Presentation:
Teams are given a seemingly-normal deck of cards. The deck contains 48 cards, 2-suited, A->Q. The cards are custom printed with "CAMP NORTHWIND" on the back of each card, with each containing a triangular hole in unique location.
Walkthrough:
Each individual card contains a hole. Within the entire set of 48 cards, there are 6 distinct rows of holes, with 8 holes per row. Each hole is in a unique position.
Arrange the cards based on the "row" that the hole is in. This will divide cards up into 6 sets of 8 cards each.
Arrange the cards so the holes align for each row of holes. This will arrange them such that only the red/black numbers are visible for each card (see below for specific ordering).
Once this is done, decipher that the red corresponds to "1" and black corresponds to "0" in binary.
Convert the binary to ASCII, spelling "crazy8"
The ordering of cards is below.
| c:01100011: | 2s,Ad,10d,Qs,3s,6s,9d,7d |
|---|---|
| r:01110010: | Qs,3d,7d,5d,7s,8s,Jd,6s |
| a:01100001: | 8s,4d,3d,5s,Js,10s,2s,Qd |
| z:01111010: | 5s,9d,Jd,Qd,2d,4s,Ad,7s |
| y:01111001: | 3s,8d,4d,2d,6d,As,Js,10d |
| 8:00111000: | 9s,4s,6d,5d,8d,10s,As,9s |
Hinting:
Usually just suggesting "binary" will put them on the right track to solving.
If they are ordering the cards for use in binary, you can verify their ordering is correct by using the above table.
Changes Since Beta/RC:
The holes are triangular instead of circular, providing an orientation for the cards.
