NBA Quiz

How the quiz works

Press start and you get a round of 10 multiple-choice questions. Click an answer — or press 1, 2, 3 or 4 on your keyboard — and the right answer lights up straight away, with a one-line explanation of the fact behind it. Get a run going and a streak counter appears; miss one and it resets, so a clean sheet is worth chasing.

There's an optional 15-second timer per question. Leave it off for a relaxed round of NBA trivia, or switch it on and the quiz turns into a reaction test where hesitating costs you the point. At the end you get your score, your best streak, your personal best for that difficulty, and a full review of every question with the correct answer next to whatever you picked. Nothing is uploaded — scores live in your own browser.

Seven kinds of question

Every question is assembled from a field that actually exists in the roster data, which is why the quiz can go forever without repeating itself:

• Which team does this player play for? — four club logos, usually from the same conference so the easy half-answer is off the table.
• Who is taller? — two players head to head, with a gap small enough that you have to know rather than guess.
• Which of these players went to Duke? — one college, four players, one alum.
• What jersey number does he wear? — four real numbers from around the league, three of them close to the right one.
• Which player is the oldest? — four faces, ages computed from real birth dates, so the answer is right today and still right in six months.
• Which of these is listed as a Center? — position spotting, with decoys picked at a similar height so the silhouettes don't give it away.
• Which player was born outside the United States? — the international game, one birthplace at a time.

The distractors are chosen deliberately, not at random: same conference, similar height, neighbouring jersey numbers. A basketball guessing game is only fun when the wrong answers are believable.

Casual, Ball Knower or Deep Bench

The difficulty selector changes who the quiz asks about, not how the questions are phrased.

Casual sticks to household names — All-Stars and the faces you'd see on a national broadcast. Ball Knower opens it up to the rest of the rotation: solid starters, sixth men, the players you only know if you actually watch games. Deep Bench is the entire league, two-way contracts and end-of-roster prospects included. That last one is genuinely hard, and it's meant to be.

Your choice is remembered, and each difficulty keeps its own personal best, so a 10/10 on Casual doesn't quietly overwrite a hard-earned 7/10 on Deep Bench.

Tips for scoring 10/10

Learn the divisions, not just the teams. Team questions pull their decoys from the same conference, so knowing that a player is "out West" won't save you — you need the club.

Use listed height as a tell. On position questions the decoys are height-matched on purpose, but listed height and listed position still correlate: a 6'2" player is almost never the Center in the group.

Remember draft pedigree. College questions favour the programs that send the most players to the league, so Kentucky, Duke, UCLA, Kansas and UConn come up often — learning a dozen alumni from each pays off fast.

Play the timer off first. Take a few untimed rounds to learn how the questions read, then switch the clock on when you want the score to mean something.

NBA trivia that doesn't go stale

Most basketball trivia games are a fixed list somebody typed out once. Ours isn't: the questions are built at the moment you press start, from the same player file that powers our daily guessing game. When a player is traded, the team question about him changes with the next data refresh. Ages are calculated from birth dates every time you load the page rather than baked in, so nobody is stuck at the age they were when the file was written.

That also means there is nothing to run out of. Play ten rounds in a row and you'll see different players, different teams and a different mix of question types every time — a proper endless basketball guessing game rather than a quiz you finish once.
