Thor The Mighty Avenger Slots

Thor Slots is a five-reel video slots game with 30 pay lines and you must play all 30 lines. The machine allows just one coin per line, but coin sizes range from £0.01 to £5. The minimum bet is £0.30, and the maximum bet is £150.

To start, simply set the line bet and then click Spin. Since the pay table scales evenly, the $0.30 minimum bet is a viable option for low rollers. For players that want to maximize their odds, bet as much as your bankroll allows because it increases your chances at the progressive jackpot. In other words, the odds for one spin at £150 are significantly better than two spins at £75 per.

Below the reels are a series of buttons that you use to control the game. The Info button reveals the pay table and other information, and the plus and minus buttons let you adjust the line bet. There is no button to adjust the line count because this game requires all 30 lines to be active each spin. The Autoplay button activates an auto-play mode that can be set to a spin count or simply toggled to “until.” Until occurs when you win, hit a feature or click the Stop button. The Spin feature initiates a standard round, and it’ll serve as the Stop feature during toggled auto-play.

As with all Marvel slots by Playtech, Thor Slots is linked to the Marvel progressive jackpots.

Thor Slots Bonus Features

The Thor symbol serves as the jackpot symbol and the wild symbol. Thor can appear on all reels, and it launches a Thunderstorm Respin when covering the second reel and a Lightning Free Spin when covering the fourth reel.

So, if three Thor symbols appear in the second reel, the Thunderstorm Respin will automatically occur, spinning the reels but leaving all three wild symbols in reel 2, giving you a great chance of winning on the respin.

If three Thor symbols fill the fourth reel, you will automatically trigger the Lightning Free Spin – where you will receive one free spin, but with between 2 to 5 wild symbols appearing on the board. This is another great opportunity for an easy win.

If the Heimdall bonus symbol covers the third reel, it awards free games via the Rainbow Bridge feature. Get 3 of the bonus symbols on the third reel and the bonus game is launched – putting you on the Rainbow Bridge, with Heimdall the gatekeeper. You will have to choose between two planets and then either play the Earth free games or the Jotunheim free games – which offer some different rules and symbols!

The free game mode continues until the Heimdall bonus symbol covers the third reel in both the Earth and Jotunheim versions, at which point you are returned to the Rainbow Bridge.

When playing the Earth free games, you will encounter the evil Destroyer. And in Jotunheim, expect to see the Frost Giant ruler Laufey.

All Marvel slot games by Playtech are linked to a series of progressive jackpots. The largest of the jackpots is Ultimate Power, which has paid out in excess of a million dollars. In descending order, the other available jackpots are Super Power, Extra Power and Power. Each time you spin on a Playtech Marvel slots game, you have a shot at each of these jackpots, and your chances are determined by the size of the overall stake.

Graphics, Animation, Music & Sound Effects

The video, artwork and on-the-reels animations are all top notch. The art is so photo-realistic that it appears straight out of the movie. The best effects occur when the bonus features are hit, animating Thor or one of the other characters.

The music used for Thor is a bit subdued for such an epic adventure and may disappoint arcade players, but it’s a solid design choice for a game that aims to keep gamblers playing for as long as possible. The sound effects are diverse and all high quality, and you can easily disable them using the speaker icon at the top of the screen.
