Sign up at Big Win Box and you get a Big Win Box bonus on each of your first three deposits, worth up to £450 plus 250 free spins in total. After that come a Sunday reload, weekend roulette prizes, weekly cashback and tournaments with prize pools from £2,500 to £75,000. Pick the offers that fit your budget and the games you play.
The UKGC banned credit cards for gambling in 2020, so fund your deposits with a Visa or Mastercard debit card, PayPal or an Open Banking transfer, wherever the cashier lists them. The welcome offers need £15, Sunday reload needs £30 and the high roller bonus needs £300.
Big Win Box Casino Bonus Types
Big Win Box splits its casino bonus offers by player type. New accounts get the welcome package, regulars collect cashback, rakeback and reloads, and anyone can enter the tournaments.
Welcome Package for New UK Players
The welcome package spreads across your first three deposits. Each instalment is separate, so you claim them one at a time.
First Deposit
Your first deposit gets a 100% match up to £150 plus 150 free spins. A £15 deposit qualifies. Put in £150 and you play with £300. The bonus lasts 7 days and carries a 35x wagering requirement, so a £100 bonus means £3,500 in bets before you can withdraw.
Second Deposit
The second instalment pays 55% of your deposit up to £150 and adds 100 free spins. A £100 deposit brings £55 in bonus funds. The minimum is £15 again, the bonus lasts 7 days and the wagering requirement stays at 35x.
Third Deposit
Your third deposit repeats the first offer without the free spins: a 100% match up to £150, valid for 7 days. The cashier shows the wagering multiplier before you confirm the deposit.
Cashback and Rakeback
Live-O-Mania
Live dealer games take more focus than slots, and Big Win Box pays cashback on live game losses each week, up to 25%. Lose a session of live blackjack or roulette on Tuesday and you get a share of it back.
Weekly Cashback
Weekly cashback covers every game in the lobby. The more you deposit in a week, the higher your percentage. A week with £1,200 in deposits lands in the 8% band.
| Weekly deposits | Cashback |
|---|---|
| £20 to £500 | 5% |
| £501 to £1,000 | 6% |
| £1,001 to £2,500 | 8% |
| £2,501 to £5,000 | 10% |
| Over £5,000 | 12.5% |
| VIP invitation | 25% |
The 25% tier is invite-only. Big Win Box offers it to VIP players, and you climb the loyalty ranks by playing more.
Rakeback
Reach silver in the loyalty ranks and you get weekly rakeback of up to 17%. This offer needs no Big Win Box casino bonus code. The percentage climbs again when you reach gold and platinum.
Roulette Weekends and Free Spins
Roulette Weekends
Every weekend, Big Win Box attaches extra prizes to specific roulette bets, and the riskier bets carry the bigger extras. The format changes from week to week. If you play slots most of the time, give the wheel a session or two anyway.
Clucking Spins
Big Win Box gives away 10,000 free spins each week through Clucking Spins. Every player can enter and the pool resets weekly, so a quiet week costs you nothing but the chance.
Big Win Box Bonus Codes
Two Big Win Box bonus codes are live right now: 50HIGH for the high roller bonus and RELDAY for the Sunday reload. Every other offer on this page needs no code. You enter a Big Win Box bonus code in the cashier when you make the deposit, so check it before you confirm.
Highroller Bonus: 50HIGH
Deposit at least £300 with the Big Win Box casino bonus code 50HIGH and you get 50% back as a bonus, up to £500. A £300 deposit brings £150. The bonus lasts 3 days and you can claim it once every 7 days, so space your big deposits.
Sunday Reload: RELDAY
Deposit at least £30 on a Sunday with the code RELDAY and you get 25% of the amount, up to £100. A £400 deposit reaches the cap. You can claim it once each Sunday, and Big Win Box counts the day by UTC, so a late deposit on a UK Sunday evening in summer still counts, but one after midnight local time does not always.
Tournaments and the Fortune Wheel
Daily Bronze and Rookie Rumble run every day with a £2,500 prize pool each, which makes £5,000 across both. The more you play, the better your position on the leaderboard. Jackpot Jewel carries the biggest prize at £75,000 and every player can join.
The live tournament covers live dealer games only and resets every three days with a £10,000 pool. The Fortune Wheel hands out free spins, cash bonuses and smaller extras, so a spin always has something on it.
How to Claim a Big Win Box Bonus
Register an account, make a deposit that meets the minimum and the bonus appears in your balance. Enter the code at the cashier for the two code offers. If a bonus fails to show up after your deposit, contact support straight away and quote the offer name.
Big Win Box Bonus Terms and Conditions
Big Win Box limits you to one offer at a time unless the promotion says otherwise. It suspends accounts it catches gaming the bonus system and reports fraud to the regulator. Bonuses with wagering requirements need you to hit the multiplier inside the validity window. Miss the deadline and Big Win Box removes both the bonus and any winnings it produced.
Bonus play should stay fun. You must be 18 or over, and you can set deposit limits in your account. If gambling stops feeling like a game, BeGambleAware offers free support and GamStop lets you block yourself from UK-licensed sites.
