1st Deposit Welcome Offer

1st Deposit Welcome Offer: the full guide

1st Deposit Welcome Offer is Costabingo’s offer of up to £100 for a £10 deposit with 10× wagering. Everything below is taken from Costabingo’s own promotion page, with the operator’s wording kept beside each figure, and the arithmetic marked as arithmetic.

What 1st Deposit Welcome Offer actually is

A welcome offer is the one promotion an operator will never quietly weaken, because it is how the account is won in the first place. It is also the offer with the most conditions attached, and the conditions are where two apparently identical “100% up to £100” deals stop being identical.

Read it in this order: what you must pay in, what you get back, what you must do with it, and what happens to the winnings. Three of those four are usually in the headline. The fourth — what happens to the winnings — is where the money actually is.

Costabingo publishes this one as “1st Deposit Welcome Offer”. It asks for £10 to qualify. It is open to new accounts only, so an existing customer reading this should treat it as background rather than as an option.

How to claim it, step by step

1. To claim this offer, you must click the 'Deposit' button under the 'Offers' tab, and make your deposit as set out in these significant terms.
2. The minimum deposit to claim is £10 with code: GAME50

Steps are taken from the operator’s own instructions where it publishes them, and otherwise assembled from the conditions it does publish. The quote under a step is the sentence it came from.

The conditions that decide whether it is worth taking

What it works out to

• £100 × 10 = £1000 to stake before withdrawalEvery spin or bet counts towards that total, win or lose — it is turnover, not losses.
• £10 in, up to £100 back = 10× your depositUseful for comparing offers that look different but ask for the same money.

This arithmetic is ours, not the operator’s: Costabingo publishes the figures it is built from, not the totals. Check the sums — they are deliberately simple enough to check.

What 10× wagering means in pounds

Wagering — playthrough, turnover, rollover: the words change, the arithmetic does not — is the number of times the reward has to be staked before the balance can be withdrawn. Here Costabingo sets it at 10×.

On £100 of bonus that is £1000 of stakes. Not £1000 of losses: every bet counts towards the total whether it wins or loses, so a run of small wins moves you through the requirement without costing anything. A run of losses ends it early for the obvious reason.

Two details decide how painful 10× really is. The first is which games count: slots usually count in full, table games often count at a fraction or not at all, and a stake that does not count is a stake wasted. The second is the maximum bet allowed while wagering — exceed it once and operators are entitled to void the bonus and everything won with it.

Compared with the rest of the market, this is at the low end, and unusually kind.

Who this suits, and who should leave it

It suits players on a small budget, since the entry price is low.

It is the wrong offer for existing customers, who are not eligible.

In its favour: wagering 10× — low for the market; £10 minimum deposit; reward worth £100; 10.0× your deposit back in play.

Against it: only 5 days to use it; winnings capped at £100; promo code needed: game50; opt-in required; new customers only.

None of that is a recommendation to play. It is a summary of conditions the operator has published, arranged so the trade-off is visible in one place.

How people lose this kind of bonus

Four things account for most lost bonuses, and none of them is bad luck.

Not opting in. This offer requires opting in before you play. Deposit first, opt in later, and the deposit does not count — operators almost never apply a promotion retrospectively.

Paying in from someone else’s account. UK operators require the payment method to be in the account holder’s name; a shared card voids both the bonus and the withdrawal.

Missing the window. Rewards expire, and the clock usually starts when the reward is credited rather than when you first log in after that.

Betting above the maximum allowed while wagering. One oversized stake is enough for an operator to void a bonus and the winnings attached to it, and this term is enforced far more often than people expect.

Before you claim it

Verify the account first. Every operator licensed in Britain has to confirm identity and age, and it is far easier to do it before there is a withdrawal waiting than after. An unverified account can claim a bonus and then be unable to take anything out of it.

Set the limits while you are still calm. Costabingo, like every UK licensee, has to offer deposit limits, session reminders and a self-exclusion option; they take a minute to set and cannot be quietly removed the moment a losing session starts — a cooling-off period applies to loosening them.

Then read the terms below once, slowly. If a condition in them makes the offer not worth taking, that is the offer telling you something useful, and it costs nothing to walk away at this point.

If the bonus does not arrive, or is taken away

Start with Costabingo’s own support and put the complaint in writing, quoting the condition you believe you met. Operators have to have a complaints procedure and have to tell you how long it will take.

If the answer does not settle it, the operator must offer an independent adjudicator — an ADR body approved by the Gambling Commission. That service is free to the player, and the operator is bound by its decision in a way you are not.

The Gambling Commission itself does not settle individual disputes, but it does act on patterns: if an operator is misleading people about promotions, the Commission is where that record is built. And if the problem is the playing rather than the bonus, GamStop blocks every British-licensed site at once, while GamCare and BeGambleAware offer free, confidential help.

How this page was put together

Every figure above was copied from Costabingo’s own promotion page — not from a press release, an affiliate feed or another comparison site — and the operator’s wording is kept beside the value so it can be checked. The page was last read on 26 September 2026.

Where the operator states nothing, this page says so instead of filling the gap. Where a number is ours rather than theirs — the arithmetic in the worked example — it is labelled as ours.

The rating is worked out from those same conditions by a published formula, identical for every operator on this site, paying or not: the method is here. Nothing about this page is negotiable by the operator, which is the only reason it is worth reading.

Questions people ask about this offer

Do I need a promo code for the Costabingo offer?

Yes. Costabingo publishes the code GAME50, to be entered deposit. Without it the offer does not apply.

How much do I have to pay in?

The page states a minimum deposit of £10. Paying in less does not trigger the offer, and paying in more does not increase it unless the terms say so.

Can I withdraw the winnings straight away?

Not immediately. The reward carries a 10× wagering requirement, which means staking it 10 times over before the balance becomes withdrawable.

When does it end?

The page gives no end date. It runs until the operator withdraws it, and this site records the day that happens.

Is this offer available to existing customers?

No. The terms limit it to new accounts or a first deposit. Existing customers should look at the operator’s reload and weekly offers instead.
