Sky fire is a strictly luck game, similar to a slot machine. There are 8 different sky elements: tornado, cyclone, sandstorm, hail, lightning, snow, rain, and sun.
To play, you bet anywhere from 1 BTM to 9 BTM (sky fire on Zhifu @ Jan. 14/2014) which launches 5 fireworks that represent the various sky elements. To win, you must get a certain combination of elements. For instance if you get 4 hail you win 33 times your bet (e.g. 33 BTM for a 1 BTM bet).
The current (Jan. 14/2014) betting levels and payouts for the sky fire game on Zhifu are shown on the right.
Because it is a luck game, there are no "tips" on how to play sky fire. You bet... you pray... and you either win or lose!
