# Eye the bull's-eye!

Not too long ago, while I was hanging around in a sports club playing darts, I met a friend. We talked for a while. When he suddenly came up with an idea of a puzzle. He grabbed a piece of paper and noted down something which looked like a cipher. He stood up and asked me to meet once I decipher the note. I asked him "But you didn't tell the place to meet?". He just smiled and said "Eye the bull's eye" and took off.

The note looked like this -

Can you help crack it?

• Aargh! I was trying out stuff with the thing you've just clarified. rot13(Gur gvgyr naq gur zrffntr yratgu znqr vg boivbhf rabhtu, va zl bcvavba.) Commented Mar 16, 2017 at 18:21
• @M Oehm I thought it didn't got much attention and hence thought I made it ambiguous. :) Commented Mar 16, 2017 at 18:24
• Well, for all my trying out I haven't gone anywhere so far, so maybe it wasn't that big a giveaway. Commented Mar 16, 2017 at 18:26
• @M Oehm Okay cool. All the best :) Commented Mar 16, 2017 at 18:36

Your friend wants to meet at ...

McDonald's

Here's why -

Dartboards have scores ranging 1-20 around the outside; clockwise from top-center, the scores are 20 1 18 4 13 6 10 15 2 17 3 19 7 16 8 11 14 9 12 5

Wrapping the message around the dartboard, starting from the "1" which seems a sensible starting point, the letters map thus:
1=F, 18=L, 4=I, 13=T, 6=L, 10=K, 15=O, 2=T, 17=B, 3=R,
19=E, 7=P, 16=U, 8=V, 11=E, 14=R, 9=L, 12=Y, 5=O, 20=S

Now sorting those numerically, you get this:
1=F, 2=T, 3=R, 4=I, 5=O, 6=L, 7=P, 8=V, 9=L, 10=K,
11=E, 12=Y, 13=T, 14=R, 15=O, 16=U, 17=B, 18=L, 19=E, 20=S
or:
FTRIOLPVLKEYTROUBLES

Decrypting "FTRIOLPVL" with Vigenére key "TROUBLES" gives:
MCDONALDS
