A person limit and a household limit can both apply
One per person limits what you can claim. One per household can cover everyone living with you. If an offer lists both, both apply, so don't stop reading at the first rule your account passes. Hercules, for example, lists person, account, address, computer and IP all at once.
The same goes for address, device, IP, payment method and contact details when the casino lists them separately. A new email address doesn't answer an address limit, and a verified ID doesn't cancel a shared-device rule.
The account question and the bonus question are separate
Some questions are about whether each adult can have an account. Others are about who gets a particular bonus. Ask both when they matter. A support reply letting two people at one address register can still leave the household bonus limit unanswered.
Read the offer's own terms alongside the general bonus and account rules. If they seem to clash, screenshot both and ask the casino which one applies to your bonus. A reply about a different offer isn't a safe stand-in.
Shared details need a clear answer
Household and address are the casino's words to define, not yours. Student halls, shared houses and short lets raise questions a postcode can't answer. Describe how you really live, rather than picking a definition that makes a second claim look allowed.
Don't assume every brand run by the same company shares one bonus allowance, or that each brand has its own. Check what this offer says. America777, Europa777 and Canada777 share a code, for example, but each casino counts its own free bonus. We can't vouch for any group-wide policy.
The other bonus rules still count
Settling the household question doesn't confirm your age, location or new-customer status. It doesn't remove the game rules, the maximum bet, wagering, cashout caps or expiry deadlines either.
A no-deposit bonus can still need ID checks or a payment before the payout, like Yabby's US$20 verification deposit. Read those rules separately, and don't treat a yes on the household question as a promise you'll get paid.
