Hello ssjsonic,
there are many places in Singapore to play, but depending on where you from, the system in which they are organized can be a little bit diffrent from what you are used to.
There are no public clubs but mostly everything is private so you need an invitation to play there. It is like in most asian countries, you need to know someone who knows someone aso..
But you are going there to study, so you should check out the tabletennis club of your university/school first.
Oh and check out 'sgpingpong.forumotion.net' there you'll find many 'kakis' who are intrested in meeting and playing a good match!
And depending on where you live in Singapore be prepared to travel about an hour! Most action goes in the east, around Tampines area.
This information should be at least enough to get a grip in the singaporian tabletennis scene, if you need more detailed informations, just ask me.
Whish you lot's of fun playing and have good and fertil studies! ^^
