Twisted Lab RotoGrid Review

You have to hand it to Hacksaw Gaming - this developer loves to put its own twist on things and this time I mean that in a literal sense! I've not seen reels move like this before (not with such high frequency, anyway) and it could be a fantastic new way of landing big wins.

Gameplay & Features

It's not completely different, but it's a new way of looking at a standard set of reels! This game crosses a grid with standard reels and you could find wins on any side.

The RotoGrid symbols turn the grid between 1 and 4 times and this could align some of the symbols along one of the 19 pay lines as it happens. At the same time, any beakers on the screen will tip their contents to the bottom of the grid and create some wilds in the process. Standard wins are made up of low, medium and high-paying symbols with the best results being 10x for the beakers. Medium symbols can fetch you up to 5x and the low payers get you 1x for a group of 5 mushrooms.

Bonus Games

If you are lucky enough to see 3 scatter symbols, you'll fetch 10 free spins and now there's a much better chance of seeing the RotoGrid symbols and Oozing Beakers. This means that you could see extra wins and more wilds to contribute towards those wins as you play through the bonus game.

Landing 4 scatter symbols will produce a completely different bonus game with only twister, collector and dead symbols available. You start off with 3 lives and each time a twister or collector lands, these lives are reset. Twister symbols contain a multiplier value on one of the four sides and if the value is at the top of the box, it adds to your overall multiplier. However, the grid will then rotate and if the initial multiplier isn't collected by a collector symbol, it's subtracted from the overall multiplier amount. 

Unfortunately, you will feel hard done by as you see that multiplier figure rise to great heights only to come plummeting down again as the grid rotates. Possible twister values are 1000x for the blue symbols and 10x for the pink ones. Blue twisters will require a RotoGrid symbol to make the grid turn. Pink ones perform a twist with every new spin. 

Some areas outside the UK allow for a few additional bet types with feature spins making it 5 times more likely to trigger a bonus game - these cost 3x per spin. 50x per spin will guarantee one blue oozing Beaker and one RotoGrid symbol. 75x will land you a spin that guarantees 2 blue oozing beakers and one RotoGrid symbol. 100x produces the basic free spins game and 200x takes you to the upgraded respins bonus.

These symbols can make the grid turn 90 degrees 1–4 times. Wins that were previously unavailable could come to life as they join the regular 19 paylines.

If these symbols are on the grid as it rotates, they spill to the bottom and change some symbols into wilds. Blue & pink beakers can also add multipliers up to 100x.

3 scatters award 10 free spins with an added bonus coming to the grid. You get a better chance of seeing the RotoGrid spring into action and more beakers.

The Twist of the Twisted

4 scatters take you to this upgraded respin bonus game with Twister symbols and Collect symbols joining the action. Collector symbols drag in the value of other symbols and Twisters turn the grid and add multipliers.

Win Potential

This twisted grid is highly volatile and that could be great news for some lucky players as there's 15,000x at stake. Sporadic, big wins could come your way thanks to those wild symbols and 2 bonus games. The RTP is very reasonable at 96.30%

I managed to pick up some decent payouts during the base game with 12x being the best I hit, but wins like this did land fairly frequently. Moving into the respins, over 200x was my prize. It is a frustrating bonus game, though, as those multipliers build up your hopes and then dash them again within seconds.

Design

It's quirky and silly, as you would expect with a game that goes by this name. It's all about a cranky professor called Mr Melcher and his helper Pat the rat. Smooth and colourful is the best way to describe it and the shapes help the grid set nicely into the industrial background as well. It's a good-looking creation for both desktop and mobile users to enjoy.

Our Verdict

There's a good dose of action heading your way throughout the base game as the grid rotates and makes your head spin just a little bit! It all helps to bring wins when you least expect them and those beakers can pour wild powers as everything starts to turn. The bonus games weren't my favourite part of the production and this bodes well for UK players as there's no direct buy-in in this area. You might not be in awe of Twisted Lab RotoGrid, but you'll certainly be intrigued for a while.
