October 22, 2026 · #434: CASH to POOP

CASH begins with none of the four letters in the right position for POOP. That makes four changes an obvious lower limit, but it does not make a four-move answer possible. Every stop between the two ends must also be an accepted word. This route needs five changes because one position has to change twice. The third letter starts as S, becomes O, and stays there; the fourth letter travels from H through T before it becomes P. That extra stop is the part a simple letter count misses.

The opening CASH to COSH keeps C, S, and H in their original positions while replacing A with O. You now have the second letter of the target without disturbing the shape of the starting word. COSH may be less familiar than CASH, so this is a useful place to slow down and read all four letters. You do not need to rearrange them or add a letter. The next word, COST, changes only the ending. Although T is not part of POOP, that temporary ending lets the route continue.

COST to COOT is where the middle pair becomes OO. Compare the words vertically if the change is hard to see: the first C, second O, and final T remain fixed, while S becomes O. The ladder now has two target letters in place. Moving directly from COST to COOP would skip this stop and change both the third and fourth letters. Both endpoints being real words would not make that skipped move legal. Keeping COOT in the route preserves the one-letter rule.

The last two moves finish the word from the outside. COOT becomes COOP by changing the fourth letter from T to P. COOP then becomes POOP by changing the first letter from C to P. At COOP, three positions already match the target, so the final move is easy to check. Count the arrows rather than the displayed words: six words make five moves. CASH is the given starting point and does not itself use a move. POOP is the result of the fifth change.

For another attempt at this particular puzzle, hide the route and remember only the useful shapes: a C at the front can remain until the final move, while the middle gradually becomes OO. Try rebuilding the ladder from CASH with that idea before reopening a stronger hint. If your route takes more than five changes, it may still obey the rules; compare where you introduced a temporary letter. This checked route establishes the minimum length, but does not claim to be the only possible route of that length.

The order of settled positions is second, third, fourth, then first. The intervening H-to-T change is preparation rather than a new target match. Use that distinction to explain the extra move to yourself: a necessary intermediate word can matter even when the number of matching letters does not increase. That is the central lesson of this CASH ladder.
