Only the top ball moves. It can go into any tube with free space (max 5 balls), whatever the color, and there are no empty tubes to use as a buffer. Target: every tube ends up exactly like the goal, bottom to top blue, orange, pink. Minimum is 10 moves. Please put your solution in spoiler tags (moves written like 3→2). Puzzle is from my game Ball Sort Pattern.

A challenge math question to all.

1 Upvotes

if we have a 4x4 grid of squares in which we can place letters of the English alphabet, one in each square then find the maximum number of possible 4 letter words formed if repeating letters is allowed. for example.

A F A T

B E S H

M R X E

G D F E

rule to follow: if you choose a letter tile for the starting letter of your word you must choose the tile adjacent to it ( diagonals count) for the second letter of your word and continue until u get a 4 letter word. for example, in the example above if you choose F as the first starting letter u must select any 5 of the tiles surrounding it as the next letter of your 4 letter word. by choosing F then A then T and then S , you get FATS so like this you must form 4 letter words and have to find the maximum number of 4 letter words possible if repeating letters is allowed( as shown, A is repeated in example and so is E)
