2. ## The Parlour Game

The thirteen party kids shall guess each others birth months without telling their own, but each only knew the others by the name tag on their hats. Every participant can make a flag from a drinking straw with card length cut on one end and a selected card from a pack of new deck. Then the flags are collected into a paper cup on the table (see figure). At random each player will be asked of anyone's birth month. Super awesome prizes awaits all if they score 13 points ! How can they win this game?

9. ## Marked Hat

Correct, they must wear the hat with marker stucked already when going outside their cells. When they are on the yard or mess hall, the act of wearing or taking off the hats or sticking the card on hat can be mistaken as trying to communicate. Lots of suspicious eyes and ears around. It looks like the information they needed must be just on the marked hat alone. There is a clue in the OP.
10. ## Marked Hat

I dont see what the days of event has to do with the strategy as long as they occur within the week before execution but not on just one day. Say they happened : 1. the death sentence -Sunday 2. warden's clemency announcement and conditions (OP)-Monday 3. plan agreement -Tuesday 4. random schedules of execution - Wednesday 5. card selecting-Thursday 6. wearing of hats-Friday 7. writing the guess list-Saturday 8. escaping or hanging-Sunday (sunrise to sunset)
11. ## Marked Hat

But that can't be right. It's too simple. I'm probably missing something...? No, it is just unlikely solution..can you give it another go? .
12. ## Marked Hat

Order of event: 1. the death sentence 2. warden's clemency announcement and conditions (OP) 3. plan agreement 4. random schedules of execution 5. card selecting 6. wearing of hats 7. writing the guess list 8. escaping or hanging (the warden would make the release look like an escape)

17. ## Marked Hat

The warden will release the 7 prisoners to be hang on everyday next week if they can mark their hats with a number card from a playing card deck so that anyone may see and guess right the others prisoner's day and time of executions. The cards shall be erected on hat through a small straight cut on top. The schedule will be randomly drawn for everyone. No prisoner must tell his scheduled day (Sun,Mon..Sat) and hour of execution (1:00,2:00,3:00 ... 12:00). Since these prisoners had freed themselves a couple of times on this same prison it should not be hard for them to agree on a plan. What code strategy works for them?

19. ## Governors of Poker

The twenty two inhabitants of El Paso will vote for their favorite poker player as the new Governor.. Four candidates are running for election: 1. Speedy Deal 2. Damon Blinds 3. Heather Raise 4. Clover Call Each voter picks a card from an official deck as a valid ballot..The first one to cast a vote at the precinct place his card on ballot box in front of the tally official. And to cast a vote the others place their card on top of the previous voter's card. If this was a sucessful electoral process.. how did the voters vote?
