Oshi Casino Welcome Bonus UK 2026
Deposit £100 at Oshi Casino and you start with £200 plus 100 free spins. The Oshi Casino welcome bonus matches your first deposit at 100% up to £400, so a bigger deposit buys a bigger balance and a bigger wagering target. Before you pay in, check the licence: Oshi Casino holds a Curaçao licence and has no UKGC licence. The Gambling Commission does not oversee the site, and a GamStop registration does not block your account there. If you self-excluded through GamStop, stay away.
Oshi Casino Welcome Offer in Numbers
The Oshi Casino welcome offer covers your first deposit. You pay in at least £20, Oshi Casino matches it 100% up to £400, and the cashier adds 100 free spins on a slot named in the promotion. The bonus funds carry 40x wagering. Oshi Casino changes these figures from time to time, so confirm them on the promotions page before you deposit.
| Your deposit | Bonus (100%) | Starting balance | Wagering at 40x |
| £20 | £20 | £40 | £800 |
| £100 | £100 | £200 | £4,000 |
| £250 | £250 | £500 | £10,000 |
| £400 | £400 | £800 | £16,000 |
Take the £100 row. You wager £4,000 before the bonus winnings become withdrawable. At £1 a spin that means 4,000 spins, and at 50p a spin it means 8,000.
Oshi Casino Welcome Bonus Code and Sign Up Steps
Register with your legal name, date of birth, email address and home postcode, then confirm your email through the link Oshi Casino sends. Open the cashier and choose a deposit method. Visa and Mastercard debit cards work, and Open Banking appears in the cashier for some accounts. UK rules ban credit cards for gambling, so Oshi Casino cannot accept one from you.
If the cashier shows a bonus code field, type the Oshi Casino welcome bonus code from the promotions page and confirm the payment. If no field appears, tick the welcome offer box before you pay. Skip that step and the deposit lands as plain cash with no bonus, and support may refuse to backdate it. Keep the welcome code open in another tab so you can paste it straight in.
Oshi Casino credits the bonus funds and the 100 free spins to your account after the deposit clears. Upload your passport or driving licence and a recent proof of address before you ask for your first withdrawal. Verification takes a day or two, and you do not want that wait stacked on top of a payout request.
Wagering, Game Contribution and Bet Caps
The 40x applies to the bonus amount. Slots count 100% towards it. Blackjack, roulette and live dealer tables count for a fraction, or for nothing, so a £100 stake on blackjack barely dents the total. Stick to slots while a bonus is live.
A maximum bet cap applies while bonus funds sit in your balance. If you break it, Oshi Casino can void your winnings, so read the exact cap in the terms before you raise your stake.
Free spin winnings carry the same 40x. One hundred spins at 20p stake £20 in total. Win £25 from them and you owe £1,000 of wagering before you can cash that £25 out. Use the spins and finish the wagering inside the expiry window printed on the promotion, because unused spins and unfinished wagering vanish when the window closes.
Is the Oshi Casino New Customer Offer Worth Claiming?
The 100% match is generous, and the £20 minimum keeps the entry cost low. The 40x wagering sits at the industry average, so I would not call it a bargain. A 50p slot session to clear £4,000 takes hours, and you will probably burn through part of the balance on the way. If you want to cash out quickly, decline the bonus and play with your own money. If you enjoy long slot sessions and have a week of evenings free, the Oshi Casino sign up offer gives you extra spins at no extra cost.
A £4,000 wagering target on a £100 deposit tempts you to chase losses. Set a deposit limit in your account before the first payment and keep to it. The National Gambling Helpline (0808 8020 133) and BeGambleAware offer free, confidential support if gambling starts to cause you stress.
