Now I've played the game, my feelings are somewhat mixed. Presentation wise this is a definite step up in quality from many Playtech slots. The sound is particularly good for this developer and the graphics looked fantastic, particularly when I tried the game on the super bright screen of my tablet.
I was eager to see the bonus rounds, but there only turned out to be one feature to play for - it had a lot riding on it! Again, once I'd had it a few times I was left with somewhat mixed feelings. Whilst in the first game you got to choose from a selection of potions to determine how many free spins you would receive, and at what multiplier, this time around you get an ascending multiplier of up to 5x that increases after every two free spins. This is fine, but you get a fixed ten free spins which cannot be retriggered and with only a couple of spins at the top 5x multiple, you really do not to get lucky at just the right time.
I guess I was just expecting a lot more from this game, and now I've played it a lot I really think I still prefer the first game overall. I like the double height character symbols and the fact you are guaranteed a few spins with a decent multiplier during the free spins, but there are plenty of games that just award a 5x multiplier for the whole of the ten free spins - after all you are likely to get several blanks during any given bonus round anyway.
