally use bank transfer or a card instead, though those may take longer.
After choosing how to pay, fill in the code box, if the offer needs one, before you confirm the payment. A gsb promotion code typed in once the money has already gone through usually will not activate the bonus, so get the order right.
Promotions often come with a minimum deposit, and if you pay in less than that, the bonus may stay locked even though the code itself was correct.

Activate and ClaimSeeing Your Bonus Balance
Once your deposit and code are processed, the bonus money should show up apart from your regular cash. Most accounts list it under something like “bonus balance”, kept separate from the funds you can withdraw.
Have a look at that balance shortly after paying in to be sure the gsb bonus arrived as it should. If it is missing, contacting customer service is the quickest way to get it sorted.
It also helps to keep an eye on your wagering progress next to the bonus balance. Both are shown together on the account page, which makes it easier to avoid problems later.
