How to "operate" the lottery?

You can set a hidden box in the lottery box, so that you can secretly put the winning numbers there; Or let his number chip be folded into a special shape and let the lottery draw that chip; You can also make an extra copy of the winner's money and give it to the lucky draw in advance to pretend to draw a lottery.

These all need your staff to operate well internally in the early stage, and then the lottery will cooperate with them to perform the drama → otherwise it will be too fake. However, it is best not to let too many people know about this kind of thing, and the drama should be done as well as possible. You or your boss should be the lottery winner.
