I will make my picks just before 8pm Friday, May 28th. I'll post the rules later tonight or some time tomorrow. They will be the same as previous mastermind games. I am asking that only persons within North America play in an effort to save a bit on shipping, but I am not going to prohibit those outside this area from playing. The prize for my game is a roll of 2009 Canadian pennies taken from a box that I purchased last year (see pictures below. It is a head/tails roll. The tails end penny has been pressed through grease (again, see photos).    This is my first game, so here's hoping I get it right.  Edited by rikcando

Here is the list I've chosen :
AUD Australian Dollar
CAD Canadian Dollar
CHF Swiss Franc
EUR Euro
GBP British Pound
JPY Japanese Yen
MXN Mexican Peso
NZD New Zealand Dollar
RON Romanian Lei
SEK Swedish Krona
SGD Singapore Dollar
USD US Dollar
USZ Uzbekistani Sum
********** Currencies add by Ian Price ********************************************
IQD Iraqi Dinar
GRD Greece Drachma
VND Vietnam Dông
DKK Denmark Krone
SZL Swaziland Lilangeni
*******************************************************
For those of you not familiar with the game:
Someone (in this case, me) selects 10 currencies and arranges them in a certain order (NO duplicates will be used!).
The players (y'all) - yes, I'm from the south, try to guess which currencies and in what order.
After each guess, you will get clues as to how many are correct in total, and how many are in the right position.
But, it's up to you to figure out which ones!
Let's take a test run:
Let's say I've chosen: MXN, JPY, XAU, USD, CHF, GBP, EUR, GRD, VND, DKK
And the first guess is: AUD, CAD, XAU, NZD, GBP, SGD, XAG, IQD, SZL, SEK
Then the clue would be 2 right in total (XAU and GBP) and 1 in the right position (XAU).
But, again, all you will get from me is 2 correct, 1 in the right position. You have to figure out which is correct and in the right place.
One guess per person per day. 1 day will be defined as midnight EST.
*** Exceptions:
(A) If you post a reply that has too many or not enough selections, you may repost with the correct number of currencies. DO NOT EDIT YOUR POST - just repost.
(B) You can take a second guess in the same day, but it will be your final answer. If you are wrong - you are eliminated and can no longer play.
I hope you like this game, and maybe someone else will use it again in the future.
It is really fun and is a good exercise for the brain.

Just out of curiosity.. how many permutations of 10 are there from 18 available items? I calculated 17,643,225,600 - is that correct?
Supposedly this is high school algebra, but I do NOT remember !

I'm coming up with ONLY 158,789,030,400 possible combinations. Of which the correct 10 can only be arranged in 3,628,800 ways. And we can figure it out in around 15-18 clues! Amazing!
Professor will confirm the true numbers, but that's what I'm coming up with.

Professor, if my numbers are correct, does that mean that there are only 43,758 "groups" of 10 that can be arranged in any given order?

I just love that "only" Scooby.. lol!
And.. if you have 10 items and you have 10 slots, then it should be 3,628,800 possibilities. I think.

I must be tired, I just noticed you gave the same number of possibilities for 10. I was looking at your "groups" number - which I don't get ;) If we came up with the same number for 10/10, why different for 18/10?

I think you stopped at 10 instead of 9. (18*17*16*15*14*13*12*11*10) is only 9. You need (18*17*16*15*14*13*12*11*10*9). And since any 1 group can come in (10*9*8*7*6*5*4*3*2*1) dfferent ways, if my thinking is correct then (18*17*16*15*14*13*12*11*10*9) / (10*9*8*7*6*5*4*3*2*1) = 43,758 different "groups" of 10 currencies in any given order.

Although the professor would probably prefer (18! - 8!) / 10!, I think.  |

Or P(18,10) ! I thought you only go to the number of slots So if you have 8 numbers but only slots for 6, you would do 8*7*6, rather than 8*7*6*5*4*3*2. Wrong? I'm sure he'll let us know in the morning (along with berating us both for mathing without proper instruction!) |

Looks like Scooby is the winner of the math quiz.

More than likely  The part I'm confused about is the continuing to *9... maybe I should go back to high school. errmmm... no. |
