Singapore registered their first point at the Asian Games men's football tournament when they drew Oman 3-3 on Wednesday in their second Group C match.
With Palestine beating Tajikistan 2-1 earlier, Aide Iskandar's team needed to avoid defeat at the Hwaseong Sports Complex Main Stadium to stay in the competition.
Sloppy defending saw the team go 0-1 and then 1-3 down to goals from Hatem Hamhami, Rashadi Shakili, and Saud Farsi, with Sahil Suhaimi and Faris Ramli scoring for Singapore to end the first half on a 2-3 deficit.
But Aide Iskandar's men rallied after half-time, and equalised through a Safuwan Baharudin header five minutes from time.
They play group leaders Palestine, who have qualified for the last 16, on Sunday, and need a win to stand a chance of going through.
