Roster building games: the complete guide
A roster building game gives you real players — often from every era of a sport's history — and one job: assemble the best possible team. Unlike season-long fantasy sports, the payoff is immediate. You draft, the game simulates, and you find out in minutes whether the team you built could have gone undefeated.
How roster building games work
The heart of the genre is constrained drafting. If you could pick anyone, everyone would build the same team — so a good roster builder limits your options each pick and makes you optimize. In 20-0, a spin lands on a team and a roughly five-year era; you draft one player from that pool into an open position slot, then spin again. Twelve picks later you have a full roster across offense and defense, and a season simulation projects your record. The perfect run — 17 regular-season wins plus 3 in the playoffs — is the 20-0 the game is named for.
Skill shows up fast: balancing your weakest starter against your stars, knowing which positions are scarce, spending limited re-rolls at the right moments, and recognizing the best season of a player's career when it spins up. Our perfect-roster strategy guide breaks the decision-making down.

More than solo play
Every game shares a daily challenge — the same spins for everyone, once per day, with a global leaderboard and streaks, like a Wordle for sports fans (more on that here). Beyond the daily there are head-to-head seed duels with friends, casual pools, ranked ladders with divisions, and hourly tournaments with prize brackets.
Frequently asked questions
What is a roster building game?
A roster building game hands you a pool of real players and challenges you to assemble the strongest possible team under constraints — a budget, a draft, or in 20-0’s case, a spin that decides which team and era you can pick from each round. Your finished roster is then scored or simulated, so every pick matters.
How is a roster building game different from fantasy football?
Season-long fantasy football scores your roster with weeks of real-world box scores. A roster builder gives you the same draft-day decision-making but resolves instantly: draft your team in a few minutes, simulate the season, get your record, play again.
