About Unbeaten
Unbeaten is an independent sports lab: browser games and simulators built by fans who like spreadsheets as much as Sundays.
How player ratings work
Every rating in the 82-0, 17-0 and 162-0 games describes one player in one specific season, on a 0–99 scale. We start from that season's production and advanced metrics (e.g. win shares and PER in basketball, approximate value and All-Pro voting in football, WAR in baseball), then adjust editorially so different eras compare fairly. They're opinions built for a fun game, not official statistics.
How the season simulation works
Your team rating is a weighted average of your lineup. Premium positions like QB, starting pitcher and the five NBA starters count more, and players out of position lose rating. Each game draws a random opponent rating, and your win probability comes from a logistic curve on the rating gap. Games are independent, so a perfect season gets exponentially harder as the schedule gets longer.
How the NFL draft AI picks
AI teams look at the best players left on the board and score each one by grade, how well he fills a top-three team need, positional value and some randomness. Trade offers use a pick-value curve similar to the classic draft value chart.
How fantasy rankings are built
We project role, volume and efficiency for each player, convert that to PPR, half-PPR and standard points, and rank by projection. Tiers break where projected points drop off sharply. ADP shown is consensus redraft ADP.
