What I love about Hacksaw Gaming is that you never quite know what you are going to get. At times, their slot games can seem a bit lazy, but then you are hit with something that ticks all your boxes. Twisted Lab RotoGrid looks at every part of the ideal game: great animation, innovative ideas, and a colossal jackpot.
To get into the finer details, I play this game with my own money and relay the inner workings of Twisted Lab RotoGrid by Hacksaw Gaming. I discuss design, programming, performance of software, and what bonuses and features are present.
The official Twisted Lab RotoGrid demo is included in the review. You can access this 100% free-to-play slot with any mobile device; no download or signup is needed. If you like the game, stick with Casinos.com, which can help guide you to the best casino sites online, offering Twisted Lab RotoGrid and many more as real money casino games.
The design of Twisted Lab RotoGrid is beautiful. Using only a two-tone color scheme, we are presented with hues of purple, turquoise, and a hint of yellow. The setting is within some science lab, in which the twisted professor, Mr. Melker, and his lab rat, Pat the Rat, move each side of the slot.
The slot comes with a 5-row and 5-reel layout that carries 19 paylines. And yes, the RotoGrid is a feature that moves the entire slot clockwise. To the right of the reels are four counters for the RotoGrid feature.
The sounds used in this game are atmospheric to the setting, in which you also hear the professor humming to his thoughts.
I’m a sucker for slot games that have their aesthetics on point. As soon as I saw what Twisted Lab RotoGrid looked like, I was all over it.
When you load the game, you will see that the betting defaults to $2 per play. This is the first thing to change before you play, should this be too much or too little. Use the – and + buttons to switch the values that run between $0.10 and $100.
With your bet set, press the spin button to begin the game. Wins are formed by landing 3, 4, or 5 matching icons or symbols on any one of the 19 paylines. The payline patterns and the symbol values are found on the paytable. Select the menu button to access this and to also learn about the game rules.
The lower symbols are the feather, the leaf, the egg, and the mushroom. The medium symbols are the tentacle, eyeball, fangs, and brain. The highest rewarding symbols are the three different science beakers.
During play, special symbols will become active, and bonus rounds can be played, but the basics of the game are simple: keep on spinning until enough is enough.
The features and online slot bonuses that are present in Twisted Lab RotoGrid by Hacksaw Gaming.
RotoGrid: Land the RotoGrid symbol to activate the feature that can rotate the entire slot clockwise and help form new wins. Each symbol, which is collected on the counter to the right of the reels, moved the slot 90 degrees.
Oozing Beakers: When the game rotates, the beaker symbols will spill and break. The content will end up on the bottom row, and all symbols covered by the ooze will turn into Wild symbols. The blue beaker holds multiplier values that range from x2 to x100. The pink beaker only holds multipliers x2, x3, x4, x5, and x10
Unleash the Ooze: Land 3 FS symbols to activate the 10 free spins bonus feature. This bonus round plays with a higher chance of more RotoGrid symbols.
The Twist of the Twisted: Land 4 FS symbols to activate the round. This bonus, however, only uses Blue and Pink Twisters, RotoGrid, and Collect symbols are in use, as well as non-paying symbols [fish skeleton, cat skull, apple, bird skull]. The Blue Twister comes with 4 multiplier values. The top one is the one in play until the grid rotates. The Pink Twister symbol carries multipliers ranging from x1 to x1000. Blues rotate with the RotoGrid, and Pinks rotate with each spin played. The Collector symbol gathers all multiplier values of Blue and Pink Twisters. This bonus comes with 3 refill lives that reset when the Collector symbol drops.
Buy Bonus: Buy your way into bonus rounds or improve your chances by increasing the rate of features. Twist of the Twisted will cost you 200x your bet amount. Unleash the Ooze is 100x your bet, and the Oozing RotoGrid Feature will cost 75x your bet value.
I’m a sucker for slot games that have their aesthetics on point. As soon as I saw what Twisted Lab RotoGrid looked like, I was all over it. I loaded the game up, set my bet per spin to $2, and selected 50 auto-spins.
On the second spin, I landed one RotoGrid, which activates the rat to pull a lever and spin the slot. After this, small sums were won, but after 25 spins had been played, I hadn’t won enough to be enthused by the game. In fact, as each spin played, less was happening. The odd win that was lower than my $2 bet would come up. I landed the RotoGrid symbol again, but nothing came of it.
My last 25 spins were over in a flash, and the whole thing turned out to be one of the worst experiences so far this year. What a shame.
The max payout is 15,000 times the value of the player's bet. If you cash in at $100 per spin, then you can win a jackpot of $1,500,000! The volatility is at a high setting, which is why my gaming sucked, and the RTP comes in at 96.30%.
This game is all about look and little substance. I think the volatility kills this game and ruins a game with a lot of potential. Given the theme, I wanted a bit more than a rotating slot. It’s not entirely new, but it’s nice to see a game being different.
If you like the theme of this slot or how it played, then I recommend you check these casino games next time you’re online:
Rogue Rats of Nitropolis by ELK Studios
Dr Watts Up by Games Global
Sparks of Genius by Play’n GO
