My grandfather had this made of wood. I replicated it with my 3d printer. The object is to switch the big square with the horizontal rectangles by sliding the pieces. I don’t think i ever knew what it was called. Over the years I have forgotten the solution also. I can remember bits and pieces of it but not the correct order. Any help would be appreciated.
Hi there,
I have made a new puzzle games that takes elements of quizzes, maths, logic and word games and tries to make a cocktail of fun – keen to hear what you think?
A dizzy sailor is standing on a 15×15 square tiled board. From their initial square they are able to move to any square sharing a common side. Due to the sailor’s dizziness, after every move they immediately make a left or right turn before repeating this process (that is, they are never able to enter and exit a square in a straight line). What is the largest number of squares the dizzy sailor can walk on if they are not allowed to repeat squares and the last step of their path must end at the square they started at?

This is a html code for a game. It displays 10 numbers vertically with two buttons on either side of each number- blue and green. If blue button is clicked, The entire sequence from where it is clicked gets reversed. If the green button is clicked, That number is exchanged with the next number. Once the button is clicked, It will disappear. That is, Each button can be clicked exactly once. The goal is to arrange the numbers in ascending order using those buttons. Proving that it is always possible to arrange the numbers in ascending order, is also an interesting question…
Here’s an interesting puzzle that you can do with a pack of cards. Start with the cards 1, 2, …, N, where N is some whole number. If you’re doing this with cards, then you might count the Jack as 11, the Queen as 12, King as 13. Let’s say, for purposes of this example, that N=5, so you start with the Ace, 2, 3, 4 and 5 of diamonds (Ace being 1). The aim of the puzzle is to play all the cards to the table obeying the following rules:
1. The first card played must be the highest card, the 5 of diamonds in this case.
2. Subsequent cards can only be played if they are a divisor of the cumulative total of the cards currently on the table. A divisor is a smaller number that evenly divides a larger number.
In the present example, a valid sequence of plays would be 5 (5), A (6), 2 (8), 4 (12), 3 (15), where I’ve put the cumulative total in brackets afterwards.
It gets progressively harder as N gets larger. Also, for N>13 you tend to run out of cards, so you have to do it in your head! I got up to N=23. How high can you go? Maybe post your solutions below so that we can compare.
