The Wild-O-Tron slot machine from NetEnt invites you to get ready for a thrilling sci-fi adventure revolving around all kinds of robots including Transformers, Power Rangers and Wall-E. The visually-stunning release will take you to a futuristic factory ruled by cyborgs. The 5-reel, 20-payline game can help you grab some massive riches by transforming one to six robot icons into Wild symbols during the Wild-O-Tron feature that you can activate at random at the start of each spin. The top prize on offer is 500 coins.

Before you embark on a journey to the sci-wi universe, make sure to adjust your bet by clicking on Level +/- and Coin Value +/-. If you are a high-roller, press Max Bet that will automatically select the highest wager which is 200 coins. In case you get tired of spinning the reels manually, click on the Autoplay option that will spin the reels without interruption for up to 1,000 times. Spin will set the reels in motion once you have chosen the bet range.

Speaking of graphics, Wild-O-Tron 3000 resembles 1960s sci-fi movie scene with the reels set in a cyborg lab with an electric machine placed to the right of the grid. In our opinion, the whole arrangement simulates the combination of Dr Who and Transformers, so if you enjoyed these, you are sure to be in for a treat. The main symbols include the red robot, orange robot, yellow robot, blue robot, green robot, metal robot and the copper robot. Wild is the metal Orb, which substitutes for all other icons to complete a winning.

The NetEnt title features only one bonus feature. It is the Wild-O-Tron feature that can randomly be triggered before each spin. Here, anywhere between one and six robot symbols can turn into Wilds, and, if you are fortunate enough to see the entire grid filled up with Wild icons, you will win the Jackpot of 500x your wager.

Wild-O-Tron 3000 is a low-to-medium-variance video slot with an average return to player of 96.01%. We must admit that we expected more from the game and we are disappointed that the only bonus on offer is the Wild-O-Tron feature that is sometimes hard to activate. That being said, if you enjoy action-packed titles with an array of extras, you may want to skip this one. The maximum potential win up for grabs is 100,000 coins.
