From an ordinary deck of playing cards remove cards ace to nine of any three suits (27 cards in all), and place them in a row so that between any 2 consecutive aces there is precisely 1 card, between any 2 consecutive twos there are 2 cards, and so on, up to 9 cards between any two consecutive ni...
This puzzle is based on the framework described here:
Controlling a robot blindfolded on a 9x9 grid
Here is a quick summary. A robot is located somewhere on a grid, but you cannot see it. You can send commands to the robot to make it move one cell left, right, up or down. Some cells can be walls...
The ants from this puzzle have been placed into a new arena: a cross-shaped hallway with a pillar (black square) in the centre and four statues (numbered 1-4) set symmetrically.
The ants, like last time, start off by trying to move East. If they encounter a boundary, the central pillar, a stat...
And then I Googled for songs sung by Jesus, and apparently Mark and Matthew say he sang but don't say what he sang, and some Web page suggests certain psalms he would've sung, but that seems too far a stretch and anyway I don't know what word it would clue.
THRENODE is another spelling of threnody, which is a song of lament that has a king (R = rex) in THE and then NODE, a reversal of EDO castle and N (endless (du)N(es))? If so, I think the reversal is a bit off.
@MOehm I dunno what you mean by "off". "About" can mean "reversed" (as in "about face"), but then the components are out of order: should be "endless dunes castle about", if you will. (Plus, as already mentioned, it uses "endless" for grabbing the middle letter of a five-letter word.)
I mean that if it is really NODE = (EDO + N)<, then the reversal indicator "about" is in the middle, which doesn't feel quite right. And I find those synonyms very loose, especially since the dunes don't have any relation to the rest of the surface.
But as I said, It's a stretch. I do like the "King in the" part, though.
(Perhaps I ike it so much that I try to make rest of the solution fit, no matter what.)
"You know these tiny travelers?" say Grandpa
"Billions of them! Born to travel. They have travelled to all
continents, nations, and towns."
"But they always need help, a chaperone so to speak. And, it is almost
always a one way ticket for them." Grandpa said.
"They love their co...
There are 100 cards on a table numbered 1,2,...,100. What is the maximum number of cards, which can be selected such that no two cards have a product, which is a perfect square?
Example: you cannot choose the cards with number 27 and 48, as $27*48=81*16=36^2$
A bored jailer tells a prisoner that if he can guess a secret number he will be set free. The rules are given that the number will not be more than three digits in length and the prisoner may guess the number as many times as necessary, as long as his guesses meet the following requirements each ...
I'm having the hardest time with this sequence puzzle. The mobile game I play (which asked me the question) doesn't provide answers or explanations for incorrect answers, and I'm searching online so I can better understand it.
What comes next in this numeric sequence:
5, 13, 7.5, 9.5, 10, 6, 12...
