Big and small is a well known casino game all over the world. It is especially popular and widely played in Asia.
Big and small is also known as Sic bo (骰寶), tai sai (大細), dai siu (大小), or hi-lo.

It is basically a game which uses three dices, and the objective of the game is to predict the outcome of the sum of three dices.
You can choose to bet on one or more numbers, or you can just bet on either SMALL (which covers from 4 to 10), or BIG (which covers from 11 to 17). Other options are EVEN (4, 6, 8, 10, 12, 14, 16) or ODD (5, 7, 9, 11, 13, 15, 17), or TRIPLE, which is any combinations of three dices of the same kind.

If you're new to the game, this is where you can start to prepare yourself for the real game!

*****************
Because the game is played widely around the world, the rules vary in different countries. In this application, the rule is NOT based upon one specific country's rule, but is rather arranged and simplified for a better and smooth game play and handiness. The actual game in casinos are quite more complex in a way that you can bet more specifically, but the basic game play is the same.
