| Jun 28, 2010 at 1:27 | comment | added | JBL | Yes, you're right -- I just hadn't figured out how to adapt the solution for 26 to other numbers: Qvivqr gur qrpx vagb bar cvyr bs fvmr gjragl-guerr naq bar cvyr bs fvmr gjragl-avar. Abj ghea gur svefg cvyr hcfvqr-qbja. (Naq bs pbhefr 23 vf neovgenel urer.) | |

| Jun 27, 2010 at 3:09 | comment | added | JBL | Are you sure that 23 isn't supposed to be 26 (half of a deck)? | |

| Jun 24, 2010 at 18:15 | comment | added | Vectornaut | @Kiochi: you really should mention this in the answer. I've edited it for you, hope that's okay! | |
| Jun 24, 2010 at 16:54 | comment | added | Kiochi | Although I should mention that you are allowed to flip as many cards as you please. | |
| Jun 24, 2010 at 16:53 | comment | added | Kiochi | @Roland: Each stack contains the same number of up-flipped cards, not necessarily 11.5 (in fact, definitely not, as ripping cards is destructive). – Kiochi 0 secs ago | |
| Jun 24, 2010 at 16:17 | comment | added | Roland Bacher | You mean each stack contains exactly $11.5$ cards which are up-flipped? Am I allowed to tore every card into two equal pieces? | |
| Jun 24, 2010 at 14:40 | comment | added | ADL | I really like this one. I heard it a few years ago, and remembered my solution because it was neat. However, I had forgotten the question (and have been intermittently searching the internet for it) until now. Thanks! (It is a bad thing to have an answer without a question floating around in your head!) | |
