The wild symbol in this game is the Chinese coin and the scatter is the tiger. I have to say that it is a bit difficult to trigger the free spins though.I have realized that it takes quite awhile for the first time. Once you trigger them, then it becomes much easier later. It is like you break the ice and after that everything is better. You need three or more scatters to trigger the free spins round and you get 8, 16 or 24 free spins. I have never gotten more than 8 free spins. It looks like it is impossible to get 4 or 5 scatters at the same time. The payouts during the free game can vary. There are times when I was ending up the bonus with only 10 x bet win. But I remember the last time I played this game I won something like 250 x bet. I got 2 wilds on the second and the fourth reel at the same time. I could not believe it. I know that that is possible but it has never happened to me before, not with this particular game.
Another thing that is worth mentioning here is that the wild has a special function during the free spins round. The wild can land only on the second and the fourth reel. If you get a wild on the second reel all your wins are multiplied by 4, and if you get a wild on the fourth reel you get x 5 multiplier. And that is not all, if you get two wilds at the same time you get x 20 multiplier, but this does not happen that often.
