Let me help to answer this question.
Let's say the no. is just normal no. e.g.: 9527
Normal no. needs at least RM300 + RM10 = RM310 to bid.

But before you start, you need to pay RM10 (non refundable) in order to participate in that particular no.
You can participate as many numbers as you want but for each number, you need to pay RM10.
Of all the number that you bid, as individual, you can only win the bids for 3 number.

After you have participate in 9527， then only you can roughly guess bid this number is in.
By default it's RM300 for 1st bid.

If the current bid is RM 826, which you won't know, you need to start from RM300.
The system wills show that your bid is lower.
Then you try RM600, system will show underbid also.
Then you try RM1000, system will say you can place the bid.
Just don't pay first.

Then you can try to reduce to RM900. System will say you can place the bid, don't pay first.
Then you can try at RM800, system will say your bid is lower.
Then you can try to increase RM10 until RM830, then you know the actual figure is between RM820-RM830.
Of course you can try from RM820, 821....until you can successfully guess the figure.
Anyway, after you have bid, after a while, the system will show that your ranking in the bid.

If you remain the 1st until the bid ends, then you win the bid.
However, for popular no., the bid will shoot up very fast at last minute, I have seen myself, it's crazy.

Whenever you bid a no., the system will hold the money first.
Transaction will be done after 24 hours the bid has completed.
This is what I know.

Take it example, you bid 1111, RM4,888.00.
You will be brought to payment page.
You will pay RM4,888.00, the system will hold the payment 1st.
If in the end of the day (bid), you are the 1st bidder, then the RM4,888.00 will be gone through the system by default.

If you bid all 3 numbers and you are the highest bid, you all have pay for all 3 no.
So far there is no way to get refund so far.

This is Malaysia, you know, some people might just back off.
To prevent that, the system has to ensure the bidder is willing to pay by holding the payment.

I'm new to this. I tried logging into ebid, it mentioned i need to register at JPJ for an ID also. can clarify on this?
