1.21 Gigawatts

Reviewed by Paul Clare Last updated:

Where we're going, we don't need roads and we probably don't need reels either if my previous experience of Rogue games is anything to go by. 1.21 Gigawatts should be just enough power to get your balance moving towards a 5,000x max win, base game modifiers and a generous portion of free spins.

1.21 Gigawatts Review

Tired of standard slot mechanics and predictable bonus games? It might be time for you to walk away from other game developers and run towards Rogue. These guys always push the limits and this is great news for any slot fans who’d like to follow them on their quest to deviate from the standard.

Gameplay & Features

Once again, Rogue is turning away from regular paylines with the introduction of Turbo Reels.

Everything looks fairly tame as you take on the five reels and three rows, but then you look towards the dials at the bottom of the screen. 

These dials will increase wins with a multiplier or split reels and give your bonus entry an extra boost. 

Regular payouts are determined by landing groups of three, four or five royals or picture symbols. The royals pay up to 0.5x and the pictures pay up to 5x. Wild symbols substitute for others, except bonus symbols, and payout in their own right for a group of five. 

As you spin, the dials will fire up some multipliers worth up to 10x and if you hit a win, the multiplier is applied. Split reels will stretch up to five reels with extra symbols on them to create the maximum number of paylines

Bonus Game

Entry into the bonus game happens when three, four or five bonus symbols hit the reels. If the triggering spin does not contain any bonus boost, you'll have between 5 and 15 free spins, depending on how many scatters you land. 

Increasing the booster means an increased number of spins. If you can hit the top boost with five scatter symbols, you'll get 25 free spins. 

Revving up the Wild Dial brings extra wild symbols to the reels during the bonus game and this can help accumulate extra wins where you didn't think they were possible. 

Boost symbols move your car along the track and when you reach a checkpoint, you'll receive more spins.

The bonus game can take a long time to complete and you certainly feel like you’re getting value for money at that point! I enjoyed it for the most part but I think I had nearly 30 spins by the end of it and that kept me occupied for quite a while. I managed to sign for a takeaway delivery, unpack all the food and start my lunch before it came to an end.

At the end of it, I had well over 300x in the bank and that seemed like a pretty good return. It was thanks to the split reels combining with those wild symbols.

Turbo Reels

Each spin can up the ante by creating 3 special modifiers. There’s a possible multiplier worth up to 10x, a reel splitter that can produce the max 7776 win ways and a bonus boost, which determines how many spins you might get if you trigger the bonus game.

Free Spins

3, 4 or 5 bonus symbols get you between 5 and 25 free plays. Boost symbols get you moving along the track and can award more free spins and the Wild Dial will release extra wilds onto the reels.

Win Potential

I haven't received word of an official volatility rating for this slot yet but my experience puts it somewhere down the middle in the medium category. I saw regular wins and they would generally be of pretty decent value.

Triggering the bonus game wasn't like trying to purchase unicorn manure and the additional modifiers aren't exactly shy either. The RTP of 94% might not please some, but the potential to hit 5,000x is here and that should keep everybody happy.

Design

You’ll witness an animated, cartoon visual, which takes you back to the 50s when the Back to the Future saga began. As you drive through the streets, buildings flash past and the dials at the bottom of the reels make you feel like you're sitting in the DeLorean. 

I'm not sure if 1.21 Gigawatts should perhaps carry a health warning though for people with epilepsy – it made my eyes feel very strange after I'd been playing for a while! 

The game's symbols are synonymous with the movie series and you even hear the engine rev as the dials get moving. I wasn't a huge fan of the soundtrack, but that's just a personal preference.

Our Verdict

The aim of the game is to take this time machine to Utopia and witness one of the lengthiest bonus games I’ve had the pleasure of playing. The base game is great fun and there's more than just a hint of Back to the Future about this slot from Rogue.

Anyone who loves the film will find a lot here to amuse them and fans of interesting add-ons can also scratch a certain itch at the same time.
