Red tiger plays out as soon as you close the game, novo lasts 20 mins (I think?) And yggdrasil save for 10 mins as far as I’m aware. Looked else where and found that merkur bonuses can be saved too, so I would stick with PnG, BTG, netent, thunderkick, push gaming, microgaming, quickspin, WMS. Not sure if IGT saves either, but at least you know to avoid red tiger, novomaticΒ and yggdrasil π
