4-Digits (abbreviation: 4-D) is a lottery in 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.
Magnum 4D is the 1st legalized 4D Operator licensed by the Malaysian Government to operate 4D. Soon thereafter, other lottery operators followed suit, as this is a very popular game in Malaysia and Singapore. 6063 Singapore Pools is the sole provider of gambling games in Singapore. 4-D and lottery 6/45 are two of the most popular. A similar 4-D game with its prize structure fully revealed can be found in Taiwan.
4-Digits is somewhat similar to "Pick 4" in the United States and Canada
The 4-D game is believed to have originated in Kedah in 1951, based on evidence during a gambling trial in a Singapore court in 1956.
A schoolboy decided to raffle his bicycle for 100 $1 tickets, each bearing two digits. The winner would be the one whose ticket number matched the last two digits of the first prize ticket in a Malaysian Turf Club sweepstake. This led to the 2-D lottery, which in turn gave rise to 3-D and later, 4-D, betting games which were wildly popular in Singapore and Malaysia from the 1950s.
The Singapore Turf Club was the first to introduce the 4-D draw in Singapore in May 1966, offering a S$2,000 first prize for a $1 ticket. It stopped offering it in May 2004 when its sister company Singapore Pools took over all the draws.
