On the Subject of Secret Santas

Presents are the best way to show someone how much you care. It is like this tangible thing that you can point to and say, “Hey man, I love you this many dollars worth.”

• Each of the six presents arranged in the circle has a box color, ribbon color, and a sound when shaken. This sound indicates the gift that is inside the box. Each gift has a value between $10 and $99 in value.
• The price ceiling and price floor have both been predetermined before the exchange, but exactly one person has gone over the maximum and exactly one other person has gone under the minimum. Only one price tag will display a price that is a valid price ceiling or valid price floor. Press the box containing this price tag to solve the module.

Gift Name	Initial Price	Gift Name	Initial Price	Gift Name	Initial Price
Handball (10)	$10	Wine Glass	$15	5L of Soda	$18

Pipe Bomb	$55	Tortured Soul	$59	Gold Marbles	$73
Toy Piano	$79	Marimba	$80	Discord Nitro	$95

• The initial value for each gift must be modified first by its ribbon color. Use the item’s position in the above table, shifted via its ribbon color:

Reverse the digits.	Do nothing.	Average with $50, drop decimals.
Add the digital root*.	Reverse the digits.	Add $20.
Subtract $10.	Add $10.	Reverse the digits.
Reverse the digits.	Subtract $20.	Subtract the digital root*.
Divide by $5.	Reverse the digits.	Subtract from $100.

	Gold
Silver	✥	White
	Bronze

• For each gift giver, take the color of the gift currently in their position, add the digital root of its current calculated value, and call this T:
  • If the gift currently in the recipient’s position has a calculated value of less than $45, subtract T from the recipient’s gift’s value. If this would result in the gift’s value being less than $10, add T instead.
  • If the gift currently in the recipient’s position has a calculated value of $45 or greater, add T to the recipient’s gift’s value. If this would result in the gift’s value being greater than $99, subtract T instead.

Red	12	Green	25
Orange	15	Blue	18
Yellow	22	Purple	7

*The digital root is the repeated sum of digits in a number until said number is a singular digit long.
