3dice "japan/chinese slot" is terrible. You try hit ying yang scatters and when you get all pieces for picture you get only few spins and low multiplayer (other slots you get much better freespins even one spin).
Oh gawd, ChingChing. It's a damn pretty game, but I certainly wouldn't touch it in real play. I guess there's a market for that kind of game, but it doesn't appeal to me one bit.
But, honestly, I'd rather play ChingChing than that god awful Slotronomicon. The fact that people actually win on that thing astounds me.
