Chan's Treasure Slot by BigPot Gaming

Cascading wins leave behind Golden Squares. That one sentence is the entire foundation here - every cluster of five or more matching symbols that clears off the grid marks those positions gold, and the squares stick around through the full cascade chain. Once the tumbling stops and no new clusters form, a gorilla named Chan can appear and slam the reels, converting all accumulated Golden Squares into prize symbols: bronze, silver, and gold coins carrying multipliers from 0.2x up to 500x.

But the coins are just the starting layer. After they land, Magic Skulls activate. Ruby Skulls multiply adjacent coin values by up to x20. Diamond Skulls do the same thing but hit every coin on the grid at once, not just neighbors. Then Holy Grails absorb the multiplied coin values around them, stacking everything into a single massive payout per grail. And here is where it loops - after the grails finish absorbing, the Golden Squares reactivate and spawn a fresh round of coins, skulls, and grails. The cycle keeps going until no new symbols generate. It is a cluster pays game that plays more like a hold-and-win feature bolted onto a tumble engine.

For 100x your bet, the buy bonus drops 4 to 6 scatters and puts you straight into free spins. The free spin round uses the same mechanics, but Golden Squares carry over between spins instead of resetting. Ten spins with persistent Golden Squares building across every cascade means the quake feature fires on a much larger grid of marked positions than you will ever see in base play. Retriggers add 3 to 8 extra spins depending on scatter count. Four fixed jackpot tiers - Mini at 10x, Minor at 100x, Major at 1,000x, Mega at 10,000x - also drop from Golden Squares during the quake, separate from the coin and grail system.

Stone carved symbols sit against a Mesoamerican temple backdrop flanked by flaming torches. High pays are ornate golden masks. The lows are teal-and-gold card values etched into stone tiles. Chan himself stands to the left of the grid, gold chains and wristbands catching torchlight. Visually it leans hard into the jungle ruin aesthetic, and the earthy brown and green palette works. The mechanic layering is dense for a mid-volatility game from a smaller provider - most sessions will run through standard clusters without triggering the quake, but when it fires, the coin-skull-grail chain has real depth to it.
