Theme

8.5 

We are not historians, but we know well that the culture of China is inextricably linked with masks. And now some facts from Google: In China, masks appeared long before the beginning of our era, during the reign of the Zhou and Shang dynasties, so the mask has a high value in Chinese culture. During the rituals, Chinese shamans had to wear a mask, because only with them they could communicate with deities.

The provider was clearly inspired by this when creating this slot, since 5 prize symbols appear on its playing field, and all of them are shamans, whose faces are hidden under beautiful, but a little frightening masks. For the low-paying symbols, he used stylized suits of playing cards that thankfully don't look like they were taken from another world.

During the gameplay, pay attention to the fans, as these are Bonus symbols that land on reels 1, 2 and 3 to trigger the free spins feature. From time to time you may see "Mask Reel" - these are special symbols that land on reels 3, 4 and 5 to activate the corresponding feature. There are also Wilds (Chinese hieroglyphs) and these symbols only land on reels 2, 3 and 5.

Overall Rating

8.3

The audiovisual performance of Winning Mask I is weak and JDB should work on it a bit to get more players into their games, but we love the unique theme of ancient Chinese masks. The gameplay is fast and filled with a bunch of special symbols and we liked the free spins feature that allows you to get up to 150 extra free spins and win up to 5,500x the bet using mask symbols that are converted into a premium symbol. Since everything is fine with the mathematical model of the game, we can advise it to all high-risk players.
