BTW, is it normal to bet x200 spins and not get any free spins at all (the game I played today was Viking Forge)?
This is not a matter of normal or not, maybe you are unlucky, if you are lucky then you can get a freespin bonus with just 10 or 20 spins, but this rarely happens. If you play on a slot machine that has a buy freespin feature, you can combine it with normal spins and buy free spins. Usually I do it like that, about 10 or 20 normal spins and if the results are bad I will buy free spins, if the results are still bad you can try another slot machine.
In fact it is the game that gave me max win 4-5 times within a week few years ago.
Seriously? you get maxwin up to 5x a week? that's crazy guys. Now it's very difficult to get Maxwin on PP, the last time I got maxwin was about 2 years ago. Pragmatic slot machines are now brutal
