The Wild Machine online slot game
The Wild Machine follows a mad professor whose invention creates wild symbols across 5x5 reels. Its free-spins bonus may feature expanding or sticky wilds, and players can choose the feature’s volatility.
Theme and Storyline
Set in a makeshift laboratory, the game follows a mad scientist whose technological breakthrough unlocks the secrets of alchemy. The professor’s wild symbols can help form winning combinations, making his help central to the feature.
Graphics, sound and animation
The Wild Machine online slot may suit players who enjoy polished animation and 3D visuals. Contemporary theme music and playful effects round out the presentation. Pragmatic Play says the mobile and desktop versions offer the same quality, with a design for smartphones, tablets, laptops and PCs.

Top Casinos to Play The Wild Machine:
Gameplay
Pragmatic Play’s The Wild Machine has 5x5 reels and 40 paylines. Reel 3 can randomly gain extra positions, while paylines running from the centre position on reel 1 through reel 5 may expand to allow 7-symbol combinations. When this feature appears, the layout becomes 1x3x5x7x5x3x1 reels, and wild symbols automatically fill the newly opened positions.
There are 12 symbols in total. Scatters appear on reels 2, 3 and 4. The wild is another key symbol: it substitutes for other symbols and shares the top combination value.
The professor is the highest-paying regular symbol. Along with the wild, it can pay 50x, 200x, 1,000x or 7,000x the ‘bet per line’ when 3, 4, 5 or 7 matching symbols land on a payline.
The other 9 symbols can pay when 3, 4, 5 or 7 appear on a payline. They include books, potions, backpacks, compasses, keys and playing cards. Winning symbols must connect from left to right across adjacent reels, starting on reel 1. A 4-symbol win must therefore span reels 1-2-3-4, while a 3-symbol win must cover reels 1-2-3.
The menu lets players adjust quick spins, mobile battery saver, desktop spacebar spinning, ambient music, bet size and sound FX, and view game history. Autoplay is also available on the main slot screen.

Bonus Features and Free Spins
Wonder Wheel: Landing 3 scatters activates the Wonder Wheel. Of its 30 spaces, some award cash prizes from 7.50 to 25.00, while others award free spins. The feature provides 1 spin, and pays the prize shown when the wheel stops.
Free Spins: The Wonder Wheel starts the free-spins round, where players can choose between 2 volatility options:
- Gold Foundry: 8 free spins, with 2 to 5 reels turning into wild reels
- Diamond Forge: 5 free spins on the 1x3x5x7x5x3x1 reel layout, with wild symbols above and below the middle reels. Wilds also appear on the left and right sides, creating the possibility of 7-symbol combinations
Bet sizes, RTP and variance
Use the /- controls on the main slot screen to set your bet. The maximum spin bet is 100.00, and the minimum is 0.20 per spin. The total is divided across 40 paylines to determine the ‘bet per line’. Coin betting and coin-value settings are available, but The Wild Machine automatically sets them based on the total spin bet.
The review gives the game an estimated RTP of 96.52%, while Pragmatic Play rates its volatility 5 out of 5. RTP is a theoretical return figure, not a promise for any individual session.
Evan Carrington’s review: Conclusion
The Wild Machine video slot offers 5x5 reels or a 1x3x5x7x5x3x1 layout with sticky wilds. The 1x3x5x7x5x3x1 layout may appear at any time in the base game and is also available as a free spins bonus option. Players can choose a free-spins mode with wild reels; the review says it guarantees 2 reels stacked with wilds, with the possibility of 5 wild reels and a stated guarantee of multiple 4- and 5-symbol combination wins. These are feature descriptions, not guaranteed outcomes, but they offer Pragmatic Play fans another way to play online slots.
