doublethow to play doublet

Doublet (also known as a word ladder) is a word game. You get two words, and you must transform the start word into the target word one step at a time.

Each step can change a letter, add one, take one away, or rearrange the letters you have. Every step has to be a real word.

There is no single right answer. Any valid path from the start to the end is a solution. Leaderboards count the number of steps you used, so shorter ladders are better.

the rules

head
bead
change a letter

Swap one letter for another and leave the rest alone. Head becomes bead.

hose
house
add a letter

Add a letter anywhere, keeping the others in order. Hose becomes house.

chat
cat
remove a letter

Take a letter out and close the gap. Chat becomes cat.

silent
listen
scramble

Rearrange all the letters into a different word. Silent becomes listen.

at least 3 letters

Every step must be at least 3 letters long.

no repeats

A word can appear in the ladder only once.

a worked example

Let's walk through a whole puzzle, from rain to snow, one word at a time.

  1. rain
    ???
    step 1
    snow

    We need to connect "rain" to "snow".

  2. rain
    remove "i"
    ran
    ???
    step 2
    snow

    Take the "i" out of "rain" and you get "ran".

  3. rain
    remove "i"
    ran
    ???
    step 3
    now
    add "s"
    snow

    You can build up from the bottom, too. Here we enter "now", which gets added before "snow".

  4. rain
    remove "i"
    ran
    ???
    step 4
    won
    scramble
    now
    add "s"
    snow

    We can scramble "won" to get "now". The two open ends are "ran" and "won", one word apart.

  5. rain
    remove "i"
    ran
    change "r" to "w"
    wan
    change "a" to "o"
    won
    scramble
    now
    add "s"
    snow

    We finish with "wan": one step from "ran", one step from "won". Four words added, so this scores as 4 steps. All done!

controls

Type a word into the box and press enter. A valid word joins whichever end it is one move from.

The × beside a word removes it and the steps after it. Backspace in an empty box takes you back to your last word.

tips

  • Get shorter. Three and four letter words have far more neighbors than long ones, so dropping a letter opens up more routes. You can add it back later, somewhere else.
  • Work both ends at once. You can search outward from each end and meet in the middle.
