Underground Tuning Slot Review

How to play

Underground Tuning Slot uses a traditional video slot layout and has five reels with each reel having three rows. The game also uses 20 paylines that are fixed and always in play. You can hover your mouse over the payline numbers at the side to check out the potential different winning combinations.

For your bet value, you can change two features - the coin value, and the number of coins. You can change the coin value from a minimum of 0.01, to a maximum of 1. Also, you can change the number of coins from a minimum of 1 to a maximum of 5. As a result, the minimum bet value is €0.20, and the maximum is €100. This means the game is suitable for both high rollers and low spenders.

There is also an autoplay feature. Simply click on the “auto” button and you can then choose the number of spins from 10 to 500. There are, however, no advanced features for the autoplay mode. You can also click the max bet button to quickly set your wager to the maximum bet value available. 

Symbols and payouts

Underground Tuning has a small paytable with just eight symbols. It also has a few special symbols. For gameplay, it has 20 paylines. The basic symbols are Q, K, A, a speaker, an exhaust, a wheel, a brake disk, and a gear stick. 

The graphics of the different symbols look fantastic and the various car parts look awesome. Of these symbols, the letters are the lowest paying. The Queen, King, and Ace all have the same lowest payout of 10x the line bet for three symbols. They also all have the same maximum payout of 75x the line bet for five symbols.

Of the higher-paying symbols, the gear stick gives the highest multiplier in the game. If you get five of this symbol, you get a superb payout of 3,000x the bet per line! The brake disk comes in next and has a payout of 1,500x the line bet for five symbols.

There is also a wild symbol which is a tank of nitro used to super-power the racing cars! This wild symbol can land randomly anywhere on the reels and substitutes for all other symbols, except the free spin symbol. This symbol can also turn into an expanding wild symbol randomly in the free spin bonus rounds.   

Best Underground Tuning bonus feature

The Underground Tuning bonus feature is a free spin bonus round. The Underground Tuning free spins are triggered by the free spin bonus symbol (a green-haired lady). If you get three free spin symbols, you earn 10 free spins.

During these free spins, the basic paytable is used. Also, the bet value and coin value used to trigger the free spins are used for the bonus rounds. There is one difference, however. During these bonus rounds, there is a Nitro Wild symbol. This will appear as an overall stacked wild symbol on any reel and greatly increase your chances of winning.

You can also trigger additional free spins by getting more free spin symbols during the bonus rounds. This can potentially lead to some large winning combinations and a high number of free spins.

The Underground Tuning Return To Player is a brilliant 97.01%. This is currently above the industry average for video slots which is between 95-96%. In terms of volatility, Charismatic has not currently given this video slot any volatility rating. However, the biggest wins will come from the free spin bonus rounds.
