Here is my entry,
171,60x (0,5e stake)
I ran it about 1000 spins on play money and perhaps 300 spins real money, a few bonus buys.
I rate it 7/10, it gives a decent run for the money and quite innovative with two bonuses. Nevertheless, it is a hit&run slot, but much better than the Jammin 2 disaster.
It would be more playable without 50kx max win. With this level of volatility, 10kx would be enough while 50kx could only be accessed with buying a super bonus. Furthermore, it is a bit tedious spinning for the typical 5-20x bonuses, yet better than JJ2 5-10x returns in 95% of bonuses.
