About Build a 99
Updated November 13, 2026
A football decision game
Build a 99 asks a simple question: which single skill would you take from a player if you had to build someone new? A run combines seven traits from franchise pools, then simulates the career of the player you assembled. The challenge comes from choosing which skills to secure early and which to leave for a later spin.
What we make
The project combines original game rules, a positional scoring model, curated player pools and fictional career reports. All-Time ratings express the game’s own judgments. Current ratings use a documented source model with game-specific adjustments. The strategy and scoring guides explain how those decisions affect play.
