Spin random real stars, take one trait from each, and see how your player rates.
Ten, each with a page of its own: the NFL, the NBA, MLB, the NHL, soccer, the WNBA, college football, college basketball, the AFL and cricket. Every league keeps its own sheet of traits, so a football build is a quarterback, a baseball build is a hitter and a hockey build is a skater.
Pick a league and spin. The reel stops on a real star, and every open trait on your sheet shows the best that star ever gave it. Take one trait, spin again, and keep going until every trait is filled. One reroll per build swaps out a star you would rather pass on, and a star who could fill none of your open traits is skipped for you.
Your player lands on one fixed scale for its league, and the card ranks that number from SSS down to F: SSS from 95, SS from 90, S from 80, A from 70, B from 55, C from 40 and D from 25. Casual picks usually finish B or A and careful ones S, while an SSS needs lucky spins and sharp choices together. A 100 is the perfect arrangement of spins good enough for a 99.
No. Build a Player runs in the browser on a phone or a computer, and every build plays without signing in.
Yes. After a build, Challenge a friend copies or shares a link to your exact spins. Your friend makes their own choices, and their finish sets both players side by side, trait by trait. Share sends your finished player card instead.
