Ball Knowledge
A free daily sports gaming platform for NFL, NBA, MLB, and NHL fans.
Ball Knowledge gives sports fans something to do every single day. Six daily games reset at midnight ET across all four major North American sports leagues. Come back every day, build your streak, earn XP, and see where you rank on the weekly and all-time leaderboards.
Beyond the daily games, there are seven multiplayer party games designed to be played in a group on a single device — no extra accounts, no extra devices needed. The platform is free to use. Create an account to save your progress, or play without signing up.
Daily Games
Six games. Every day. Midnight reset.
All six daily games reset at midnight ET. Your streak increments each day you play. Each game awards XP based on your performance — higher skill rewards more XP.
Mystery Player
One hidden active player per league per day. Guess by typing any player name and receive color-coded attribute feedback: team, position, age, height, college, draft round, and years pro. Green is an exact match. Yellow is close, with a directional arrow on numeric attributes. Gray is wrong. Maximum 8 guesses to identify the player through deduction. Generates a spoiler-free emoji share grid on completion. Available for NFL, NBA, MLB, and NHL.
Blind Showdown
Two players side by side with only their statistics visible — no name, no team. Pick the statistically superior player before the identity reveal. Matchups are curated to challenge assumptions: a lesser-known player outproducing a household name, or a former award winner compared against a rising challenger. After you pick, the players' identities are revealed along with how the rest of the community voted.
Blind Rank 5
Five players from the same league revealed one at a time with full identity visible — name, team, position, and key stats. Before the next player appears, place the current player in one of five numbered slots. Once placed, that slot is locked permanently — no rearranging. After all five placements, see the community distribution: what percentage of all players ranked each person in each slot.
Sports Trivia
Three questions per league in ascending difficulty — Easy, Medium, and Ball Knowledge. The Ball Knowledge difficulty tier separates fans who watch games from fans who study the sport. A count-up timer runs from your first question to your final answer, and personal bests are tracked per league.
Power Play
A fast-money style daily challenge. Answer rapid-fire sports questions and hit the target score before you run out of attempts. Rewards both speed and sports knowledge breadth. New questions every day.
Auto Complete
Fill in the sports search results. You're shown the start of a sports-related search query and must predict how real fans complete it. Tests sports pop culture knowledge as much as pure stats knowledge. New prompts daily.
Multiplayer Games
Seven party games. One device. No internet required.
All multiplayer games are pass-and-play on a single device. No extra accounts needed. No internet required during gameplay.
Sports Imposter
Social deduction game for 3–10 players. Most players receive a real athlete's career profile — stats, highlights, team history. One or two impostors receive nothing and must bluff through the discussion phase. Pass the phone around for role reveals, then discuss and vote out who you think is faking. Difficulty settings range from casual to Ball Knowledge tier. Expansion packs available for legends and historical players.
Sports Wavelength
A spectrum guessing game for 2+ players. A semicircle arc is displayed with opposing sports concepts at each end — like "Role Player ↔ Franchise Player" or "Clutch ↔ Choke Artist." The clue giver sees a hidden target on the spectrum and gives a sports-only clue pointing to where it falls. Guessers place needles on the arc. Points are awarded based on proximity to the hidden target. Rotating clue giver each round.
Draft With Friends
A snake draft for 2–8 players with a randomly revealed category: "Best Lakers of All Time," "Athletes You'd Want on Your Pickup Basketball Team," "Most Entertaining Players to Watch." Take turns drafting whoever fits. Free text input — no validation, no wrong answers. The completed board is shareable as a branded image. Completed drafts are saved so you can revisit past boards.
Who Am I?
Each player has an athlete secretly assigned to them — visible to everyone else but not themselves. Ask yes/no questions to figure out who you are before anyone else does. The classic social guessing game adapted for sports fans.
13 Words or Less
Describe a player, team, era, or sports moment using 13 words or fewer. Fast, creative, and harder than it sounds — especially for obscure matchups or historical moments. Other players guess what you're describing.
Custom Mystery Player
Create a custom Mystery Player challenge by choosing any player and generating a shareable code. Friends use the code to play the same guess-the-player experience as the daily game — but you chose who they're guessing. Good for group chats and sports debates.
Progression
XP, levels, streaks, and leaderboards.
Every game you play earns XP. Daily games award a base amount plus performance bonuses — solve the Mystery Player in fewer guesses, get trivia right, or nail your Showdown picks for extra XP. Multiplayer games also award XP per round played.
There are 15 levels, starting at Rookie and ending at Ball Knowledge. Your lifetime XP determines your level. Weekly XP resets every Monday and drives the weekly leaderboard — which means the rankings stay competitive even for newer players.
The leaderboard has three tabs: Weekly (resets every Monday), All Time (lifetime XP ranking), and Friends (see where you rank among people you've added). The top three players on each leaderboard appear on a podium with their XP and current streak.
