Spin-Vention Review

Spin-Vention is a video slot with 5 reels, 4 rows on each and 20 fixed pay-lines. This retro at the same time futuristic game has high volatility and a standard return to player of 96.00%. You can play it with wagers from 0.20 to 100 credits. There are 5 reels and an extra horizontal reel where only special symbols land. They trigger the features, bonuses and modifiers in the game. You can win up to 10,174 times your stake per spin.

In the base game, you can activate the Prize Line feature, which includes 7 special symbols. The gold coins symbol is a bet multiplier special one. The two pink arrow symbols will transform symbols into wilds. The green one functions as a bet multiplier. The turquoise globe symbol, on its side, triggers the Pick Bonus. Apart from this bonus, there is a Free Spins game you can activate. During the Pick Bonus, you will win from 2 other special symbols.

The Design

Spin-Vention is a retro-themed and aimed at the future steampunk slot. It offers a lot of gadgets, fluorescent electrical lights and inventions. The game is set onboard a flying ship with clouds seen drifting behind the reels. The playing setup is made to represent an automatic cash creating machine.

There are 5 reels and a top row above them with 5 symbols over them. These are flanked by electric lights from electricity running through the machine. On the reels, you will see 3 characters – a robot, a lady scientist and the main inventor Sir Lucien Callan.

There are clock detonators, cube and standard wilds, gears and other gadgets. The melody that plays during the rounds is melodic. It creates a mysterious atmosphere and merges you into the adventure. The top reel that spins horizontally can contain various special symbols. These are modifiers and trigger extra features. The images of the symbols are colourful, bright and unique.

Spin-Vention Gameplay

Spin-Vention has 6 standard symbols, 1 standard wild and 9 special symbols. To get wins you need 3 to 5 of a kind symbols on a pay-line landed left to right and starting from reel 1.

The light bulb, gear and other gadgets have the lowest value of all. These pay equally – 0.10, 0.25 and 0.50x bet for 3, 4 and 5 matching symbols on a line. The premiums are the robot invention, the lady scientist and Sir Lucien Callan. The lady explorer and the robot pay 0.50, 1 and 2.50x bet for 3, 4 and 5. The most rewarding of all symbols is that of Sir Lucien Callan. It grants wins of 0.75, 1.50 and 4 times the stake for 3, 4 and 5 on a line.

The standard wild symbol has the word itself and ensures wins of 1, 2 and 10 times your stake for 3, 4 and 5 on a line. It substitutes for all except for the special symbols. The latter are 7 in the base game and 2 more during the Pick Bonus. The cube symbol is a second wild. It substitutes for the standard symbols and wild but not for the other special ones.

Spin-Vention Features / Bonuses

Spin-Vention includes plenty of features in the base game, free spins and bonus games. One of them is the Prize Line feature, which is active in the base game, during the Pick Bonus and free spins. Above the reels, you can see an extra row, on which land only special feature symbols.

At the beginning of each spin, the leftmost special feature symbol and any others from the previous bet disappear from the grid. The rest of these special symbols shift left and fill the empty spaces on the extra horizontal reel. New special symbols appear from the right until all 5 positions on the top row get filled.

Six special feature symbols can land above the reels. They include the blue globe and the two pink wild-labelled symbols. Among them, there is a symbol with gold coins and a number. It gives you credits equal to its displayed value, which ranges between 2 and 100 times your bet.

The pink symbol with the bottom-pointing arrow and the word ‘WILD’ on it transforms all the symbols on the reels below it into standard wilds. There is a similar pink symbol with the word ‘WILD’ and two crossing arrows. It transforms random symbols on the grid into standard wilds. Their number is equal to the number written on that symbol, which can range from 3 to 20.

This means that between 3 and 20 symbols can turn into wilds on a spin from that symbol modifier. These two special symbols give you more wilds. This results in potentially more and better winning combinations. After all, the wild is the best paying of the symbols in the game.

The green special symbol multiplies all your awarded credits on the current bet by the amount displayed on that symbol. It can have a value of x2, x3, x4, x5, or x10. You can have more than 1 green special symbols appear on the extra top reel. In such a case, their amounts are multiplied by each other and increase your wins. The green symbol multiplies the wins from the Free Spins Bonus and the Pick Bonus after these rounds are completed.

The turquoise globe special symbol activates the Pick Bonus. It gives you a random number of lives that are equal to the number displayed on it. In case you have more than 1 globe special symbols on the same spin, the Pick Bonus will play more times sequentially.

The globe with the turquoise special arrow symbol gives you the free games bonus. The free spins number you will receive is the same as the number on that symbol. In case you land more than 1 of this scatter, you will win a total of all free spins displayed on all of these symbols.

The bright yellow-orange cube special symbol can appear in all reel positions. It gives you the respective special feature above that reel. If you have at least 1 cube symbol on any position, there is a chance that 1 or 2 more cube special symbols will land on other reels. This happens before the special features are activated. You can be so lucky as to get a maximum of 1 cube special symbol per reel.

Your wins will be paid out after all standard wild symbols have appeared from the landing of the two pink transforming symbols. On your first bet at the start of the spinning sequence, all 5 positions above the 5 reels will be filled with gold coin symbols only. Each of them will have a value of 2, which pays 2x the total bet.

Spin-Vention has a Free Games Bonus. You trigger it with 1 or more globes with a turquoise arrow special symbols landed above cube special symbols. The free spins number you will recieve is the total from all globe with turquoise arrow symbols. The free spins play with the same base game symbols having the same payouts. The special symbols on the top horizontal reel are also the same as in the base game.

There is a standard wild with the word on it and a special cube wild. Two transformation wild symbols and 3 special ones are also present in the game. The free spins play automatically at the same line bet that triggered them. During them, the same Prize Line feature with the same 7 special feature triggering symbols as in the base game are active. The free games end once you run out of them or you have won and played 100 free rounds.

Besides Free Games and the Prize Line feature with 7 modifying symbols, Spin-Vention offers a Pick Bonus. You can activate it in the base game by landing a turquoise globe symbol on any cube special symbol on the same spin. It starts with an x1 pick bonus multiplier and as many lives as the value of the triggering globe symbols. In this bonus, you will play with 2 more special symbols: a gear and one that looks like a detonator in red and grey.

Choose the gear symbol, which can reveal a credit price of between 1 and 10 times your total stake. Each of your picks will reward you an amount equal to the value of the gear multiplied by the current pick bonus multiplier. The latter’s value increments by 1 after every 7 picks. Choosing a gear symbol may also reveal a detonator symbol. Each of these symbols reduces the number of pick bonus lives by 1, so you don’t really want to get it. When your pick bonus lives reach 0, the Pick Bonus ends.

The Conclusion

Spin-Vention is unique in many aspects and has an unusual theme and modifiers. There is a feature with 7 different modifying special symbols. With their help, you can trigger the free spins and the Pick bonus. Visually and in terms of soundtrack, the slot is impressive too.

You will spend a great time with it and can win a total of up to £ 1,017,400 on each spin. It may take you a while to get used to the game rules and modifiers, which are numerous and not easy to grasp at first. Still, the time and effort are worth it since the features and game mechanic are unique.
