Guardian Bonus in the Avatar's Gateway Guardians slot at American Luck

I recently returned to Avatar’s Gateway Guardians at American Luck, a game that my colleagues and I often played. To be honest, I was most drawn to the Guardian Bonus feature. Does anyone else like it? At first, the game seems like just a cascading slot with portals. However, when part of the avatars gateway guardians slot is activated and a specific Guardian’s bonus is triggered, that’s when the fun really begins! I especially liked the random multipliers and expanded wilds in this slot, which can cover part of the reels and dramatically increase winnings. Each Guardian has its own style, so the bonuses feel different. Does anyone else actively play this slot? Which Guardian do you like the most, and how often do you fully activate the portal?
