The niche ball knowledge game is Krillion, a free browser trivia game where the obvious answer is worth almost nothing and the rare one sinks you deeper into the ocean. The name comes from a Joe Bart Games video, "The Game Of Niche Ball Knowledge," published on October 10, 2026, and that title is what most people type into a search bar after watching it. Krillion itself is not a basketball game. Its prompts cover anything, and "ball knowledge" is sports-fan slang for knowing more than the people around you. But the idea at its heart, that a correct answer nobody else would give is worth more than a correct answer everybody would, is exactly what a basketball fan means by niche ball knowledge. This guide covers what Krillion is, how a dive plays, how it decides what counts as rare, where it stops short for NBA fans, and Deep Cut, the daily game that applies the same rule to one basketball question a day.

What the Niche Ball Knowledge Game Is
Krillion lives at krillion.io, and its home page explains itself in one line: seven prompts a day, the same for everyone, and rare answers sink you deeper. The site's tagline is "One in a krillion," and the whole presentation leans into the ocean. Your score is drawn as a depth gauge, marked on the way down with real reference points such as the Titanic's wreck at 3,800 metres.
The video that sent so many people looking for it shows the game's endless mode rather than the daily one. A fan guide to the game identifies the mode on screen as Unlimited, which Krillion's own game screen labels "The Endless Dive." Either way, the format is the same: a prompt appears, a timer runs, and you try to name something correct that the rest of the world did not think of.
It is worth being precise about the name, because the search phrase is not the game's title. "The Game Of Niche Ball Knowledge" is the video's title. Krillion is the game. Plenty of people mean basketball when they say it, and that is where an NBA version fits.
How a Krillion Dive Plays
The rules on Krillion's home page are six short lines, and they are the whole game:
- Seven prompts a day, the same for everyone.
- Twenty-five seconds to name one thing for each prompt.
- Rare answers score big. Obvious ones float.
- The pick that feels clever? The school thought of it too.
- Every point sinks you 10 metres, and 700 is the trench.
- One dive per day, with no second chances.
Do the arithmetic and a perfect dive is 70 points of depth across the day, ten metres to the point, seven hundred metres to the bottom. The game is less about how much you know than about which thing you know that others do not.
The fourth rule is the clever one. Krillion's FAQ defines a term it calls "too clever": the go-to obscure pick that is not actually that obscure. Every trivia crowd has one. Ask a room for a forgettable fact and a third of it reaches for the same forgettable fact. The game is built to punish that reflex, which is what separates it from ordinary trivia where any correct answer is as good as any other.
How Krillion Decides What Is Rare
Krillion's FAQ is open about the machinery, and it is worth reading because the scoring model is the game.
Answer sets are built by aggregating datasets, dictionaries, wiki pages and encyclopedias, whatever sources a given question calls for, then merging and cleaning the result into one list. Rarity depends on the prompt. Some can be scored mechanically against a familiarity database of how often a word or name turns up in what people read and write. Others cannot be reduced to a number like that, and those get a mix of LLM assistance and a manual pass.
The game also crowns a gem answer, the Krillion itself, and the FAQ says it is not chosen on rarity alone. Past a certain depth, rarity gets hard to tell apart, so the gem is picked partly for fun factor: the answer that is most satisfying to land on, rather than one so obscure that perhaps one player would ever type it.
The FAQ is also candid about the limits. If a fair answer is missing, the reason given is simply that the source was not found. And autocorrect is generous on purpose, because some prompts have thousands of accepted answers with aliases, which means a guess one letter off an alias can match something unexpected.
Unlimited, Themed Packs and Puffer Party
The daily dive is the front door, but the menu has more behind it. Unlimited, the mode the video shows, lets you keep diving past the day's seven prompts. Themed Packs are bundles of prompts on one subject, and the FAQ notes that any purchase, for any pack, turns ads off across the whole site. There is an archive of past dives, too. On November 10, 2026, the home page was on dive number 117.
Puffer Party is the multiplayer experiment, marked as a beta. It plays like hot potato: a puffer with a hidden fuse is passed around a room, and the FAQ explains that the fuse length is random, between 10 and 30 seconds under the default settings, shared across the room and still counting down as the puffer moves. Inherit a puffer with fewer than 8 seconds left and the timer resets to 8.
Where Krillion Falls Short for Basketball Fans
None of this is a knock on a well-made game, but a few edges are worth naming.
The first is that it is a general trivia game. The prompts span anything an encyclopedia can answer, so a basketball fan gets a sports prompt some days and none on others. The knowledge you came to show off is one category among dozens.
The second is the clock. Twenty-five seconds rewards retrieval speed as much as depth, and the deepest answers are often the ones you need a moment to dig up. A fan who knows that a draft-night trade sent a future star to another franchise may not get there before the timer does.
The third is that rarity is curated by its maker rather than defined by a single rule you can check, and the FAQ says so honestly. That is a reasonable choice for a general game. For one sport, though, there is a sharper option: score every answer against the other correct answers to the same question, from data you can verify.

Deep Cut: Niche Ball Knowledge for the NBA
Deep Cut is the daily game we built around that sharper option. One NBA question a day, five slots to fill, and the usual instinct turned upside down: the obvious answer is worth almost nothing.
Every player on the day's list carries a rarity score from 1 for the most famous to 99 for the man nobody remembers. That number is our own estimate of how well known he is, not a fan survey, and it is ranked within that question's list rather than across the whole league. On a list of MVPs, the least famous MVP is still a household name, and ranking within the list is what lets him still score well.
There is no clock and wrong guesses cost nothing, so the only real decision is how brave you are. Fill all five slots and your total is your score. Reach 150 and the day is a win, which means five obvious answers can fill every slot and still lose. Name somebody who genuinely fits the question but sits outside the scored list and he is credited as a deep cut, without filling a slot.
The questions come from the player database rather than from anyone's memory, they do not repeat within 90 days, and most of them tie a player to something: a teammate, a franchise in a bounded era, a coach, a draft. That second axis is what makes superstars unavailable as an easy way out.
A Real Deep Cut Board: Players Drafted by the Denver Nuggets
The clearest way to see the game is one real board. On November 1, 2026, Deep Cut asked for players drafted by the Denver Nuggets. The scored list held 28 names, and 55 more correct answers sat outside it as deep cuts.
The top of the board is what you would expect. Nikola Jokic scored 1. Carmelo Anthony scored 5. Dikembe Mutombo scored 8. Then two names that make the point of the whole game: Donovan Mitchell, also at 8, and Rudy Gobert at 16. Denver drafted Mitchell 13th overall in 2017 and traded his rights to Utah for Trey Lyles and the draft rights to Tyler Lydon. Denver took Gobert 27th in 2013 and sent him to Utah for the 46th pick, Erick Green, and cash. Both still score low, because the scale measures how famous a player is, not how surprising the connection is. Fame is the thing being priced.
Add up the five most obvious answers and you get 38. The bar is 150.
The deep end is where the board pays. Ryan Dunn scored 99: Denver took him 28th in 2024 and traded his rights to Phoenix on draft night. Eleven names sat at 59, among them Jalen Rose, whom Denver drafted 13th overall in 1994; Kenneth Faried, the 22nd pick in 2011 out of Morehead State; Mahmoud Abdul-Rauf, drafted 3rd overall in 1990 out of LSU as Chris Jackson before changing his name in 1993; and Tyronn Lue, whose draft rights Denver sent to the Lakers with Tony Battie for Nick Van Exel on June 24, 1998. Doug McDermott sat at 41, a reminder that Denver drafted him 11th in 2014 and moved him to Chicago, with Anthony Randolph, for the picks that became Jusuf Nurkic and Gary Harris.
Five answers from that deep end, one 99 and four 59s, total 335. The difference between 38 and 335 is the entire game, and it is made of draft nights.
Crowd Favourite: The Same Model, Right Way Up
Crowd Favourite is Deep Cut's mirror. It shares the same scoring model, used the right way up, so the two games can never disagree about which players are obvious, and the generator guarantees they never ask the same question on the same day.
Here the board is a list of hidden answers ranked from best known to least obvious, and the job is to reveal them. You have three lives. A name that is not on the board costs one, but naming somebody you have already found costs nothing, because losing track of a board in front of you is not the skill being tested. Reveal half the board and the day is a win.
Shot Clock and Hoop Grid: Rarity Against the Clock and the Crowd
If what hooked you in Krillion was the timer, Shot Clock is the nearest daily cousin. One question, a list of correct answers, and a clock that starts at 100 seconds or more, scaled to the size of the list. Every correct answer adds five seconds, a wrong one costs nothing, and the bank caps at 180 seconds. Correct answers that sit below the pool's recognisability bar are still accepted and still earn their five seconds, so a genuinely deep name is never called wrong.
If what hooked you was being the only one to say it, Hoop Grid scores exactly that. It is a three-by-three board where every cell crosses a row with a column, teams against teams, awards or career stats. You get nine guesses, fill six cells to win, and every pick is scored against everyone playing that day. A pick nobody else made is a unicorn. Where Deep Cut prices fame from a model, Hoop Grid prices rarity from the crowd itself.
Krillion and Deep Cut, Side by Side
- The subject. Krillion asks about anything. Deep Cut asks one NBA question a day.
- The clock. Krillion gives 25 seconds per prompt. Deep Cut has no clock at all, and Shot Clock is there for the timed version.
- The number of tries. Krillion takes one answer per prompt. Deep Cut lets you keep guessing until five slots are full, and a wrong guess costs nothing.
- How rarity is set. Krillion blends a familiarity database, LLM assistance and a manual pass, and picks its gem partly for fun. Deep Cut ranks each answer's recognisability within that question's own list, from 1 to 99.
- The shared puzzle. Both give everyone the same daily set, which is what makes a score worth comparing.
How to Find a Deep Cut
The tips that win Deep Cut rounds are the same instincts that make a Krillion dive go deep, sharpened for one sport.
Skip your first three thoughts. The names that arrive instantly are the ones scored lowest, by definition, and on the Denver board that was Jokic, Anthony and Mutombo.
Think about the edges of the criterion. The man who only just qualifies is the one nobody else names. On a "drafted by" question the edge is the draft-night trade, the player whose rights were moved before he ever wore the jersey. Dunn, Lue, McDermott, Mitchell and Gobert all came off that one edge.
Remember that role players who lasted are gold. Longevity puts a player on a list without making him famous, and that combination is exactly what the scale rewards.
And since wrong guesses are free, a half-remembered name is always worth typing.
