In this small game, you're standing outside a 'Game Hall Emporium' in Las Vegas. A certain Mr Bell invited you here to win a lot of money, a once in a lifetime opportunity you couldn't ignore. Bell's message was light on details, but you do want to be wealthy. You just hope your phobia won't get in the way.
This solution is by David Welbourn, and is based on Release 4 of the game.

Attack the gameshow host before he notices you're there. You don't want him to remove the sheets from the other two doors, because when there's three doors, you can't choose any of them.

Boss' Office
You only have three turns until the man finds you in here. If you're inside the cabinet (or desk), and if the door is closed, he won't find you.
> close door. x computer. enter cabinet.(Bell passes through.)

The notes are a list of clues describing a three-digit number. The only number that fits all the clues is 594.
> leave cabinet. turn painting. set lock to 594.
> open safe. take diamond.("Cullinan")
*** You have won ***
Explaining some of the more confusing post-it-notes clues:
"The sum of the invididual numbers in the sum of the invididual digits is 9." — 594 satisfies this clue because 5 + 9 + 4 = 18, and 1 + 8 = 9.
"The digits have a total of two enclosed areas" — The digit '8' has two enclosed areas, and the digits '4', '6', '9', and '0' each have one. In some fonts, a '4' doesn't have an enclosed triangular area, but please assume we are using a font with a closed '4'.
"The sum of two digits is equal to the sum of all digits divided by two." — In other words, the sum of two of the digits equals the third.
"The number can only be halved twice before becoming a decimal number." — This clue is trying to say that the number is evenly divisible by two, but not by four.
Extras
Characters
Gamm Bell is the man who invited you here in the first place, and he's also the man who zips in and out of office for a few minutes at the end of every hour. He will also angrily and permanently evict you if he finds you inside his office, or even near his office door when left open. I have no idea what he expected you to do when you arrived at the building.
A receptionist occupies the desk in the foyer. You can ask her about Bell or the glass door.
A gameshow host with a punchable face is in the contest room.
Two men are in the toilets. One is using urinal 3 and the other is using urinal 6. Those poor chaps will be there for hours; don't bother them.
Mentioned:
Monty Hall is referenced. The keycard and dusty suit are his, and the "M.H." on the wooden door refers to him. He's best known as the game show host and producer of Let's Make a Deal. (See Monty Hall at Wikipedia.)
Some men employed by Bell crashed the car, wrote the letter, and returned the keys.
A goat is presumably behind both doors 1 and 3 in the contest room.
"Cullinan" is on a tag attached to the diamond. You wonder if that was the diamond's previous owner. (See Cullinan Diamond at Wikipedia.)
Endings
You lost your opportunity
if Gamm Bell finds you in his office.
if Gamm Bell finds you at either end of the corridor when his door is open.
You have won
when you take the diamond.
Inventory
a keycard. Find it by searching the dusty suit in the unlocked locker in the locker room.
In the waiting room, swipe the keycard in the device to unlock the wooden door.
a keychain. It's on the table in the prize room.
The keychain unlocks the door at the far end of the corridor.
a letter. It's on the table in the prize room.
Read it to learn why there's no car there.
Honorable mention:
a diamond. It's in the locked safe behind the painting in the boss' office.
Turn the painting to reveal the safe. Set the lock to 549 to unlock the safe; this is clued by the post-it notes on the office's computer monitor.
Taking the diamond ends the game in victory.
