In poker, a freeroll tournament is a tournament with no entry fee, and a freeroll hand is where a player is guaranteed to at least split the pot with his opponent, with a chance they can win the whole pot if certain final cards are dealt.

A hand in which a player is guaranteed to at least split the pot with his/her opponent, with a chance to win the pot outright. For example, if you have A&` A&c and your opponent has A&e A&f, and the board comes 8&`9&`2&fQ&`, you're freerolling the ability to win the whole pot with a made flush if a spade hits on the river.
