Gem fire is a strictly luck game, similar to a slot machine. There are 5 different minerals: jade, onyx, amethyst, ruby and salt.
To play, you bet anywhere from 10 kSAT to 90 kSAT (gem fire on Xiaobado @ Jan. 14/2014) which launches 5 fireworks that represent the various minerals. To win, you must get a certain combination of minerals. For instance if you get 4 rubies you win 10 times your bet (e.g. 1 BTM for a 10 kSAT bet).
The current (Jan. 14/2014) betting levels and payouts for the gem fire game on Xiaobado are shown on the right.
Because it is a luck game, there are no "tips" on how to play gem fire. You bet... you pray... and you either win or lose!
