The base game has 3 scatter symbols to watch out for - these are Mark 42, War Machine and Iron Patriot. If the marker 42 appears on the reel 1, the War Machine appears on the reel 3, and the Iron Patriot appears on the reel 5 at the same time, and you will trigger the All Systems Go Re-Spin function. They will stay on the reel and give you 1 re-spin.

The graphics are excellent, and it takes a long time to trigger the Hall of Armour free game feature. Once entered, the reward is not just to prove waiting (in my opinion). Every time I choose the Iron Man Mark 42 free game feature, because this can bring you a huge victory (although not often). If you get 5 wilds on all paylines, you will earn 2,500 times the bet. However, this possibility is very small. If you are looking for a better Marvel game, I recommend the Fantastic Four or the Avengers.
