What is 4D Lottery?
4-Digits (abbreviation: 4-D) is a popular lottery game Germany, Singapore, and Malaysia. Individuals play by choosing any number from 0000 to 9999. Then, twenty-three winning numbers are drawn each time. If one of the numbers matches the one that the player has bought, a prize is won. A draw is conducted to select these winning numbers. 4-Digits is a fixed-odds game.
Singapore Pools is the sole provider of gambling games in Singapore. 4-D and lottery 6/49 are two of the most popular. Betting is illegal with any other providers.
Methods of Play
Ordinary entry refers to a specific number. Example: 1234. 4-D Roll substitutes any one of the four digits with 'R'. (i.e. R123, 1R23, 12R3 and 123R) where 'R' denotes all digits from 0 to 9. Only one digit can be substituted with 'R'. For example, if you mark R234, you are actually buying 10 Ordinary Entries (i.e. 0234, 1234, 2234, 3234... 9234). System entry is a bet on all the possible permutations of a 4-D number, for example the number 1234 has 24 permutations (1234, 2341, 3412, 4123…). iBet is a System Entry bet priced from $1, regardless of the number of permutations. Quick pick is bet on a random number selected by a computer.
In Singapore, 4-D draws are conducted every Wednesday, Saturday and Sunday at 1830h (SG/HK Time) at Singapore Pools' main branch at 210 Middle Road. Anyone above the age of 18 can attend the draws.
An independent external auditor and five draw officials are involved in the draw process. Before the draw, a specially designed computer is run to randomly select the draw machine and the set of draw balls to be used. A backup machine is also chosen.
The selected draw balls, numbered 0 to 9, are weighed to ensure that their individual weights are within an acceptable margin of error. This is to ensure that each ball has practically the same chance of being drawn.
The selected machines, secured under lock and numbered seal in a storage room, is transferred to the draw hall, along with the balls.
The balls are loaded into the draw machine in front of the audience. A member of the audience is then invited to press the start switch on the control panel, launching the draw. The balls in the draw machine, made up of four transparent cylinders, spin until a ball is sucked into a groove found in each cylinder.
The drawing process, starting from the consolation prizes, is repeated until all 23 sets of winning numbers are drawn.
