Having grossed over $585 million in box offices, Iron Man is no doubt one of the most successful movies of all-time. Not surprisingly, the movie-based Iron Man slots is one of the most popular slots games ever. 

A big reason for the popularity of Iron Man slots is that some of the symbols bear striking resemblance to the movie characters. For example, Robert Downey Jr. (Tony Stark) is found on the reels along with various poses of his Iron Man suit. You can find out about the other aspects that make this 5-reel, 25-payline game special in our Iron Man slots review.

Betting Options and Payouts

Like many other Playtech-designed games, Iron Man slots gives players the option of betting between $0.01-$5.00 per coin. You can also put up to 10 coins on each payline, which makes for a maximum possible wager of $1,250 when all 25 paylines are taken into account.

Symbols that make payouts include Tony Stark, Iron Man logo, Iron Man flying, glowing Iron Man, A, K, Q, J, 10 and 9. The lowest possible payout of 7 coins comes when you either get three 9's or 10's in an active payline. The highest possible regular payout of 5,000 coins is made if you can get either Iron Man flying or the glowing Iron Man symbols five times in a payline.

There are also four progressive jackpots (Power, Extra Power, Super Power, Ultimate Power) available, and these can be won through a randomly triggered game. The game sees you choose squares on a 4x5 grid to reveal which jackpot you win.

Wilds, Scatters and Bonus Games

Both the Iron Man flying and glowing Iron Man symbols serve as expanding wild symbols. These symbols become expanding wilds when they appear stacked on reels 2, 3 or 4; when this happens, they explode across the reels and help you form lots of winning combinations. The Iron Man logo is the scatter symbol, and your payouts will be multiplied by the following amounts when these logos appear on the reels:

2 symbols = 1x
3 symbols = 3x
4 symbols = 10x
5 symbols = 100x

In addition to being a scatter symbol, the Iron Man logo also unlocks the "Missile Attack" bonus game. As the name implies, the goal of this bonus game is to help Iron Man stop missiles that are heading towards the city; the more missiles you stop, the more free spins you get to make. In the second part of the bonus game, you put these free spins to good use by seeing what prizes you can win on the reels.

Mixed Pay

One more point worth covering in our Iron Man slots review is the mixed pay feature. What mixed pay amounts to is a multiplier that's based on how many Iron Many flying or glowing Iron Man symbols you can get on reel 1, reel 2, etc. You can earn multipliers that include 8x, 30x, 150x and 750x.

Looking at our Iron Man slots review from a broad perspective, this is certainly an enjoyable game that does a great job of incorporating elements from the movie into the slots world.
