Three deposits earn you the full Oshi Casino bonus package, and the first one carries the biggest match: 100% up to £500 plus 100 free spins. Reload offers, cashback and slot tournaments follow, and most of them credit without a code.
Oshi Casino Welcome Package
Your first deposit of £20 or more gets a 100% match up to £500, with 100 free spins added to your account. Put in £200 and you start with £400 in total. Oshi sets a 40x wagering requirement on the bonus amount, so a £200 bonus means £8,000 in bets before you can withdraw it. Winnings from the free spins carry the same 40x requirement.
Your second deposit earns 50% up to £300 plus 50 free spins, again from £20. The third deposit earns 75% up to £200 with no spins. Each stage has its own 40x requirement and its own 7-day clock, so a bonus you ignore for a week disappears.
You can fund the account with a Visa or Mastercard debit card, Open Banking or crypto. UK rules ban credit cards for gambling deposits, so the cashier will not accept one.
Oshi Casino Bonus Codes
The welcome package needs no code. You tick the bonus box in the cashier before you pay, and the match lands in your balance once the deposit clears. Reload promotions sometimes ask for a code, and you find those on the promotions page, in Oshi's emails or by asking live chat.
Oshi Casino bonus codes expire, so copy a fresh one the same session you plan to deposit. Type it into the promo field before you confirm the payment. A code entered after the deposit does nothing, and support cannot add it back afterwards.
Cashback and Reload Offers
Cashback on Net Losses
Oshi returns 10% of your net losses at the base loyalty level, and the rate climbs towards 20% as you move up the VIP ladder. Lose £300 across a week at the base level and £30 comes back to your balance. Check the wagering attached to cashback before you spend it, because Oshi may treat it as bonus money.
Reload Bonus
The midweek reload gives you 50% up to £200 when you deposit £30 or more. You can claim it once per week, and it uses the same 40x requirement as the welcome stages. Reloads come and go, so open the promotions tab before you deposit.
Free Spins and Tournaments
Oshi schedules slot tournaments with leaderboard prizes, and your spins on qualifying games earn the points. Free spin drops arrive by email to active accounts. Both pay out in bonus funds unless the promotion page says cash.
How to Claim the Oshi Casino Bonus
Register with your email, confirm the link Oshi sends and open the cashier. Pick the welcome bonus, choose a debit card, Open Banking or a crypto wallet, and deposit at least £20. The match and the free spins appear in your account as soon as the payment clears. If nothing shows after ten minutes, message live chat with your transaction reference.
Keep one active bonus at a time. A second claim while the first is live can void both, and Oshi can cancel winnings from any round above the £5 stake cap.
Play Within Your Limits
Oshi holds a Curacao licence, not a UKGC licence, so GamStop self-exclusion does not cover your account there. If you have signed up to GamStop, respect that decision and stay away from sites outside it. Set a deposit limit before you claim any offer, and treat a 40x requirement as a cost, not a gift. BeGambleAware offers free support on 0808 8020 133, and you must be 18 or over to play.
