The key slot machine symbol in the Robot Butler online slot game is, of course, the robot butler himself. The robot butler can do anything from finding your lost keys to serving your refreshments. He can even do a little victory dance when he brings you a winning slots jackpot.

The robot butler is also a wild symbol. He can substitute for any other symbol on the online slot machine to create a winning slots combination.

And that's not all. If the Robot Butler appears on reels 1 and 5 at the same time, he triggers the Robot Butler Bonus Game. That's where you can win a slots jackpot of up to 100 times the amount of your bet.

The Robot Butler casino slots game has plenty of other outstanding features. There is the Butler's Tray scatter symbol, the Free Spins feature with a multiplier of up to 5X, and the Gamble feature where you can double or even quadruple your winnings.

The day will soon arrive when we all wonder how we possibly could have survived without a Robot Butler to take care of us. In the meantime, we can enjoy everything the Robot Butler has to offer just by playing slots online with Robot Butler and over 200 other online slot machines at All Slots Online Casino.
