The basics
You begin with a four letter starter word that is the same for everyone. Each move changes exactly one letter and has to produce a valid word.
There is no guess limit in the usual sense. The number you are competing on is how many moves your route took.
Work from both ends
The most useful habit is to solve backwards as well as forwards. Look at the target and write down the words that are one letter away from it. Then do the same from your starter.
Most ladders are solved when those two lists meet in the middle, and finding the meeting point is much faster than pushing blindly forward.
Vowels are your bridges
Words with common vowel patterns connect to far more neighbours than words with awkward letter combinations. If a route stalls, it is usually because you have moved into a corner of the dictionary with few exits.
When you have a choice, prefer the move that keeps your word flexible even if it does not obviously get you closer.
A worked ladder
Suppose you need to reach a target ending in double S. Rather than fixing the first letter and hoping, start by listing the words one step from the target. That gives you a small set of landing pads.
Now look at your starter and ask which of those landing pads you could plausibly reach in two or three moves. Aiming at a specific landing pad turns a vague search into a short, concrete route.
Tips worth remembering
- Write the target's neighbours down first. It turns the puzzle around.
- Do not protect a matching letter if changing it opens a much better bridge.
- Short is not always obvious. The first route you find is rarely the shortest one.
- If you are stuck for more than a minute, reset and try a different second move rather than grinding.
