Silicon, the maker of Valleys, and not to be mixed up with Silicone, the maker of false female anatomy.
With this highly pointless introduction, I present the slot Silicon Spinners by AvatarUX and Mr. Wu.
Who’s Wu, you say? Wu is the one who helped make this game, but it’s not all down to Wu, you know. It’s down to who you know, and Wu knows AvatarUX, the big company behind Silicon Spinners. As it’s slightly harder to wordplay with its name, let’s just leave that there.
The Silicon Spinners slot pays homage to the Silicon tech giants that sprung out of some random valley in North California. Of course, the developer does this using caricatures so it doesn’t get sued for image rights.
The content of this review includes features and bonuses, settings, and performance. As a reward for reading this review, you can play the free demo of Silicon Spinners. What’s the catch? Simply make a free account with Casinos.com and you can immediately access the slot, along with many others.
To play Silicon Spinners, load it in an online casino of your choice and start by selecting the value of your bet. Bets range from $0.10 to $300, a price you pay per spin. The amount you pay per spin impacts the amount you win, especially given that the jackpot is 20,000x the betting value. With the bet decided, you can start the game by pressing the spin button.
The slot possesses three rows and six reels that can expand through the Zap Reel feature. This makes the game grid increase from a 3x5 grid to a potential 5x5 grid. This expansion gives the slot up to 46,656 ways to win. Take heed that the volatility of this slot is set to a high level. This means it can pose difficulty in landing regular wins but will come with higher payouts if lucky.
Wins are made by landing three to six matching symbols on the reels. These must fall across adjacent reels with no gaps. What I like about this slot is the innovative new Tumble feature by AvatarUX called the PopWins feature. With traditional Tumble features, also known as Cascading Reels or Avalanches, the slot removes winning symbols, and the symbols above drop into the vacant spaces. With the PopWins feature, winning symbols are zapped away, and new symbols enter the space without any drop-downs from other symbols. This can generate more wins.
There is more to this game, which is why I'll explore the Silicon Spinners free spins and bonus features in this section.
Reels 1 and 6 start off locked with Hot Bonus symbols. If you land a wild symbol on these reels, you unlock them for the rest of your spins. The Zap Reel also contains Zap Reel Rewards.
Silicon Spinners by AvatarUX is a peculiar game that provides enough in-play features for the base game and two bonus rounds to sustain interest. Much of it reminds me of Nolimit City slots, my favorite, so I’m happy to recommend this game to those who like a bit of the weird and odd.
