Zombillion Bonus
New players at Zombillion Casino unlock a 100% match on their first deposit plus a stack of free spins, and Zombillion keeps the offers coming after that. Three welcome deposits, a handful of reload promotions, and a cashback ladder make up the full Zombillion casino bonus lineup, and a few of these need a code to activate.

Zombillion Welcome Bonus Explained
Sign up at Zombillion Casino and use your first three deposits to unlock three matches worth up to £550 combined, plus 150 free spins across the set. Each stage runs on its own 7-day clock, so clear the wagering before the timer runs out.
Deposit One: 100% Match
Deposit £10 or more and Zombillion doubles it, up to £200, and adds 100 free spins on a featured slot. Enter the code ZOMBIE100 before you deposit, then clear the 35x wagering requirement within 7 days to withdraw the winnings.
Deposit Two: 50% Match
Deposit again and Zombillion matches 50% up to £150, plus 50 free spins, when you use the code GRAVE50. The minimum deposit stays at £10, the wagering sits at 35x, and you get 7 days to clear it.
Deposit Three: 75% Match
Your third deposit gets no free spins, but Zombillion pushes the match to 75%, capped at £200. Use the code CRYPT75, deposit at least £10, and clear the 35x wagering within a week.
Zombillion Bonus Codes Worth Knowing
Not every Zombillion casino bonus code applies to new accounts. Some unlock reload offers for existing players, and one targets high-stakes depositors.
Use the code UNDEAD25 for the Sunday reload: deposit £20 or more on a Sunday and Zombillion adds 25%, up to £75. You can claim this once a week, and Zombillion marks the day using UTC time.
Use the code BRAINS50 for the high-stakes bonus: deposit £250 or more and Zombillion matches 50%, up to £400. The offer lasts 3 days, and you can claim it once every 7 days.
Cashback and Free Spins
Weekly Cashback Ladder
Zombillion pays cashback on losses every week, and the percentage climbs with how much you deposit across that week:
- 5% on deposits between £20 and £500
- 7% on deposits between £501 and £1,000
- 9% on deposits between £1,001 and £2,500
- 12% on deposits between £2,501 and £5,000
- 15% on deposits above £5,000
- 25% for VIP-tier players, by invitation only
No code applies here. Zombillion calculates the cashback each Monday and adds it to your balance.
Free Spins Pool
Zombillion drops 5,000 free spins into a shared pool every Friday and splits them between active players based on how much each person wagered that week. No code, no minimum deposit. Play through the week and check your account for spins on Friday morning.
Slot Tournament and Prize Pool
Zombillion runs a weekly slot tournament and splits a £5,000 prize pool across the top 50 spots on the leaderboard. Points accrue from real-money spins on the featured game list, and Zombillion resets the leaderboard every Monday at midnight UTC.
How to Claim a Zombillion Casino Bonus Code
- Log into your Zombillion account or register a new one.
- Head to the cashier and pick a deposit method: Visa or Mastercard debit, PayPal, Pay by Phone, or Open Banking.
- Enter the bonus code in the promo field before you confirm the deposit.
- Deposit the minimum amount the offer requires.
- Check your account balance for the matched bonus and any free spins.
Wagering Requirement in Numbers
Claim the £200 first-deposit match and the 35x requirement applies only to that £200, not your deposit. That works out to £7,000 in real-money wagers before you touch the winnings. Slots count in full toward that target; live dealer tables count for less, so grinding blackjack won't clear it as fast as spinning slots will.
Wagering Requirements and Withdrawal Rules
Every deposit bonus at Zombillion carries a 35x wagering requirement, and Zombillion calculates it on the bonus amount rather than the deposit. A £200 bonus means you wager £7,000 before you withdraw any winnings tied to it. Slots contribute 100% toward the requirement, while live dealer games and table games contribute less, so check the terms on each offer before you commit your bankroll to one game type.
Zombillion pays withdrawals back through the method you used to deposit where possible. Debit card and PayPal withdrawals take up to 5 business days, and Open Banking transfers land within 24 hours.

| 4. If the validity window closes before you clear the wagering, Zombillion removes the bonus and any winnings tied to it from your balance. |
| 5. Zombillion credits most bonuses to your account within minutes. Contact support if yours doesn't show up. |

What is the Zombillion bonus code for new players?
ZOMBIE100 unlocks the first-deposit match. Enter it before you deposit £10 or more, and Zombillion doubles your money up to £200 plus 100 free spins.
How many Zombillion bonus codes can I use at once?
One at a time. Zombillion allows a single active bonus per account, so pick the offer you want before you deposit rather than stacking codes.
Do I need a Zombillion casino bonus code for the cashback offers?
No. The weekly cashback and the Friday free spins pool land in your account without a code. Codes apply to the welcome deposits, the Sunday reload, and the high-stakes match.
What's the wagering requirement on a Zombillion bonus?
35x on the bonus amount, not the deposit. A £150 bonus needs £5,250 in wagers before you can withdraw the winnings, and you've got 7 days to get there on most offers.
Can I withdraw a Zombillion casino bonus without wagering it first?
No. Zombillion holds the bonus and any winnings tied to it until you clear the wagering requirement inside the validity window. Miss the deadline and both disappear from your balance.
