Level 5 is the wall that decides your Streakle day, and the maths says so
Streakle gives you five guesses on the first word, four on the next three, and three on the fifth. We measured what that last cut costs a perfect player.
How we got these numbers
We built a greedy solver that always plays the guess minimising the expected number of surviving candidates, breaking ties toward words that could themselves be the answer. It played all 601 unique words in the live answer pool, twice per opener: once with a four guess budget and once with three. The candidate guess set was the 600 strongest openers plus every remaining live candidate at each step. Word lists were read from the shipped game source on 3 August 2026.
The rule almost nobody notices
Streakle's guess budget is not constant. Level one gives you five guesses, levels two through four give you four, and level five gives you three. The rule lives in a single line of the game's source, it is never announced with a banner, and most players discover it by losing to it.
It is also, by a wide margin, the most consequential rule in the game. We wanted to know exactly how consequential, so we built a solver that plays optimally and made it grind through the entire answer pool under both budgets.
What one fewer guess costs
Read that table again with the run rule in mind. One miss ends your day. If even flawless play fails 22 to 25 percent of three guess puzzles, then completing a run is not primarily a test of vocabulary. It is a test of how much information you extract in your first two guesses, plus luck.
This also explains a feeling most regular players have: that runs die at the last hurdle far more often than anywhere else. They do. The cliff is real and it is at level five.
| Opener | 4 guesses | 3 guesses | Drop |
|---|---|---|---|
| IRATE | 99.2% | 75.7% | 23.5 points |
| ROATE | 98.3% | 77.5% | 20.8 points |
| CRANE | 97.7% | 74.4% | 23.3 points |
| AUDIO | 97.2% | 61.4% | 35.8 points |
Solve rate is the share of the 601 answers the solver cracked inside the budget.
A perfect solver fails roughly one Streakle puzzle in four once the guess budget drops to three. A human will do worse. Level five is not a difficulty bump, it is a different game, and it is the only thing standing between you and a completed day.
Why the opener matters far more at three guesses
At four guesses, the gap between the best opener and AUDIO is about two percentage points of solve rate. Almost nothing. At three guesses the same gap is over 16 points. That is the single most useful thing in this article.
The reason is structural. With four guesses you have slack: a mediocre first guess can be repaired by a strong second and you still have two chances to convert. With three, guess one and guess two have to do all the narrowing, and there is no recovery move. A bad opener does not just cost you information, it removes your ability to survive having made it.
So if you only change one habit, change it for the end of your run, not the start. The opener you use at level one barely matters. The opener you use at level five decides whether the day is won.
How the solver actually spends its guesses
Guess three is where most puzzles are won: 63 percent of them. Guess four accounts for another 23.5 percent, and that entire slice is exactly what disappears at level five. The 141 answers the solver needed a fourth guess for are the puzzles that end runs one word from home.
Notice how few solves land on guess two. Only 12 percent of answers can be pinned down after a single opener, no matter how good the opener is. Trying to solve on guess two is almost always the wrong instinct. Spend guess two widening coverage and convert on guess three.
| Solved on guess | Answers | Share |
|---|---|---|
| 1 | 1 | 0.2% |
| 2 | 74 | 12.3% |
| 3 | 380 | 63.2% |
| 4 | 141 | 23.5% |
| Failed | 5 | 0.8% |
Playing the back half of a run
- Treat level five as a hard mode switch. Slow down. The clock is not the constraint, the guess budget is.
- Do not attempt a solve on guess two unless the surviving candidate list is genuinely down to one or two words. A speculative guess two costs you the whole run about a quarter of the time.
- Use guess two to test letters you have not touched, even if that means guessing a word you know is wrong. With three guesses this is counterintuitive and correct.
- Repeated letters are concentrated in the higher levels by design: the game's difficulty score adds 2.4 points per duplicated letter, more than any rare letter except X, J, Q and Z. If your normal approach stalls on the last word or two, test a double before you test another new consonant.
- The 15 hardest words in the pool by the game's own scoring are JAZZY, FUZZY, BUZZY, FIZZY, DIZZY, JIFFY, BOBBY, YUMMY, FLUFF, ZIPPY, PUPPY and KAYAK. Every single one has a repeat. That is not a coincidence, it is the scoring function.
Is the wall too steep?
We are publishing a number that does not flatter our own game, so it is fair to say what we make of it. A 77 percent ceiling under perfect play on the final word means even a flawless player loses about one day in four at the last hurdle, and a strong human rather more. That is a tight, high-stakes design, and it is deliberate: a finish line you clear every time is not a finish line.
It does mean the leaderboard, which counts total words solved, is measuring something closer to sustained accuracy under pressure than raw vocabulary, and we think that is the more interesting thing to measure. But if you have been feeling that your runs end abruptly and unfairly right at the end, you were reading the game correctly.
Frequently asked questions
Exactly when does Streakle drop to three guesses?
At level five, the last word of the run. Level one gives you five guesses, levels two to four give you four, and level five gives you three. Your level equals the number of words you have already solved in the current run plus one.
Does the word itself get harder as well?
Yes. Streakle sorts the whole answer pool by a difficulty score built from letter rarity, repeated letters and vowel count, then draws each of the five levels from a progressively harder band. So level five hands you both the hardest word of the day and one fewer guess than you have had all run.
Can a human realistically match the solver?
No. The solver evaluates every legal guess against every surviving candidate at each step. The useful comparison is that the solver's 77.5 percent is a ceiling, and the gap between your rate and that number is the part you can train.
What is the single highest value habit change?
Stop trying to solve on guess two. In our simulation only 12 percent of answers were pinnable after one opener, so a guess two solve attempt is usually a coin flip that costs the day.
