The Wild Machine Theme/Symbols

The imagery in The Wild Machine slot game is done comic book style and works very well. With the mad prof’s lab in the background, the reels feature playing card suit symbols as well as keys, instruments and equipment. The bearded scientist is the top symbol. Land 3, 4, 5 or 7 on a payline to win 1.25, 5, 25 or 175 x your total stake. The same amounts are also on offer from the wild.

Shape Shifting game grid

How do you land 7 across a payline then? The action starts on a 5x5 grid. On any spin you could see the reels shift into a 1x3x5x7x5x3x1 formation. This means you can create 7-symbol winning combinations. When the reels shift to the 7-reel set up, reels 1, 4 and 7 will be totally wild. The number of paylines is 40 regardless of the setup of the reels.

Wonder Wheel feature

Land the scatter symbol on reels 2, 3 and 4 on the 5x5 grid and you’ll trigger the Wonder Wheel feature – you’ll then get a spin of the Wonder Wheel. This is made up of 30 segments. 25 of those segments will award an instant cash prize. There are also 5 free spins segments. If the pointer lands in one of the 5, you’ll have the pick of 2 free spin rounds.

Gold Foundry Free Spins feature

Choose the Gold Foundry Free Spins feature and you’ll receive 8 free spins on the 5x5 grid. Between 2 and 5 reels will be totally wild on each of these free spins.

Diamond Forge Free Spins feature

Opt for the Diamond Forge Free Spins feature and you’ll play 5 free spins on the 1x3x5x7x5x3x1 reels. Reels 1, 4 and 7 are wild throughout. Any wild that lands during these free spins turns sticky and locks in position for any free spins you have remaining.

The Wild Machine slot thoughts

We enjoyed The Wild Machine. The visuals are excellent, backed by a cracking soundtrack which fits the theme perfectly. The shape-shifting game engine spices up the base game and the wild extras from the free spins can be well worth landing.

With an RTP of 96.52%, the variance is extremely high here - it can be a tricky business finding those free spins though. The max win per spin or free spin is 7,000 x stake – this can be done in the base game and on any free spin. The most likely way of achieving this is in the Gold Foundry Free Spins feature as up to 5 reels can become fully wild on every free spin.

If you’re looking for some high variance action, then a spin on The Wild Machine is worth considering. If you’re looking for big wins, Aztec Bonanza (also by Pragmatic Play) can pay out up to 19,000 x stake on every spin.
