Skull Gates is Glass Cannon’s six-reel gothic slot from August 2026, where up to 4,096 ways pay as symbols cascade and soul-orbs multiply every winning spin. In the free spins those orb values pile into a multiplier that never resets, which is how the game reaches its 50,000x cap at a 96.70% RTP. Rated high volatility, it suits players who are happy to wait for a bonus round that keeps compounding.

Dropping symbols across 4,096 ways

The grid is six reels of four rows. A symbol pays when it lands on three or more adjacent reels from the left, and the winning symbols then vanish while fresh ones drop down to replace them, chaining wins until nothing else connects. The paytable on its own is modest, with the top symbol returning 6x the bet for six of a kind across all six reels, so the real money in this game comes from the multipliers.

Two wilds help those chains along:

  • Bone Wild: fills a single position.
  • Demon Wild: covers a 2×2 block of four positions.

Both are placed on the board before the symbols drop, and neither carries a multiplier or stands in for a Skull Gate.

Collecting soul-orbs after each win

The soul-orb is the whole multiplier system in one symbol. Each orb carries a value from 5x to 1,000x, with blue orbs below 20x and red orbs at 20x and above, so the colour tells you roughly what has landed. A win does not remove an orb, so each one waits on the board to be collected.

When a spin with a win finishes, every orb on the board is collected, their values are added together, and the total multiplies that spin’s payout. A spin with no win collects nothing, so an orb only matters when the reels connect around it.

Opening the gates to free spins

Three Skull Gate symbols open the main bonus, four open the Super Gates and five open the Epic Gates. Each starts with 10 free spins, and every Skull Gate that lands during the round adds one more. The Super Gates promise at least one orb worth 10x or more on every spin, and the Epic Gates at least one worth 25x or more.

This is where the game earns its ceiling. The bonus multiplier starts at 1x, and the orb total from each winning free spin is added to it for the rest of the round. Spins without a win leave it where it was, so the multiplier only ever climbs. Say the first winning free spin collects orbs worth 5x and 10x: the bonus multiplier goes from 1x to 16x. A losing spin leaves it at 16x, and a later win with a 20x orb lifts it to 36x. A well-fed round can end with every late win multiplied many times over.

Paying for a faster route in

Skull Gates has five bet modes, and the published Stake Engine math gives every one of them the same 96.70% return. The price decides how quickly you see the features and how often the cap is in reach:

The last column counts one purchase or paid spin, using version 4 of the game’s math; prices are in base bets
Mode Price per spin What it buys How often 50,000x lands
Base game 1x The standard spin 1 in 10 million
Gate Ante 3x More Skull Gates on the reels 1 in 3.3 million
Mystery Gate 300x or 500x A gate drawn at random, or none 1 in 1,650 (at the math’s 300x price)
Epic Gates 500x The top bonus round, opened straight away 1 in 990
Skull Storm 1,000x One loaded spin with no bonus round 1 in 550

The Mystery Gate is a gamble inside the gamble. Half the time it opens nothing and leaves two Skull Gates on the left-hand reels; otherwise it opens the Super Gates (40%) or the Epic Gates (10%). The published math table prices it at 300x the bet, while Stake’s game page lists it at 500x, so check the price on screen before you buy.

Skull Storm skips the gates altogether. Its single spin starts with a 2×2 Demon Wild in place, up to two extra Bone Wilds and between four and eight high-value soul-orbs. On a £0.20 bet it costs £200, and one of those spins is about 18,000 times more likely to hit 50,000x than a base spin, for 1,000 times the price. Every mode pays back the same 96.70% over time, so your budget should decide which one you use.

Knowing where Skull Gates runs

Glass Cannon builds on Stake Engine, so Skull Gates is a Stake exclusive, with stakes from €0.10 a spin in the Stake Engine listing. Stake’s terms list the United Kingdom as a country it does not take players from, and our breakdown of where Stake operates sets out the full picture. The free demo above needs no account, which is the easiest way to see the orbs and the bonus multiplier at work.

Setting it beside other multiplier slots

Skull Gates is the only Glass Cannon game we review so far, so the useful comparisons are other games built around multipliers. Captain Death doubles its multiplier after every tumble and stretches to 100,000x, where Skull Gates adds orb values to its bonus multiplier instead. Hel’s Domain puts its multipliers on the wilds themselves, and Gonzo’s Quest, the game that made falling symbols famous, keeps everything smaller with a 2,500x cap.

FAQ

Keeping a lid on the session

A 50,000x win comes along about once in 10 million base spins, so set a spending limit before you play and stop when you reach it. The purchase menu needs the most care: a single Skull Storm uses up 1,000 base bets in one go.
