It was almost certainly a deliberate decision by GG Poker to never offer traditional SnGs. The game format has gotten less and less popular over the last several years.
888 Poker has just removed their SnGs entirely, and the selection and volume on sites like PokerStars and
partypoker is nowhere near, what it once was. Unless this overall industry trend changes, which is entirely up to players, then I dont see any chance, GG Poker will try to move against it.
GG Poker have 6-handed spins, which are essentially the same as a 6-man hyperturbo on PokerStars. So this is pretty much your option, until perhaps PokerStars become available to you again. As I understand it, PokerStars are undergoing some sort of sit-out period in
nederlands as a penalty for operating unlicensed, but that might soon be over. I am sure PokerStars ambassador Lex Veldhuis is waiting with excitement for that, so he can stop renting an apartment in Belgium to do his job and stream.
And if you cant wait for Stars to come back to Nederlands, most likely "grey" sites like ACR are also available, and ACR have lots of SnGs. Just be aware, that there are more problems getting money out from grey sites than from regulated sites, since unsurpricingly our governments are trying to make it difficult for us to play there. Most likely you will need to resort to getting paid in crypto currency. So just be aware of this, and dont deposit more, than you need to play for maybe a few days at a time.
