What this slot is
Grizzly Slots states it in one pass. Mad Jack Hold & Win is a 1spin4win slot. Canadian players open it at Here2Win Casino. This page does not add a rating.
Grizzly Slots keeps Mad Jack Hold & Win on a Canadian host so the wording stays in Canadian English: slot, player, C$. The Australian catalogues use their own wording on purpose. Same brand on the button, Here2Win Casino, different page.
If you only needed the studio, it is 1spin4win. If you needed the RTP, it is on the fact list when the card has it. The rest of the 1spin4win slots are one click away on the provider page.
The same studio page names Lucky Tribe 20 and then 10 Lucky Spins.
