What this means for players

Same owner often means the same terms, the same support team and the same payout rules. A self-exclusion at one brand may not cover its sister sites. Check each brand’s terms before you rely on a self-exclusion; a national scheme (such as GamStop in the UK or Spelpaus in Sweden) covers every licensed site in that country.
