In depth
A freeroll refers to either a poker tournament with no entry fee, allowing players to compete without financial risk, or a scenario where a player cannot lose but retains the opportunity to win additional chips. This term encompasses both risk-free tournament participation and strategic situations where downside is eliminated while upside potential remains.
