"SET" is a card game that I used to play with my son. I am not the sort of mom who would take a dive in order to allow him to win, and am embarrassed to say that Matt would regularly (as in "almost always") win when playing against me.
The deck of cards in the game of "SET" consists of 81 unique cards that vary from each other in their features.
There are 4 features and 3 possibilities for each feature on every card.
- Number of shapes: 1, 2, or 3
- Shape: ovals, diamonds, or squiggles
- Color: red, purple, or green
- Shading: solid, open, or shaded
Each possible combination of features appears only ONCE in the deck of cards.
To play the game, certain combinations of three cards make up a set. For each feature (number, shape, color, shading), the three cards in a set must have each feature either all the same OR all different.
To solve this puzzle, you must identify the 6 unique "sets" among the following cards. Make note of the features of the cards in each set. (Each card can possibly be used in more than one set.)
Once all 6 sets have been identified, count the features that are found among each of the cards in all six sets to solve for the coordinates where this geocache can be found.
Please read these instructions carefully!
Use the following formula: N 41 18.ABC W 081 44.DEF
A= Number of times the card featuring three purple squiggles is used minus the number of times the card featuring three red solid diamonds is used
B= Number of times the cards featuring open shapes are used plus the number of times the cards featuring two shapes are used
C= Number of times the card featuring green open diamonds is used plus number of times the card featuring solid shapes are used
D= Number of times the cards featuring two green shaded diamonds is used
E= Number of times the cards featuring shaded shapes are used
F= Number of times the cards featuring red shapes are used minus the number of times the cards featuring purple shapes are used minus the number of times the cards featuring squiggles are used
Please bring a pen with you to sign the log, and camouflage the geocache with natural material before you leave.
