Happy 5 is played by randomly drawing 5 balls from 20 numbered balls (01 to 20). The results are based on the combination of the 5 numbers drawn.

There are 5 bet types:

• Big/Small – The total sum of the 5 numbered balls drawn is greater than or equal to 53 (Big); smaller than or equal to 52 (Small). 

• Odd/Even – From the total sum of the 5 numbered balls drawn, the last digit is an odd or an even number. 

• More Odd/More Even – From the 5 numbered balls drawn, if more than three of these numbers are odd numbers, bets on Odds win. If more than three of these numbers are even numbers, bets on Evens win. 

• 4 Seasons – Predict the total sum of the 5 numbered balls drawn will fall in a specific range name. There are 4 different range names to bet on: 15-33 (Spring), 34-52 (Summer), 53-71 (Autumn) and 72-90 (Winter). 

• Combo – For example, a BIG/ODD bet means you predict that the total sum of the 5 numbered balls drawn is greater than 53 and the last digit from the total sum is an odd number. Other combinations you can bet on are BIG/EVEN, SMALL/ODD and SMALL/EVEN.
