With the current rise of robotic technology, Microgaming's 2014 Robo Jack slot release is more topical than ever! This game doesn't have a human being in sight – it's a fun take on AI robots (led by the brilliant if a little geeky Robo Jack) who present you with 243 ways to win rewards over five electric reels. In addition to standard base game winning symbols, the key feature of Robo Jack is the innovative and varied free spin robot, where rewards are extensive. So, before the rise of the machines happens for real, our slot review will thoroughly prepare you for the virtual one. Read on for Robo Jacks' key features, payouts and bonuses.

The leader of the robo squad is, unsurprisingly, Robo Jack. (Are we alone in having the impression he could be the love child of Starwars' RTD2?) The gamescape is a grey industrial complex, but the robots and slot symbols are far from bland, featuring a neon matrix of Robo Jack, treasure, robot power boxes, nuclear kits, colorful letters, and five of Jack's metallic friends. In addition to Robo Jack wilds and standard base game paying symbols, the big player in the video slot is the dollar scatter symbol, which is integral to bringing the free spin robots out to play. The game has a reasonable 96.25% return-to-gamer level.

Robojack has a huge 243 ways to win, with a vast array of winning combo's and bonus rewards. The game can be played from low to high stakes, with a max jackpot of 90,000 for high rollers. The dollar scatter logo pays out a huge 21000x if you manage to spin five symbols on a payline, while other icons pay a variety of prizes for matching two to five symbols.

Matching three dollar sign bonus symbols triggers the interactive free spin bonus. This takes you into Robo Jack's lab facility, where five robots lie ready to be released from their storage tubes. Your challenge is to pick a number to select a valuable bot, but you can gamble and guess again if you're not happy. Your friendly robot comes complete with free spin rewards and slot machine bonus power:

• Orange robot awards a max of 60 free spins with extra wilds
• Purple robot awards up to 40 free spins with scatter prizes
• Green awards a maximum of 40 free spins with a wild reel
• Pink robot awards up to 65 free spins with x2 scatter re-triggers
• Green X3 robot awards a max of 50 free spins with a 3x multiplier
