mercenary007 Apr 12, 2006	that was very easy... didn't pick it up at first but once I read the clue I knew instantly what was going on...
boodler Apr 12, 2006	I have no idea here! Enlighten me please?
signmeup74 Apr 12, 2006	What game? Craps?
sahana Apr 12, 2006	That was easy..
calmsavior Apr 12, 2006	the game is called "buzz" and what you do is a group of people sit around in a circle, and one of them starts by saying "1". The next person (clockwise) says "2" and they keep going until they come across a number divisible by 7 or contains a 7: in which case they say "buzz". Anyone who screws up by unnecessarily saying buzz or not saying it when they should, they are out and everyone continues until only one person is left. He/she is the winner.
calmsavior Apr 12, 2006	by the way, they start counting over each time somebody is out.
calmsavior Apr 12, 2006	back to 1.
TheEarthling Apr 12, 2006	Very easy.
boodler Apr 13, 2006	You are my saviour! 'Q
Draw Apr 13, 2006	Why should they start counting over each time somebody is out? I think they should continue, because people are more likely to make mistakes in larger numbers.
ashjbom Apr 13, 2006	thats dumb. what game?
Psychic_Master Apr 16, 2006	Yeah this was really easy for me because I play it at school for Maths every week. It's a fun game and I usually win. Good riddle, I guess, although too easy.
JoannaFruity May 02, 2009	I saw it! I just couldn't say it into words? lol
jimbooth019 May 02, 2009	I got the multiplication of 7 quickly, took me a little more studying to get the 7 as second digit. good one!
bradon182001 May 02, 2009	Never heard of the game, would never have figured this out. Quite a challenge. Thanks for posting.
FatHead May 02, 2009	The hint was worthless but I still figured it out.
kasiecom May 02, 2009	If you follow the sequence of the sequence of a number ending in 7 and the number following it be divisable by 7 should the 7 and 8 numbers in the sequence be 37 and 42, NOT 35 AND 37, therefore making the correct answer to the braingle 47 and 49. EXPLIANATION first 7,14 second 17,21 third 27,28 fourth should be 37, 42 and not 35 and 37 therefore fifth in sequence 47, 49
Cubano May 02, 2009	Kasie, you are changing the original sequence, which would negate the whole teaser.
jcann May 02, 2009	Kasiecom, why skip 35? It is divisible by 7.
UptheHill May 02, 2009	NICE!!!
avonma May 02, 2009	I KINDA got it, but got the numbers wrong. I keep telling you I'm "numerically challenged!" I might as well delete the quiz when it has number in it!
(user deleted) May 03, 2009	very easy
composer May 04, 2009	The number 7 isn't the only one used, it's just the toughest for younger kids. Any (single-digit) number can be used. A variation of the game is Bizz Buzz, where two numbers, say 7 & 4, are used. Players say "Bizz" on the sevens, "Buzz" on the fours, and "Bizz Buzz" on the numbers divisible 4 & 7 or have 4 & 7 in them.
(user deleted) May 06, 2009	Very easy. I enjoyed it only because the unknown numbers have some symbolical value to me.
kittygirl19 May 02, 2012	Se7en
Maggiethe8th May 02, 2012	Made me feel less math challenged-thank you!
gaylewolf May 02, 2012	I got it, too, and was happy for the same reason as you, Maggie! Happy MAY and good health, every one!
eamon May 02, 2012	For those of us who never played that game or ever heard of it, the puzzle was totally random. The hint only acted as a misdirection for the same reason - you had to have played that game to get it.
thecatladycac May 02, 2012	I've never heard of the game, but I did figure it out - sort of. I started with "7" and every other number added 10 (7-17-27, etc); the interspersed numbers were multiples of 7 - except when I got to the last 2 numbers (35, and 37) they were backwards - I thought that was a typo and turned them around - so I still got the right answer! good quiz!!
castia123 May 18, 2012	guys when I saw the answer I thought that it is wrong .. someone should light me ... which is right answer (42,49)"it is mine" or (42,47)"the written one" ????
