Microgaming takes up the popular space-aged sci-fi theme and puts its own spin on it with Robo Jack, a five-reel three-line online video slot. The high-tech setting of Robo Jack slot appears to be the inside of some robotics mastermind’s secret laboratory; with metallic grey walls and a collection of robotics-related items including nuts, bolts, jumper cables, and even particle generators.
In addition to being a visually engaging slot, Robo Jack offers plenty of auditory entertainment, with every animation accompanied by metal clangs, electronic beeps and buzzes, and other sounds one would expect to hear in a workshop where artificial intelligence is created.
Coin Values and the Betting Range
Robo Jack operates according to the 243-ways-to-win system, which is considered by many slots aficionados to be a far more lucrative system since combinations do not have to appear on active paylines in order to win.
Players may wager between one and 10 coins per spin, with Robo Jack coin values ranging from 0.01 to 0.25. This means that players can make Robo Jack as safe – or as risky – as they like.
The Wild Robo Jack Logo
The wild symbol in Robo Jack is quite easy to spot as it takes the form of the Robo Jack logo. It is the most directly valuable symbol in the entire game because five of these in a row pay out the Robo Jack base game jackpot of 90 000 coins.
Additionally, as per usual, the Robo Jack wild is special because, like the joker in some card games at iPad casinos, it can stand in the place of any other symbol to complete winning combinations. The only symbol that the wild cannot replace is the scatter.
Free Spins from the Scatter Symbol
Although the Robo Jack logo is the game’s most valuable symbol, it does not yield the highest possible wins. It may sound paradoxical but it is true. Although it does not pay out very much itself, the symbol that opens the door to the biggest Robo Jack wins is the scatter, which takes the form of a dollar sign stamped on the door of a vault. That’s because, when three or more scatter symbols appear on the Robo Jack reels, the game’s free spins bonus round is triggered… And that’s where the real money is won.
The Robo Jack scatter works a little differently from the norm in that the free spins are not unlocked immediately. Instead, a large metal door slams shut over the reels and five robots, each a different colour with different features, appear…
Five Rainbow-Coloured Bonus Robots
This is not a standard pick-em bonus feature so players do not get to select their own robot – one is selected for them at random. However, if they are not happy with the selection, they may ask for a second robot to be selected for them. Unfortunately, though, they can only do this once and they cannot go back on their choice so there is some risk involved. Here is what each of the five Robo Jack robots has to offer:
- Dark Green: 3x multiplier on all wins and 10-50 free spins, depending on the number of scatters landed.
- Orange: Extra wild symbol and 12-60 free spins.
- Purple: Random scatter prizes with up to 10x multiplier and 40 free spins.
- Pink: Possible re-triggers of free spins with just two scatter symbols plus up to 65 free spins.
- Light Green: One completely wild reel per free spin and 4-20 free spins.
