Min Uniques is a rule that forces every lineup you keep to differ from every other by at least a set number of players. Set it to 3 and any two of your lineups will always have at least three different players.
Why it matters
When you enter many lineups, near-identical copies are wasted bullets: they all win or lose together. Enforcing a uniqueness floor spreads your risk across genuinely different rosters, giving you more independent shots at a good outcome. It is one of the simplest ways to diversify a large entry pool.
Where you see it in DFS Hero
Min Uniques lives in the Lineups panel Selection menu. It applies to your working set, the lineups you fill and export, rather than the underlying pool. If the rule is too strict to reach your requested count, DFS Hero backfills the next-best lineups so you still get the number you asked for.
