How to Play

Because this is a fixed payline slot, it's very easy to play. You can't change the paylines you bet on - you'll always be playing with all 40 paylines active. This means you only need to change your bet size. Bet amounts will always be a multiple of 40, but your bet per line will change. You can see the full paytable in the game menu.

Here are some step-by-step instructions to help you get started.

1. After launching the game, click on one of the arrows on either side of the total bet amount display. The arrow on the left will decrease your bet, while the arrow on the right increases it. Scroll through the available bets until you find the amount you're happy with.

2. Once your bet size is correct, hit the spin button to set the reels in motion.

And that's it! This is a very simple game to play.

There is also an autoplay function that you can activate by clicking on the autoplay button (two arrows in a circle formation). This allows you to set up a number of bets to play automatically. You can stop the autoplay function at any time during play.

In order to win, you need to land three or more matching symbols on an active payline. All wins pay from left to right, starting on the leftmost reel. There is a wild symbol that can appear stacked and multiple times during one spin, giving you lots more chances to win. It's also possible to win on multiple paylines in a single spin.

Bonus Features

This game has two main bonus features. The first is the free spins feature. This is triggered by landing three scatters anywhere on reels 2, 3 and 4. You can read about the free spins in detail below. The second bonus feature is the reveal-a-wheel bonus. There are several signal symbols in the game, each with its signal pointing in a different direction. Some of these only appear on certain reels. When these signal symbols appear in a certain combination, the reveal-a-wheel bonus feature is triggered. This bonus feature can appear on reels 2 or 4, or on both at the same time. Reveal-a-wheel launches a special wheel that awards multipliers of up to 200x.

Free Spins

In order to trigger the free spins feature, you need to land three scatters anywhere on reels 2, 3 and 4. The scatter can only appear on these reels. As well as an instant payout, you'll also launch the free spins game. This is played on different reels to the base game and offers the chance to land some big wins. You'll be given seven free spins, but unfortunately the free spins feature can't be retriggered.

Our Verdict

8/10. This is a smooth, attractively designed slot that's easy to play. With a free spins bonus round and the reveal-a-wheel bonus, there's plenty to keep things interesting. Perhaps an under-rated feature, however, is the stacked wilds. If these land in the optimal position, especially on more than one reel, you can scoop some impressive wins in both the base game and the free spins game so keep your fingers crossed for these.
