Chalices

On the Subject of Chalices

You should always wait for the other person to drink first.

You are sent to the killing floor and your seven friends are smart enough to poison seven different chalices. You must drink from the non-poisoned chalice in order to survive.
To determine which chalice is safe follow the flowchart below and its corresponding rules to determine which chalice to drink from.
Cup positioning and order rules can be found beneath the rules tables.
Start at the question mark in the center starting with the northmost facing arrow go to the next clockwise arrow for each port on the bomb and follow the rules from there.

	If the first condition is true, follow the red arrow. Otherwise if the second condition is true then follow the black arrow (if available). Otherwise follow the white arrow.
A	If the Skull Cup is left of the Wine Glass. If the Party Cup is right of the Skull Cup.
B	If the Tall Glass is placed at an even position. If the Metal Chalice is placed at an odd position.
C	If the Exotic Cup is not adjacent to Tall Glass. If the Shot Glass is adjacent to Wine Glass.
D	If the Mug is at a prime positioned spot. If the Skull Cup is at the spot corresponding to the last digit of the serial number.
E	If there is a sequence of Party Cup, Skull Cup, and Mug. If there is a sequence of Exotic Cup, Wine Glass, and Tall Glass.
F	If the Metal Chalice is two spots away from the Tall Glass. If the Shot Glass is left from the center.

H	If the Party Cup is at any of the following positions: 1,6,7,8. If the Mug is at any of the following positions: 2,3,4,5.

I	If there is a lit indicator with the label of “BOB.”
J	If there are exactly five batteries.
K	If the serial number contains a vowel.
L	If there is an even number of battery holders.
M	If the serial number contains any letter in “TMP.”

Cups are ordered from 1–8 in reading order.
Instead of considering the cups in the order given on the module, consider them as one continuous string, where the rightmost cup of one row is adjacent to the leftmost one on the next row.
- This string does not connect the top and bottom rows.
