The highest paying icon in Stunt Pilot is the substitute and while this icon will not appear on the reels with every spin, when it did show for me they came in groups thankfully and I once managed landed myself with with four of these and got a pretty big win. I wasn't playing this game on the highest bet but the winnings kept me going and I ended up leaving with some change left.
I also managed to unlock the stunt feature in this game on a couple of occasions by landing three or more scatters on the reels. This game involves picking a trick to complete which is awarded a cash prize, I wouldn't too excited about this feature to be honest as nothing big ever came from it for me.
Trying my best not to be in any way bias while rating this game and taking it for what it is I am going to give Stunt Pilot a rating of 5/10.
