Two people share a home Wi-Fi network, both sign up at TonyBet, both enter the same tonybet promo code, and one account gets flagged for multi-account review while the other sails through. The difference usually is not the IP address. It is the browser fingerprint sitting behind it. TonyBet OÜ pairs IP logging with canvas fingerprinting on the main site, and that combination decides whether your WELCOME2026 funds stay liquid or get frozen pending review. Understanding how the check actually works lets you set up a shared household correctly instead of guessing.
How TonyBet’s shared-IP detection actually works
An IP address is a blunt instrument. Families, roommates, dorm floors, and coffee shops all funnel multiple players through one public address, so a platform that banned every duplicate IP would lose legitimate customers by the thousands. TonyBet OÜ knows this, which is why the risk engine treats IP as one signal among several. The second signal is a canvas fingerprint: a hash built from how your specific browser and graphics stack render hidden text and shapes. Two devices almost never produce identical canvas hashes, even on the same model, because driver versions, fonts, and GPU behaviour vary.
The practical consequence is counterintuitive. Two players behind the same IP address pass review cleanly when they use different browsers and different devices. One player on Chrome for Windows and another on Safari for an iPhone looks like exactly what it is: two separate people. The flag fires when the fingerprints converge. Identical browser versions on the same IP, especially the same Chrome build on two similar machines, produce near-matching canvas output, and that pattern reads as one person opening a second account to farm the welcome offer twice.
When that match triggers, the multi-account review can freeze WELCOME2026 funds and any winnings tied to them while the operator asks for ID. The promo code itself is not the problem, and neither is the one at https://tonybet-casino-online.ca/promo-code/. The promo code does not bypass minimum deposit limits or house wagering rules, and it certainly does not bypass identity checks. A frozen balance during a shared-IP review is an identity verification issue, not a code issue, and treating it as one saves you a lot of confused support tickets.
What the canvas hash sees that your IP does not
Your IP tells TonyBet where the connection originates. Your canvas hash tells it how the machine is configured. Put together, the pair distinguishes „two roommates“ from „one person with two accounts“ with reasonable accuracy. A few configuration details shift the hash enough to matter: browser brand, major version, operating system, screen resolution, installed font set, and whether hardware acceleration is on. Two laptops bought in the same year and set up with default settings are the risk case. A gaming desktop and a phone are the safe case.
This is also why VPNs do not solve the problem and often make it worse. A VPN changes the IP but leaves the fingerprint intact, so a player who forgets to disable it on one device can create an artificial overlap that looks like spoofing. If you share a connection with another TonyBet player, the goal is differentiation, not concealment.
Setting up a shared household so WELCOME2026 clears review
Start with the accounts themselves. Each player registers separately, enters WELCOME2026 in the registration form or the cashier deposit field on their own account, and deposits from a payment method in their own name. The welcome package requires a minimum deposit of C$20 per tier, and the multi-deposit structure means each tier should be funded by the account holder. A shared credit card funding two accounts is the single fastest way to turn a routine fingerprint check into a full documentation request, because payment identity is a stronger signal than IP.
Then separate the browsers deliberately. If one player uses Chrome, the other should use Firefox or Edge, and ideally on a different device. Do not clone a browser profile to a second machine, do not sync settings across devices under one Google or Microsoft account if you can avoid it, and do not install the same extension set on both. These steps push the canvas hashes apart and make the two accounts read as two people, which is what they are.
Age rules vary by province and are worth confirming before anyone registers. Players in Alberta, Manitoba, and Quebec must be at least 18 years old. Players in the rest of Canada must be at least 19 years old. Ontario residents have a separate path entirely: TonyBet Ontario operates at tonybet.ca under provincial oversight, does not advertise welcome packages, and runs under iGO rules that differ from the TonyBet OÜ site used by players outside Ontario. If you are in Ontario, the WELCOME2026 flow described on tonybet-casino-online.ca does not apply to you, and the provincial site will not honour it. A household split across provincial lines should expect each player to use the correct site for their location.
If a review does land, respond with documents rather than arguments. Send government ID for each account holder, a utility bill or lease showing the shared address, and proof that each deposit method belongs to its account. Support can see the IP overlap and the fingerprint match, so denying the shared connection wastes a round trip. Explaining it directly, with two IDs at one address, resolves most of these cases within a few business days, and the WELCOME2026 funds are typically released once identity is confirmed.
Keep a short checklist in mind before the first deposit: one account per adult, one payment method per account, different browsers and devices, no VPN, and the correct site for your province. Enter WELCOME2026 once, in the right field, after you have confirmed the minimum deposit for each tier you plan to claim. Households that set up this way rarely see a review at all, and when they do, the paperwork is already on hand. The tonybet promo code canada players ask about most often is not the fragile part of the process. The fingerprint match is, and that is entirely within your control.
