The Wild Machine online slot game
The Wild Machine slot follows a mad professor whose invention creates wild symbols across 5x5 reels. Its free-spins bonus can feature expanding or sticky wilds, while the feature lets players choose the volatility.
Theme and storyline
Set in a makeshift laboratory, the game follows a mad scientist whose technological achievement unlocks alchemy’s secrets. The professor’s wild symbols can help connect winning combinations, making his assistance central to the feature.
Graphics, sound and animation
The Wild Machine online slot is suited to players who value polished animation and 3D visuals. Its contemporary theme music and playful effects support the presentation. Pragmatic Play states that mobile and desktop versions receive the same quality, with the design covering smartphone, tablet, laptop and PC casino play.
Top Casinos to Play The Wild Machine:
Gameplay
Pragmatic Play’s Wild Machine offers 5x5 reels and 40 pay lines. Reel 3 can randomly gain extra positions, while pay lines running from the centre position on reel 1 through reel 5 may expand to accommodate 7-symbol combinations. When that feature appears, the layout becomes 1x3x5x7x5x3x1 reels, and the newly opened positions are automatically filled with wild symbols.
The reels contain 12 symbols in total. The scatter appears on reels 2, 3, and 4. The wild is another key symbol: it acts as a substitute and shares the top combination value.
The professor is the strongest-paying regular symbol. Alongside the wild, it can award 50x, 200x, 1,000x, or 7,000x the ‘bet per line’ when 3, 4, 5, or 7 matching symbols land across a pay line.
The other 9 symbols can pay when 3, 4, 5, or 7 appear on a pay line. These regular symbols include books, potions, backpacks, compasses, keys and playing cards. Winning symbols must connect from left to right across adjacent reels, beginning on reel 1. Thus, a 4-symbol result qualifies only across reels 1-2-3-4, while a 3-symbol result must span reels 1-2-3.
The menu lets players set quick spins, mobile battery saver, desktop spacebar spinning, ambient music, bet size and sound FX, as well as view game history. An autoplay setting is also available on the main slot screen.
Bonus features and free spins
Wonder Wheel: Landing 3 scatters activates the Wonder Wheel. Its 30 positions include cash prizes from 7.50 to 25.00 and spaces that award free spins. The feature gives 1 spin, and the prize indicated when the wheel stops is paid.
Free Spins: The Wonder Wheel starts the free-spins round. Players get 2 volatility choices for that feature:
- Gold Foundry: 8 free spins, with 2 to 5 reels becoming wild reels
- Diamond Forge: 5 free spins use the 1x3x5x7x5x3x1 reel layout, with wild symbols above and below the middle reels. Wilds also appear on the left and right sides, creating the chance for 7-symbol combinations
Bet sizes, RTP and variance
Use the /- controls on the main slot screen to set the bet range. The maximum spin bet is 100.00, and the minimum is 0.20 per spin. That total is divided across 40 pay lines to determine the ‘bet per line’. Coin betting and coin-value settings are available, although ‘The Wild Machine’ slot automatically sets them from the total spin bet.
According to the review, bets have an estimated 96.52% RTP, while Pragmatic Play assigns the slot a 5 out 5 volatility rating. RTP is a theoretical return figure rather than a promise for any individual session.
Conclusion from Evan Carrington’s review
The Wild Machine video slot is described as offering 5x5 reels or the 1x3x5x7x5x3x1 layout with sticky wilds. That 1x3x5x7x5x3x1 layout may appear at any point in the base game and is also offered as a free spins bonus option. Players may choose a free-spins mode with wild reels; the review says it guarantees 2 reels stacked with wilds, alongside the possibility of 5 wild reels and a claimed guarantee of multiple 4- and 5-symbol combination wins. These feature descriptions concern the game setup, not a guaranteed result, but they give Pragmatic Play fans another way to play online slots.
