The logo 'Kung Fu Monkey' is the Wild symbol, 5 of which pays 2500x the line bet, is a dumb Wild symbol, and only substitute for other symbols except for the 2 Scatter symbols. 2 Scatter symbols? Yep, Microgaming likes to have 2 or more of everything. The Chinatown Scatter symbol appears only on reels 2, 3 and 4, and getting these 3 symbols pay 1x the total bet and triggers the Kung Fu Bonus game. The Dong Scatter symbol appears only on reels 1 and 5, and getting these 2 symbols pay 1x the total bet and triggers 10 free spins, which can be retriggered, and with all wins doubled. All other symbols pay from 1000x the line bet to 20x the line bet, for 5 of each kind. Hmm, a low paytable yet again.
In the Kung Fu Bonus game, there are 3 levels to complete. In levels 1 and 2, there are 6 opponents, 5 of which can be defeated, the other 1 cannot be defeated, but it awards either 5 or 8 free spins, depending on either level 1 or level 2 the fight took place. Get to level 3 and you face the Big Boss himself, that not-so-mighty oversized gorilla. Looks big and furious, but is actually like a punching bag. Defeating him is easy, but no need to brag. Winning all levels award a 56x the total bet prize, a 40x win coming from defeating the gorilla boss himself. But get the Free Spins award and the Bonus game ends, at either level 1 or level 2.
Kung Fu Monkey may look exciting to play, which it really can be, but the very low paytable results in poor payouts, and the free spins tend to be useless most of the time. This isn't a high variance game, so such poor payouts and its poor performance are indeed a big letdown.
