Prove You Kno Ball

About iKnoBall

iKnoBall is an all-time sports draft game. A slot machine deals you a franchise and a decade, you draft one legend from that roster, and you repeat across every era until you have a full team. Then you pick your starters and simulate a season. Your record depends on the players you chose — nothing else.

It covers five sports: the NBA, NFL, Premier League, NHL and MLB. You can play free in your browser at play.iknoball.com or on iPhone through the App Store.

How players are rated

Every rating comes from real career production — per-game output, efficiency and peak seasons — scaled so players from different eras can be compared on the same curve. The season simulation only uses your starters, and an undefeated season takes an almost perfect lineup.

Who builds it

Before anything else, I was a sports kid. I grew up playing sports, and when the pro games would wrap up, I’d be up checking stats and talking ball long after I should have gone to sleep. iKnoBall is my love letter to that 13-year-old. I built it for him, and for everyone like him who still wants to prove they know ball.

iKnoBall started as an NBA-only draft and grew into five sports, daily challenges, head-to-head drafts, private leagues and The Slate, a weekly NFL fantasy draft scored on live stats.
