Wild Wild West: The Great Train Heist™ is a 5 reel, 3 row, 10 fixed payline video slot with free spins, four wild features and a bonus round. It is a HTML5 video slot, keeping Netent's high standard of graphics and animations. The background is desert style and features a passing train, which fittingly includes a six-shooter barrel as the spin button. The bet level, coin value and auto-spin setting is clear and concise, although NetEnt has opted for fixed paylines.

Low paying symbols are commonly known card symbols such as clubs, hearts, spades and diamonds, while high paying symbols are the four rogues and the wild symbol. Scatters are big yellow 7s that appear on all reels, and bonus symbols are safes that land only on reels 1, 3 and 5. Pretty simple and straightforward.

Free Spins Bonus round

Since the maximum payout for this slot is only 50x bet, it needs the help of the free spins bonus round to increase the potential for super mega wins. As the wild selection for the free spins is an expanding wild, this is also the only chance to reach the maximum payout for this slot, which is a relatively modest 500x stake. Not particularly high, but regularly achievable.

When 3, 4 or 5 scatters land anywhere on the screen, the bonus round is triggered, awarding 10, 20 or 30 free spins with unlimited retriggers. The wild selection wheel appears first with four possible wild features for the free spins. These are Regular Wild, Expanding Wild, X2 Multiplier Wild, Spreading Wild. After you click stop, the wheel randomly stops on one of the features, which will be active throughout the Free Spins.

Additionally, during Free Spins, a Overlay Wild symbol will randomly appear on reels 1 - 3 in each spin and works just like the active Wild feature. This gives the slot the highest potential when the selector result is the Expanding Wild and you hit multiple Wilds on the front reels. Having a wild on all the reels would lead to the highest payout on this slot, which is a total of 10x 5OAK wilds on a 50x bet, which is the equivalent of 500x bet.

Pick and Click Bonus Feature

The feature is the less desirable bonus on this slot, as the possible payout is only between 5x - 50x bet. Not outstandingly high, but OK to keep you hooked. Hitting the three safe symbols on reels 1, 3 and 5 will activate the bonus and you only have to select once to get the win. As a check, the other two numbers are displayed after the selection, which can either be annoyance because the lowest number was selected, or a sigh of relief because you chose the highest prize.

Conclusion

Although the game seems to be very entertaining and graphically well done, we don't think it will bring in big wins on a regular basis. On top of that, the highest single line win is only 50x bet, a far cry from similar 10 line games like Book of Ra / Book of Dead with 500x bet. But these are very high variance games and sure balance killers if they don't work, whereas Wild Wild West: The Great Train Heist™ has more of a low to medium variance, giving the player less potential for big wins but longer lasting entertainment.
