Gridiron

About this Slot

Gridiron is a sports-themed slot from Kelpbot Gaming with an RTP of 96%, medium volatility and a maximum win of 10,000x. The game uses 5 reels, 4 rows and 30 paylines, playing left-to-right across a classic layout. Three or more Scatter symbols trigger Free Spins, awarding 6 spins for 3 scatters, 10 for 4 and 12 for 5. During the feature, Sticky Wilds lock in place on the reels, with each wild receiving a random multiplier that can combine across the same payline to boost payouts. Free Spins can retrigger during the bonus round. Landing 2 scatters adds 3 more spins, while 3 or more scatters add 6, extending the feature and giving the sticky wild multipliers additional turns to accumulate value. Ante costs 1.25x per spin and increases the probability of landing scatters without guaranteeing the bonus, offering a modest improvement to scatter trigger chances. Blitz costs 5x per spin and guarantees a scatter symbol on every spin, providing a much faster route to triggering Free Spins for players seeking frequent bonus attempts. Mystery Bonus costs 125x per spin and instantly triggers Free Spins with up to 5 scatters revealed, potentially granting as many as 12 Free Spins immediately, bypassing base-game luck entirely.
