Hundreds and Thousands plays on a 5x5 grid filled with Bar and X symbols. Matching combinations award prizes, while blanks keep the tension high. Landing five Free Spins symbols on winning lines unlocks the Free Spins feature with up to 100 spins. During Free Spins, every prize is doubled with a x2 multiplier, turning each spin into a chance for amplified rewards. The number of free spins awarded depends on how many winning lines the Free Spins symbols complete.
