Aztec Bonanza takes players deep into the jungle for a cascading reels experience with an expanding grid. Starting with a 2-4-6-4-2 setup, winning tumbles unlock corner blockers, progressively revealing more positions and ultimately creating an all-ways-win structure on a 5x6 grid. Each corner unlock also triggers unique modifiers like mystery symbols or symbol transformations, leading to a free spins round with guaranteed fully expanded reels and persistent transformations for continuous action.
