PokerStars.pt is the Portuguese, SRIJ-licensed instance of PokerStars. Unlike most fully ring-fenced national markets, it shares liquidity with Spain, giving it noticeably deeper traffic than a Portugal-only pool would have on its own.
At NL100 and below, traffic is strong and games run soft. Above NL200, tables get thinner โ you'll still find a handful of tables a day with decent fish and weak regulars, just not the constant action you'd see at lower stakes.
