The pay structure is a strange hybrid. It's called cluster pays, but the trigger reads more like a ways rule. You need at least three matching symbols connected, the chain has to start on reel 1, and it must reach reel 3 to count. Once it lands, winners stay put and the rest get cleared. Fresh symbols drop into the gaps, and each new drop only sticks if it connects on adjacent reels to the existing cluster. The chain ends when nothing new sticks, and the payout is the number of collected symbols multiplied by that symbol's value. Bonus icons sit out of the math entirely.
The Colossal Symbol layer is where the variance shows up. During any free drop a 2×2 or 3×3 oversized block can land, each carrying a multiplier from x4 to x500. A symbol with a multiplier counts as multiple symbols rather than one, so a 3×3 block painted x100 pays as nine icons at one hundred times the value. If the block leaves empty cells underneath, Wilds fill them. Regular Wilds substitute for everything except the Bonus and inherit whatever multiplier the symbol they're standing in for is carrying.
Three Bonus symbols award 10 free spins. Each extra Bonus on the trigger adds +3, and any Bonus landing inside the round adds +1. The opening dice roll sets the variance tone, deciding two things at once. The starting value of the Vine Multiplier, and whether each future row fill raises it by x1, x2 or x3. A high roll on both axes leaves the meter at a healthy base that's also climbing fast every row. A low roll keeps things grounded for the whole feature. Symbol Upgrade fires on the same row-fill trigger: collected symbols bump one tier toward the premium end of the paytable, and the highest-paying one gets an extra multiplier. The direct buy costs only -2% off the base return, unusually cheap. Honestly though, the dice roll can ruin a buy before the first spin lands, which is the trade-off you sign up for.
The reels sit between two enormous Mayan stone idol guardians, weathered grey statues with carved eyes on both sides of the grid. Leafy vines crawl across the borders, and the background is a foggy jungle of ferns and mossy pre-Columbian ruins. Mid-pays are colored mask tiki idols in orange, blue, green and yellow, with the orange demon mask at the top of the paytable. Lows are A K Q J carved into the same stone-tablet style with red, blue, green and orange gem accents. A May 2020 release, sitting in the studio's experimental labs branch.
