I used to enjoy doing bonus hunts. Check with the casino first on live chat to see if your aloud, don’t want to get a big hit then find out it’s void. I don’t think novomatic bonuses save, when you get a bonus on a blueprint and close the game I think it updates your balance as they are predetermined. My favourite providers was micro gaming and BTG so these was mainly included in my bonus hunts. Immortal, finer, bust the bank, DHV, temple quest, donuts etc. I could usually get around 10 bonuses with a £400 balance £0.90-£1.20 stake. The key is don’t chase a bonus or you’ll end up ripping with only a few bonuses. I used to put about 50 spins through a game, if the balance was holding I’d carry on for a bit, if it was ripping I’d move on to the next game. I suppose different things will work for different people, it’s all about luck.
