Help me please, do I have to put stodlinjen.se in any bonus offer or not?

According to Come On Connect Advertising Guidelines for our se licensed brands:
The following must be clearly stated on your website/s and included in emails and SMS send outs where our brands ComeOn!, Mobilautomaten, Snabbare, Hajper, Svea Casino, CherryCasino, Casinostugan.
  • 18+
  • stodlinjen.se
  • Please gamble responsibly! (SE: spela ansvarsfullt)
  • Terms apply! (SE: Villkor och regler gäller)
  • The significant bonus terms and conditions must be clearly stated.

I can't straightly recognize is it enough to past just text "stodlinjen.se" or I have to build complete link.
Other players are doing completely different ways.
For example:
CasinoFeber - just text
SpelSidor do it like nofollow with anchor "18+ | Spela ansvarsfullt"
What is the most correct way for my recourse - meracasino.se?
