You’re sitting there with a pen—or maybe your thumb is hovering over a smartphone screen—and you’ve got three letters left. The clue says "pool problem," and your brain immediately goes to expensive stuff. You think of a cracked liner. You think of a broken pump. Maybe you're thinking about those gross green algae blooms that happen when you forget the chlorine for a week. But in the world of the New York Times, LA Times, or USA Today crosswords, "pool problem" almost never refers to your backyard maintenance nightmare.
It's usually ALGAE. Or maybe LEAK.
Crosswords are a weird game of mental gymnastics. They don't want the literal answer most of the time; they want the "crosswordese" answer. If you've been staring at a grid for twenty minutes wondering why "PH balance" doesn't fit into a four-letter slot, you aren't alone. Solving these is less about knowing everything and more about learning how a constructor’s mind works. Honestly, it's a bit of a secret language. Once you speak it, you'll see the same patterns everywhere.
Why Pool Problem Crossword Clue Pops Up So Often
Constructors love certain words. In the industry, we call them "vowel-heavy gems." Think about the word ALGAE. It has three vowels and two very common consonants. It’s a dream for someone trying to fill a corner of a grid where the "A" needs to start a word like "AORTA" and the "E" needs to end a word like "SNEE."
That’s why you see it constantly.
But "pool problem" is a broad umbrella. Depending on the day of the week—and crosswords get significantly harder as the week progresses from Monday to Saturday—the answer changes. On a Monday, you’re looking for something simple like LEAK. It’s direct. It’s three or four letters. It makes sense. By the time Friday rolls around, the constructor might be getting cheeky. They might be referring to a billiards pool problem, like a SCRATCH or a SNOCKER (though that's more of a UK thing).
The Most Common Answers You'll See
If you're stuck right now, try these on for size. ALGAE is the heavyweight champion. It appears in the NYT Crossword hundreds of times. If the clue is five letters, start there. It’s almost always the culprit. If the slot is four letters long, try LEAK.

Sometimes, they get literal with the location. SCUM is a frequent flier. It’s a bit derogatory for a nice swimming hole, but it fits the grid. If the clue is something like "Pool problem for a pro," and it's seven letters, you might be looking at SCRATCH. This is where the "pool" part refers to the game of billiards, not the thing you jump into. This is a classic crossword misdirection. They want you thinking about chlorine and swimsuits when you should be thinking about felt tables and cues.
Decoding the Constructor's Intent
Will Shortz, the legendary editor of the NYT Crossword, is famous for these kinds of "aha!" moments. A "pool problem" could even be a CLOG. Think about the filter. If you have a three-letter space, it could be PHS. As in, the PH level is off. It’s a bit of a stretch, and purists hate pluralizing things that shouldn't be plural, but in the heat of a difficult Saturday puzzle, anything goes.
Actually, let's talk about the billiards angle more.
If you see "pool problem" and the answer is KISS, don't panic. In billiards, a "kiss" is when two balls touch unintentionally, ruining your shot. It’s a problem. It’s in a pool game. Ergo, it’s a "pool problem." This is the kind of lateral thinking that separates the casual Sunday morning solvers from the people who compete in the American Crossword Puzzle Tournament in Stamford.
When the Problem Isn't Physical
What if the "pool" isn't water or a game? What if it's a pool of people?
A STRIKE can be a problem for a typing pool (if we’re using old-school terminology). A DRY SPELL could be a problem for a betting pool. This is where the complexity of the English language becomes a weapon for the person who wrote the puzzle. They are looking for the "third or fourth meaning" of the word.

- Physical Pool: Algae, Leak, Scum, Clog, Scale.
- Billiards Pool: Scratch, Hook, Snooker, Bad break.
- Resource Pool: Shortage, Deficit, Drain.
You have to look at the surrounding words. If you have the "L" from "ALGAE," but the rest of the word doesn't fit, check your "downs." Crosswords are a self-correcting mechanism. If one word is wrong, the whole section collapses like a house of cards.
Expert Tips for Breaking Through the Gridlock
I've spent years staring at these black-and-white squares. The biggest mistake people make is getting married to their first guess. You put down "ALGAE" and you refuse to move it. But maybe the answer was SLIME. They both have five letters. They both start with a letter that could work with a down-clue.
When you're stuck on a "pool problem" clue, try "penciling" it in mentally. Look at the letters it provides for the intersecting words. If those intersecting words start to look like gibberish—words that start with "QX" or "ZJ"—your "pool problem" answer is definitely wrong.
Another trick? Look for the question mark. In the crossword world, a question mark at the end of a clue is a giant neon sign saying, "I am lying to you!" If the clue is "Pool problem?" with that little hook at the end, it is almost certainly a pun. It won't be algae. It’ll be something like NO DIVING or CARPOOL.
The Evolution of Crosswordese
Back in the day, clues were very literal. You’d see "A green plant in water" for ALGAE. But modern puzzles, especially those edited by younger, hip editors like David Steinberg or Patti Varol, like to play with cultural references. A "pool problem" today could easily be a reference to DEADPOOL, the Marvel character. Maybe his "problem" is his SCAR or his MOUTH.
It sounds crazy, but that’s the evolution of the game. It’s no longer just a vocabulary test; it’s a pop culture trivia night mixed with a linguistics degree.

If you're using a digital app like the NYT Games app, don't be afraid to use the "Check Square" feature if you're really losing your mind. There is no shame in it. We all do it. Even the pros have days where their brain just won't click into the right gear. Crosswords are supposed to be a workout for your brain, not a source of high blood pressure.
Real-World Examples from Recent Puzzles
Just last year, a major puzzle used "Pool problem" to lead to the answer EVAPORATION. That’s eleven letters! It’s a literal problem—the water is disappearing—but it’s not the first thing you’d think of. You’d be looking for "leak" or "crack."
Then there was the clue "Pool problems" (plural). The answer was MISCUES. This points back to the billiards table. Notice the pluralization. If the clue is plural, the answer MUST be plural. If it says "Pool problems," and you're trying to fit ALGAE, you’re going to be one letter short unless you make it ALGAES, which is rare but does happen in some of the more "experimental" grids.
Moving Forward with Your Solve
Next time you see this clue, don't just jump to the first thing that comes to mind. Count the boxes. Check for the question mark. Think about the three types of pools: the swimming kind, the gambling/resource kind, and the billiards kind.
- Check the length: 4 letters is often LEAK, 5 is usually ALGAE.
- Look for puns: If there's a question mark, think about CARPOOL or POOL SHARK.
- Verify the intersections: Don't let a wrong guess ruin the whole quadrant.
- Consider the day: Monday is easy/literal; Saturday is a psychological war zone.
Start by filling in the "gimme" clues around the "pool problem" slot. Usually, the "downs" will give you a vowel or a common consonant that eliminates half of your possibilities. If you get a "G," you're probably looking at ALGAE or CLOG. If you get a "K," it’s almost certainly LEAK or SCRATCH.
Keep your eraser handy. Crossword solving is a process of elimination, not a test of pure intuition. You’re essentially decrypting a code that someone else wrote to intentionally mislead you. Take it slow, look at the grid from a distance, and eventually, the answer will reveal itself. You've got this.
