Stringle strategy guide

Just four letters can allow you to travel through thousands of words! In Stringle, you connect a starting word to the target by changing just one letter per move. Every step must be a word accepted by the game’s dictionary.

Finding a correct solution is the first challenge, but finding the shortest solution gives you something to work toward.

Finding your first word

Look at each position in the starting word and try changing it. You don’t have to type every possibility; just think through a few familiar words first.

For example, from COLD, you can notice CORD or GOLD or SOLD. Each changes exactly one letter. You don’t need to try out every possibility; think through a few familiar words first and choose whichever one looks closest to the target word!

If nothing comes to mind, that’s no problem. Work through the positions in order. Try replacing just the first letter; see if you can come up with something. If not, try the second or the third and so on. This gives your search some structure instead of leaving you staring at the starting word.

Working towards the target

A letter that matches the target can be useful, but it doesn’t guarantee that it’s the optimal solution. Sometimes you need to change a matching letter temporarily to reach a word with better connections. Treat the marked tiles as useful information rather than letters you must protect.

Also, it’s very useful to think backwards. Ask yourself which words can come right before the target and work towards that. You still enter the string from the starting word, but imagining the final steps can reveal connections you hadn’t considered.

Here’s a worked string: COLD to WARM

COLD → CORD → CARD → WARD → WARM

Here’s what changes:

That totals four moves. The starting word doesn’t count as a move.

For this, four moves is the shortest possible solution. COLD and WARM differ in every position, so reaching WARM needs a minimum of four letter changes. This string reaches it in exactly four.

Knowing the lower bound is helpful, but sometimes reaching it is not possible. Some pairs need extra steps because direct letter changes can’t form accepted words.

When you get stuck

Try looking for a different connection rather than repeatedly testing small variations of a dead end.

What not to do for COLD to WARM:

COLD
MOLD
TOLD
BOLD

Notice how you keep changing the same position without making progress towards the target. These words aren’t necessarily dead ends, but continuing this way without finding another connection adds moves.

You can come back to older words, but you must reach them through valid one-letter changes from your current position. For example:

If you want to get back to PALE:

PALE
MALE
TALE
GALE
TALE
PALE

Now you return to PALE.

However, every step backwards counts towards your total moves. Entering the same word twice in a row is not allowed.

If you are really stuck, you can use hints. Hints reveal a valid next word on a shortest route from your current word to the target. You still need to submit that word, so it counts towards your move total.

Occasionally, a word you know won’t be accepted. Stringle uses its own game dictionary, so acceptance depends entirely on that list.

Daily and Endless

Daily gives you one puzzle for each calendar date, changing at midnight in your timezone. Finishing the Daily counts towards your daily streak. At the end of the Daily, your score is compared with other submitted results for that puzzle.

Endless is a place to keep experimenting. You can start another puzzle whenever you want, or reset the current one to try a different approach from the same starting word.

After finishing, compare your moves with the optimal count. If you used more moves, you can check out the optimal path and find connections you can use next time.

You don’t need to find the shortest string immediately. Start by finding a route, figure out where it took a detour, and carry that idea to the next puzzle.

A useful strategy

If you are getting from COLD to SOUR:

Try applying what I call the vowel strategy. Notice how the two vowels in the final word are in the second and third positions. A decent strategy is to try and convert COLD to any word that also has vowels in the same positions. This can make it easier to continue and progress. Here’s how it looks:

COLD → FOLD
FOLD → FOOD

I couldn’t change COLD directly to FOOD because that would change two letters, so I used FOLD to get to FOOD. From there, we can:

FOOD → FOOL
FOOL → FOUL
FOUL → SOUL
SOUL → SOUR

Getting to a word that has the same vowel positions can be extremely helpful, although it doesn’t guarantee the shortest solution.
