Robojack slot

RoboJack slot
The robots are the main characters of the several slots from one Microgaming company alone. By the way, if you count up the slot machines of a similar theme of all providers of gambling software, then you can get a pretty good figure. But, despite such an abundance, each of the online slots about a robot's different originality, whether it's design, the bonus features or a storyline.

Robojack slot is another proof of the skill of developers who once again managed to implement the ordinary theme into an exciting decision. The percentage of the winning at the slot is 94.26%, and the maximum winning for one spin of the reels can reach 90,000 coins. You can play free at the demo mode of this slot machine without the registration on this page.

Personal testers opinion

During the game of 177 spins, one will trigger the bonus feature. You can receive up to 27% of the prize pool in them. Also, in the usual spins, the probability of falling out of any pay combination is equal to 29.79%. I would not recommend this slot for the execution of the wager requirements. But, in general, I left neutral recommendations.

Description of the slot machine

You will need to show a fantasy that understands where this time the mechanical men spin the reels. Judging by the dark colours of the design and the metal inserts – it is some sort of bunker where robots are busy making the gold coins, minting them without stopping.

In my opinion, one more advantage of this slot machine was its sound accompaniment – the musical fragments with the metallic notes here are even very handy. You should cheat the clever man-machines, and then they will build themselves into the pay combinations, paying you the maximum number of newly minted coins.

Symbols and payments

  • Even robots sometimes play cards. This is confirmed by the fact that on the reels of this slot you can see the symbols from the deck of cards, only made in the so-called mechanical style. Such designations, having formed in a pay line, can bring from 20 to 625 coins.
  • The Green symbol, Yellow Box and the Chest of Gold will deposit to the player's account for 100 – 2500 coins.
  • The robot with the dollar sign in the middle will be so pleased with your meeting that it can give you 250, 750 or 3125 coins.
  • The wild symbol is the logo of the Robojack slot. It can replace symbols to complete the successful combination, and also pay out his prizes for an amount that can reach 6250 coins.
  • The meaning of the mechanical device with the inscription Scatter is understandable but still requires an additional explanation. The appearance of 2-5 Scatters deposits in the account by 75, 225, 1500 and 7500 coins respectively. As soon as at least 3 Scatters appear on the screen, the inscription Scatter will change to Bonus, and the free spins series with the bonus features will be triggered for the lucky player.

Bonus and free spins

  • There is no separate bonus game at this slot machine. But the original designed free spins more than successfully replace it. Before the reels spin in free spins at the slot, a screen with 5 capsules appears in front of the player, each of which has a robot with certain capabilities. The choice of the first robot happens automatically, but if you are not satisfied with the set of bonus features, you can take a chance and make your choice by clicking on the capsule.
  • You can learn more about the bonus functions of each robot in the paytable. Among them, there will be a robot replacing the reel with wild symbols and the robot is adding wild symbols or paying for every appearance of the scatter. Free spins can be extended, and their number reaches up to 65 spins.
