I could tell from the looks of the graphics and icons used that it may be from the same game provider of 300 Shields. The game isn't a new one, so I cannot really complain much on its lower quality of presentation. The Emperor is the Wild symbol, you know who that is, appearing only on reels 2, 3 and 4, substituting for other symbols except for the Scatter symbol, but doesn't do anything else. No payout, no doubling of wins, no stacking and no expanding. All it does during the free spins is to give either a 'thumbs up' for more free spins, or a 'thumbs down' for nothing at all. I wish he could be more smarter than that!
The Shield is the Scatter symbol, paying 100x the total bet for getting 5 of them, and getting 3 or more of these Scatters trigger 10 free spins with all wins doubled. A 'thumbs up' from the Emperor randomly adds 1, 2 or 3 more free spins, but a 'thumbs down' gets nothing. Sheesh! The Emperor should have given at least 1 more free spin for each appearance, to cover back for not doubling any wins and for no-retriggering of the Free Spins game. As for the other symbols, the Queen pays 5000x, the Tiger (a tiger in a Roman country?) pays 2000x, and the rest pay from 200x to 100x, all per line bet for getting 5 of each kind. An average paytable.
