Secret Symbol Slot by RealTime Gaming

The Chief is the whole point of this one. He sits on the reels as a premium character - a tribal figure in feathered dress - and once the Free Games Feature kicks in he stops behaving like a regular paying symbol. Every Chief that lands during free spins transforms into a Wild on the spot, with a transition sound that RTG reused in a handful of its mid-2010s titles. A feature multiplier runs alongside the transitions, scaling up as the round extends, so a Chief that turned wild on spin one can end up sitting inside a 3x or 5x prize by the back half of the bonus. It's the same chain reaction that keeps players chasing scatters in the first place.

Three or more stone-carving scatters trigger the bonus, and the free-games layer itself runs on three tiers. The base tier hands out the standard free spin package. Landing additional scatters during the round pushes you into higher tiers with better multiplier progression - RTG's asset files still carry FreeGames1, FreeGames2, and FreeGames3 labels, and the tier you end up in changes how aggressively the Chief transitions pay. A retrigger during the round adds more spins without resetting the tier, so the longer you stay in, the more Chief conversions compound against the scaling multiplier.

There's a Priestess symbol that sits alongside the Chief at the premium end, paying enhanced values specifically inside free games rather than the base round. The Pyramid and the Secret Symbol logo round out the high-tier icons, with the logo pulling double duty as the Wild - it substitutes for everything except the scatter and appears across all five reels. Low pays run the standard A/K/Q/J/10/9 deck but redrawn with Mayan-style carving borders to match the setting.

The Major progressive ticks above the reels. It drops randomly after any real-money spin regardless of bet size, seeded from the shared RTG network, which means the jackpot has no relationship to your stake or the bonus round - it just hits when it hits. On the RTG side this sits in the same progressive pool as Asgard and Cash Bandits 2, and during testing the meter was parked in the low four figures.

Visually the reels sit inside a dense jungle frame with a waterfall on one side and vines creeping across the borders, and the symbols lean toward carved trinkets, clay pots, and feathered tribal accessories rather than clean Mayan glyph work. A panther portrait and a parrot pair show up as mid-tier symbols, which gives the set a more South American rainforest feel than the pure temple-interior theme the title might suggest. The 10,000x ceiling realistically opens up through a Tier 3 bonus run with multiple Chief transitions stacking inside a maxed-out multiplier, which doesn't come often but is the reason this one still gets played nine years after release.
