It’s a hard block right at the date of birth field, learned that firsthand testing it with a fake younger birthdate. Form flat out refused to submit and threw up a message saying the minimum age wasn’t met, no way to bypass it or continue past that screen. Tried again with an accurate adult birthdate right after and the rest of signup went through normally without any further age related friction. Verification later on when withdrawing did ask for an ID photo too, so the date of birth field isn’t the only checkpoint, just the first one. Looked into the terms page on nightwin.uk.com out of curiosity afterward and the eighteen plus requirement is stated clearly near the top, not buried anywhere. Genuinely enforced, not just a formality
