Hi everyone

I saw the "add x" threads and thought about the following

chain puzzle. Hope some of you will like it :-)

______________The puzzle________________

My numbers are between 1 and 99.

Glued together, they give the sequence S (S must have no more than 10 digits)

Their sum (or mean) is ...

There are often multiple solutions, so one may add additional

constraints/hints (one of my numbers is a prime/Fibonacci number, etc.)

_____________A Simple Example___________

My numbers are between 1 and 99.

Glued together, they give the sequence 15723

Their sum is 81

Solution 1 : 1 57 23

Solution 2 : 1 5 72 3

I could have added the following constraint/hint

- At least 2 of of my numbers are Fibonacci numbers

to make Solution 2 the only valid answer

_____________First Puzzle____________

My numbers are between 1 and 99.

Glued together, they give the sequence 23931897

Their sum is 195

Constraints/Hints:

#1 At least three of my numbers are prime numbers

#2 At least one of my numbers is a 2-digit Fibonacci number

***** ANSWER FORMAT *****

Answer to previous:

My numbers are between 1 and 99.

Glued together, they give the sequence ... [10 digits or less]

Their sum/mean is ...

Constraints/Hints:

#1

#2

Hi anonimnystefy

Congrats for the solution.

Now, you get to propose your own puzzle

You just have to think about some numbers in your head

and complete the answer format.

A cool thing is that you can draw attention

to a number (between 1 and 99) with some special properties

(anyone who solved the puzzle can continue the chain)

I think I'll leave it to someone else to come up with a new puzzle.

66 + 2 + 6 + 71 + 1 + 5 = 151

71 = 66 + 5

6 = 1 + 5

My numbers are between 1 and 99. When glued together they become 171975913.

Constraints:

#1 At least 2 numbers are prime.

#2 The sum of my numbers is a square.

Hi bobbym

You need to give the sum of your numbers as a value.

You're right anonimnystefy

but what he did is a cool variant. I enjoyed solving it.

If there is no other answer, I will add my own puzzle later today.

That is one answer but there is another one.

Answer to previous

Pascal-themed puzzle

My numbers are between 1 and 99

Glued together, they give 919236295

To get the sum of my numbers, you have to get a list of the first prime numbers

and retrieve the position occupied by the prime number obtained by dividing Pascal birthyear by 3.

(phew, I'm not even sure this is understandable :-D)

Constraints/Hints

#1 One of my numbers is the monthday of Pascal's birth and death

Hi meanmaths

I've seen less understandable. I think Bob and phrontister can confirm it.

well done, anonimnystefy.

(You give me more work though because I have to build another puzzle to make up for the one you didn't provide :-P)

Sorry about that.

Anyone willing to can pose a new one instead of me.

What type puzzle is required? The old type or the Pascal theme?

any puzzle will do, bobbym. The initial version, your version, or a version themed around a mathematician/scientist you admire, etc.

The cool thing with the themed version is that it gives an additional tiny bit of mathematics culture/trivia to the people who try to solve it.

The less cool thing is that it requires more time to build, compared to the simpler puzzles.

Hi meanmaths

Look at this one:http://www.mathisfunforum.com/viewtopic.php?id=19273. You might find it interesting.

Hi stefy

I read all the thread (except the hidden parts). Some bits were quite funny :-d

My take:

1) This chain is not really for puzzles that seem so hard :-) so when I said, "any puzzle will do", it should not be believed

2) The warning message accompanying the puzzle is just too convincing. I'm already late for too many things and I don't

really feel like coding to solve the puzzle [I have saved the pdf though. I may try to do it manually some day]

Hm, so have you read the puzzle itself?

well, I just did. Funny stuff. Great headache material :-D.

(English is actually my third language, so the pain was possibly greater than "intended").

I see your point now about having seen "less understandable" puzzles.

Note that I sometimes do this kind of things too (making all sorts of factual but

arguably pointless connections between this and that) but that puzzle is a masterpiece.

I would add that the puzzle actually has some similarities with Mean Sumurai. And I could see also on the "Add 13" thread that bobbym was splitting numbers long before I joined the forum.

So, bobbym, if you have an Android, there is a new Mode Arena that you could like. I would like to see how you fare against games that I (or Jess Chua, a player that may be better than me at my own game) solved and uploaded.

Hi;

The 13 game gets much more complicated when phrontister and I play it. When he is not involved I go with the idea of simplicity and leave out the more extreme possibilities.

I do not have an android but would not have offered much competition anyway.

Hi bobby

I actually do the opposite for the 13 game (I always try to give the simplest answer).

About the number splitting thing, I believe a master Jedi such as Yoda ;-) would have made,

at the very least, a great Sumurai.

Yoda is a little bit passed it. Maybe 500 years ago he was the man ( the frog ) now he is pretty much running on fumes.
