Full explanation — Blinds
Blinds refer to the mandatory bets posted by the two players to the left of the dealer button before any cards are dealt in a poker hand. These forced contributions, consisting of the Small Blind and Big Blind, serve to create an initial pot that players will compete for. Their primary purpose is to ensure there's always an incentive to play a hand and to prevent players from simply folding every hand without consequence, thus maintaining game flow and action. Without blinds, there would be no immediate cost to folding, leading to extremely tight and unplayable games.
