King Billy Casino – 100% up to €/$500 + 100 Free Spins, First Deposit Bonus
King Billy Casino's first deposit bonus is a 100% match up to €/$500 plus 100 free spins, from a €/$20 minimum deposit, with 30× wagering, a €/$5 maximum bet and a maximum win of 3× the deposit. It is the first of four welcome deposits that sum to 300% and €/$3,000 plus 450 spins on paper. The standout detail is the gate around the offer: crypto deposits do not qualify, and the spins arrive in two packs. This bonus has not been tested by our staff.

IMPORTANT
The package reads €/$3,000 + 450 spins, but reaching all four caps takes about €/$4,167 of deposits: an effective 72%. Turnover at the caps is €/$90,000 if 30× applies to the bonus and €/$215,000 if it applies to deposit plus bonus. The minimum deposits total €/$80 against that €/$4,167, and a crypto deposit does not qualify at all.
A ladder whose cost sits in the gates, not the headline
The match percentages are ordinary. What shapes the value is the surrounding gating: the deposit rail, the 7-day clock, the €/$5 maximum bet and a maximum win tied to the deposit.
MAKES SENSE IF
- The deposit is made with a non-crypto method.
- A modest first deposit can be played inside the 7-day window.
- The package is judged at its effective 72%, not at the 300% sum.
LESS GOOD IF
- The deposit would be made in crypto, which does not qualify.
- The full €/$500 bonus is the target: €/$15,000 to €/$30,000 of turnover in 7 days.
- Winnings beyond 3× the deposit are expected.
Following the first deposit through its gates
The first leg needs a non-crypto deposit of at least €/$20 and no code. At the minimum the bonus is €/$20 and the balance €/$40. Because the wagering basis is not marked, 30× reads two ways: on the bonus alone, €/$600 of turnover and about €/$24 of expected loss at 96% RTP; on deposit plus bonus, €/$1,200 and about €/$48 (illustration). At the €/$500 cap the balance is €/$1,000: €/$15,000 or €/$30,000 of turnover, with expected loss of €/$600 or €/$1,200, against an average exhaustion point of €/$25,000 (balance divided by 4%). At the €/$5 maximum bet that is at least 3,000 or 6,000 bets inside 7 days, or about 430 to 860 a day. The maximum win of 3× the deposit is €/$60 at the minimum and €/$1,500 at the cap. Match structures are compared on the first deposit match page.
The first deposit is one of four legs: 50% up to €/$500 with 150 spins (WELCOME2), 75% up to €/$1,000 with 100 spins (WELCOME3) and 75% up to €/$1,000 with 100 spins (WELCOME4), all from a €/$20 minimum with 30× and a €/$5 maximum bet. The gates differ by leg: the second spin pack follows after 10 minutes on deposits 2 and 3, but after 24 hours and a 1× wagering requirement on deposits 1 and 4, and deposit 4 lifts the maximum win to 5× the deposit. Reaching every cap takes about €/$4,167 in deposits (€/$500, €/$1,000, €/$1,333 and €/$1,333) for €/$3,000 of bonus: an effective 72%, against the 300% sum. Turnover at the caps is €/$90,000 on the bonus basis and €/$215,000 on the deposit-plus-bonus basis, with expected loss of about €/$3,600 or €/$8,600. The 450 spins are counted in the headline and not priced. Whether the legs can run at the same time is not stated.
Four points need a check before depositing: the wagering basis; what “deposit sum” means for the maximum win and whether the spin result counts inside it; what the 1× requirement on the first spin pack is measured on; and which deposit methods are treated as crypto. The spins are covered in a separate article and catalogued on the free spins with deposit page. This offer has not been tested by our staff, so the credit of the match and the spin packs remains unobserved.

King Billy first deposit bonus: common questions
How is the 30× wagering calculated?
The terms list 30× without marking the basis. On the bonus alone, a €/$20 deposit gives €/$600 of turnover and about €/$24 of expected loss at 96% RTP; on deposit plus bonus, €/$1,200 and about €/$48 (illustration). At the €/$500 cap the figures are €/$15,000 and €/$30,000. The cashier is the binding source.
What is the whole welcome package worth?
Four deposit bonuses sum to 300% and €/$3,000, plus 450 free spins. At the caps, about €/$4,167 of deposits earns €/$3,000 of bonus: an effective 72%. Turnover is €/$90,000 on the bonus basis or €/$215,000 on the deposit-plus-bonus basis.
Does a crypto deposit qualify?
No. The welcome package terms state that the bonuses are unavailable for crypto deposits. Use a non-crypto method for the qualifying deposit, and confirm in the cashier how each method is classified.
How is the bonus activated?
The first deposit bonus needs no bonus code. Later legs use the codes WELCOME2, WELCOME3 and WELCOME4. The minimum deposit is €/$20, with local-currency equivalents listed in the terms (A$30, C$30, NZ$30, 200kr, R400).
What is the maximum win?
3× the deposit sum, as stated, so €/$60 on a €/$20 deposit and €/$1,500 on €/$500; the fourth deposit allows 5×. The free spins carry a separate €/$100 cap. Whether the spin result counts inside the 3× is not stated.
What are the time limits and the maximum bet?
Percentage bonuses must be wagered within 7 days of activation. Free spins must be used within 24 hours and wagered within 7 days. The maximum bet is €/$5 (A$7.5, C$7.5, NZ$7.5, 50kr or R100 in other currencies). At the €/$500 cap that is at least 3,000 or 6,000 bets, depending on the basis.
How do the free spins fit in?
The first deposit bonus carries 100 spins on Train Heist Johnny Cash (BGaming) in two packs of 50: the first is credited immediately and the second after 24 hours if 1× wagering on the first pack has been met. The maximum win on the spins is €/$100. They are covered in a separate article.
Who can claim this bonus?
The welcome package applies to the first four deposits, in order, and the first deposit bonus to the first deposit. The welcome terms list no country restrictions, but eligibility can vary by country and by payment method, so verify availability for your region in the cashier or with support before depositing.
How we verified this bonus
This bonus has not been tested by our staff. Verify terms before depositing, in particular: the wagering basis (bonus alone or deposit plus bonus), what “deposit sum” means for the maximum win and whether the spin result counts inside it, what the 1× requirement on the first spin pack is measured on, which deposit methods are treated as crypto, game contribution for the titles you plan to play, whether the legs can run at the same time, and the eligible player group.
The short version
Treat it as a 72% ladder dressed as 300%: worth claiming with a modest non-crypto first deposit, and only once the cashier confirms the wagering basis and the maximum win.
