Symbols and Paytable in Cathedral 9

The paytable splits into low and high pays. Four pip emblems with one to four teardrops in blue, green, purple, and red cover the lows, paying about 2x to 5x for 25 or more. Premiums show a candle, a pendant, a censer, a chalice, and a golden owl statue, paying 10x to 50x for 25+. Wins count from 8 of a kind anywhere on the grid. Bonus scatters carry a golden lion head, while coffin stacks and wilds add the spice that holds runs together.

Any pay symbol can land big, at 2x2, 3x3, or 4x4. Gaps beneath a big icon fill with matching 1x1 copies. After wins stop, a big symbol may even spawn and replace others. Wilds sub for all regular pays, and an all‑wild hit pays as the top symbol. In Cathedral 9, wilds drop from the Feature Reel rather than the main set. Mystery Coffins sit as special symbols, revealing matching pays or wilds once they reach the bottom line.

Feature Reel and Core Mechanics in Cathedral 9

Cathedral 9 layers cascades with a 2x6 Feature Reel. When wins clear symbols, feature icons can drop into gaps, then a symbol drop follows. The loop repeats while wins keep coming. Three main modifiers stand out. Wild does the classic substitution job. Collect selects a paying symbol in view, then gathers every instance into one position. Explosion strips the column it lands in, along with adjacent columns. One copy is enough to fire the effect, so chains feel sharp.

Mystery Coffins are 5x1 stacks that activate when they reach the bottom. Each step, they reveal matching pays or a wild, then nudge down and do it again until no win remains. Super Mystery Coffins work the same but add their value to a global multiplier. Values can show from x2 up to x1,000. I have seen x25 land during testing; x50 and x100 seem reachable, while the top tiers look rare. Mini coffins can even spawn a new coffin above.

Entombed arrives when its symbol covers the entire Feature Reel and no more wins are present. Then all symbols on the grid change into one pay type. The Super Entombed pick uses only high or mid values. Holy Collect sits on a separate pot. A holy blocker dropping from the Feature Reel charges it, and the state carries between rounds. When it triggers, 3 to 6 coffins land on the grid. Any round holds the same chance of a trigger.

Bonus Features in Cathedral 9

Three to six bonus scatters trigger free drops. Each scatter awards 2, 3, or 4 drops, with extra scatters adding more during the round. The global multiplier is persistent between free drops, then inactivates between spins, and Coffins reaching the bottom will activate any inactive value. Win on all nine pay symbols in bonus mode to trigger the Super Bonus. You get 2, 3, or 4 extra drops, and each drop starts with 1 to 6 Super Mystery Coffins in view.

RTP, Volatility and Max Win in Cathedral 9

RTP sits at 94% and stays there even when X‑iter is used. Volatility feels 7 out of 10, with a 24.9% hit rate in the base. The cap is 25,000x the bet. X‑iter offers Bonus Hunt at 2.5x, Mega Hunt at 10x, Coffin Drop at 50x, Bonus at 100x, and Super Bonus at 500x. In my sessions, multipliers showed up as x25 a few times. x50 and x100 can pop, but x500 and x1,000 look scarce.
