Quite a bold move, for anyone claiming the bonus, I suggest you just go to the slot & play as usual, without realizing you will have exceeded the TO that must be achieved.
Why it's a bold move ?
The angpao reward around IDR 10,000 - 50,000. It's quite small, no really needed to scared at all for betting these amount. Unless you're betting more than 50-100$. Then it's consider a bold move.
For me, I just don't want wasting to much money for a small bonus.
