He was part of a betting scam that cost Marina Bay Sands casino about $150,000 between July and August last year.
On Friday, Bai Qipei, 25, was sentenced to five months' jail on two counts of cheating.
The deliveryman was the last of five men to be dealt with. His four accomplices - Benson Ho, 25, Toh Kaida, 29, Ang Chee Peng, 28, and Ho Boon Keat, 29 - were jailed from 14 months to 3 years.
They ran their scam on Sic Bo, a game where three dice are rolled. If all the dice show the same number, gamblers can win up to 180 times their bet.
The con: An accomplice would claim to have placed a $25 bet after a triple appeared. Then Ho, the surveillance operator, would be called to check the footage. He would lie and say the bet had been placed.
