The Robot is the Wild symbol, 5 of which pays 10,000x the line bet. It substitutes for other symbols except for the Scatter symbol, but does nothing else. The Robot may not be dumb but the Wild symbol is. It doesn't double any wins, it doesn't become stacked and it doesn't expand. However, getting the Robot on reels 1 and 5 at the same time triggers The Robot Butler Feature. Pick 1 of 3 items for the Robot to find. 2 chances are given to get it right, to win up to 100x the total bet amount. If failed, a consolation prize of 4x the total bet is awarded. This feature game can also be triggered during the Free Spins game. The Tray is the Scatter symbol, 5 of which pays 100x the total bet, and getting 3 or more of them on consecutive reels left to right triggers 12 free spins. Pick 1 of the Trays to win up to 5x multiplier for the free spins. More free spins can be retriggered. As for the other symbols, they pay from 1250x to 100x the line bet for 5 of each kind. An average paytable.
Playing this Robot Butler game was quite enjoyable and hilarious at times. Many a times when I asked the Robot to fetch me a sandwich, it brings me a fish skeleton and an eaten apple. When I asked to fetch my slippers, it brings me a frog instead. Hmm. Like I'm supposed to wear a frog on my foot? Sometimes, the Robot gets it right, sometimes the Robot gets it wrong. Ah well, so much for artificial intelligence in the Robot Butler for now! Maybe the 7th generation Robot Butler would be perfect by then. Nevertheless, the prizes that I got from this feature game wasn't that good at all, from a very low 4x up to 29x my bet amount. Certainly not satisfying enough.
The Free Spins games performed slightly better, with payouts of 13x up to 67x my bet amount, and I'm wondering if bigger wins would be possible at all. It should be, going by the paytable, so it's probably just not my lucky days whenever I played this Robot Butler game.
