Singapore Pools started selling 4D bets in May 1986 on newly introduced computerised gaming systems. This move to utilise technology in our operations was a key milestone in our company history.
In April 1993, the 4D draw was tied to the Singapore Sweep draw, as it still is today. Every first Wednesday of the month, 4D Winning Numbers are reflected as last four digits of the top 23 winning number combinations of the Singapore Sweep draw.
Regular 4D draws take place every Wednesday, Saturday and Sunday.
Chances of your 4D number combination winning a prize differ, depending on your chosen bet type.
