Aztec Blaze by Pragmatic Play.

Colossal symbols will have you feeling the burn in Aztec Blaze™! Played across 6×4 reels Aztec Blaze™’s symbols depict numerous beasts which must form matching combinations across the title’s 25 paylines to award a win.

Colossal symbols can randomly trigger and change the reel sizes beginning at 2×2, they grow for each win gained containing the colossal symbol up to 4×4 at which point additional wins gained with the colossal symbol gain an increasing multiplier of up to 10x.

The free spins round is triggered for landing two scatters and plays like the colossal symbol feature, with 5 lives being gained initially and these reducing each time a spin that doesn’t create a win inclusive of the colossal symbol occurs.

This allows additional opportunities to grow the colossal symbol and increase its multiplier throughout the free spins round!
