Casushi sign-up: mobile check and WELCOME2026 timing
Registering at Casushi takes about three minutes if you have the right details to hand, but two steps in the flow trip up more new players than anything else: the mobile number field and the promo code box. Get those right and the rest is routine. This walkthrough covers the exact sequence, what the 40 free spins welcome offer requires, and how the WELCOME2026 timing works so you do not lose the bonus before you have even spun a reel.
Before you start: details, deposit and the mobile number rule
Casushi is operated under a UKGC licence held by Solaya Group Limited, so registration follows standard UK verification rules. Have your full name, date of birth, home address and a payment method ready. You will also need a mobile number, and this is not a cosmetic field: the registration form requires it for verification, and it is how the account gets confirmed during sign-up. A landline will not do, and neither will a number you share with someone who already holds a Casushi account.
On money, the Casushi welcome offer requires a £10 deposit and £10 staked on slots before the 40 free spins on Big Bass Splash are triggered. That is a qualifying spend, not a fee, but it does mean the bonus is not sitting in your account the second you register. Budget the £10 deposit and plan a short slot session of at least £10 in stakes, then the spins land. Free spin winnings are paid as cash with no wagering, which is the standout term here. No playthrough means what you win from the spins is withdrawable, subject to the usual verification checks.
One more thing to sort before you touch the form: the promo code. Casushi uses the code WELCOME2026, and the registration page is the only place it can be applied. There is no retroactive option. If you create the account without typing it into the promo code field, support cannot bolt it on afterwards and you will be looking at the standard sign-up route instead of the coded offer. Keep the code in a note on your phone so you are not hunting for it mid-form.
The registration walkthrough, step by step
Open the Casushi site or the Casushi app in your browser and hit the register button. The first screen asks for an email address and a password. Use an email you actually check, because verification links and withdrawal confirmations go there. Pick a password you do not reuse on other gambling accounts, then move to the personal details screen: legal name exactly as it appears on your bank account, date of birth, and full address including postcode. Mismatches here are the most common cause of a stalled first withdrawal, so slow down for thirty seconds and type it properly.
The next screen is where the mobile number goes. Enter a UK mobile you control, because Casushi sends a verification code by SMS and you will need to key it in to finish. If the code does not arrive within a couple of minutes, check the number for typos before requesting a resend, and request resends sparingly. Casushi online offers additional context worth reviewing. Repeated requests can lock the step temporarily. Once the SMS code is accepted, you will reach the promo code field. This is the moment: type WELCOME2026 exactly, all capitals, no spaces before or after. The field is easy to skip if you are tapping through quickly on a phone, so check it has registered before you confirm.
Finish by setting your deposit limits. Casushi, like any UKGC-licensed operator, must offer them at sign-up, and setting a monthly figure you are comfortable with now saves friction later. Accept the terms, confirm the account, and you are in. From there, make the £10 deposit using a debit card or another supported method, stake £10 on slots, and the 40 free spins on Big Bass Splash are credited. The games lobby is broad: slots, live casino, roulette, blackjack and game shows, so if Big Bass Splash is not your thing, the qualifying stakes can go elsewhere, but check the offer terms for any game-weighting exclusions before you pick.
After sign-up: bonus timing, verification and getting paid
The welcome offer is not the only reason to log in during your first week. Casushi participates in Drops & Wins 2026 and runs a daily promotional game called Daily Catch, both of which reward regular play without extra deposits. Treat them as a reason to check the promotions tab each morning rather than a strategy. On the bonus itself, the sequencing matters: register with WELCOME2026, deposit £10, stake £10 on slots, then the spins appear. If you deposit before registering the code, the offer will not attach, and there is no fix afterwards.
Verification is the other timing issue. UKGC rules mean Casushi will ask for ID and possibly proof of address before your first withdrawal, and free spin winnings paid as cash still pass through that check. Upload documents early, ideally the same day you register, so a withdrawal request does not sit in limbo. The Casushi guide covers withdrawal times and payment methods in detail, and it is worth a read before you request a payout so you know which methods clear fastest and whether any fees apply. Debit card withdrawals typically land in one to three working days; e-wallets can be quicker.
If something goes wrong, the support team handles account issues, but be realistic about what they can and cannot do. They can resend verification codes, chase a missing bonus, and talk you through the casino payment methods on offer. They cannot add WELCOME2026 to an account created without it, and they cannot waive the £10 stake requirement. That is why the two-step discipline at registration, correct mobile number and code entered at the right moment, is worth more than any support ticket. Keep your login details and the SMS-verified number consistent, and the account runs smoothly from day one.
To sum up the practical route: have your mobile to hand, enter WELCOME2026 in the promo field during registration and nowhere else, verify the SMS code, set deposit limits, then deposit £10 and stake £10 on slots to unlock the 40 free spins on Big Bass Splash. Check the promotions tab for Drops & Wins 2026 and Daily Catch, upload ID early, and read the withdrawal guide before your first cashout. Do those things in that order and the Casushi sign-up is a five-minute job with no loose ends.
