Diamond Cascade is a gem-themed slot with cascading wins

How cascading wins build momentum
Diamond Cascade is a 5x5 gem-themed slot where wins trigger a cascade mechanic. Released in July 2023, the game uses 50 fixed paylines and groups symbols by background colour. When you form a winning line, matching colour clusters of five or more explode and cascade down, refilling from the top until no more clusters qualify. This tumble effect can chain across a single spin, building your win multiplier with each cascade.
Play if you tolerate long gaps between wins
You will find this slot suits players who can sit with longer dry spells between wins but enjoy the potential for substantial payouts when they land. With high volatility, wins come less often and can be much bigger. The slot accommodates bets from A$0.20 to A$240, so both cautious and bold players can find their level. The Ante Bet option raises your chance of triggering free spins if you prefer a higher probability of reaching the bonus.
Free spins multiply differently than base game
The Free Spins round changes how your multiplier works. In the base game, your win multiplier resets between each spin, but during free spins it keeps building and stacking across every cascade until the round ends. This accumulation means a single free spin session can produce far larger totals than base game spins. You start with 15 free spins and can retrigger more by landing three or more scatters within the bonus round.

One round explained

Spin, match, multiply, repeat

Follow each step of a Diamond Cascade round, from picking your bet to collecting your payout.

  1. 1

    Bet from A$0.20 to A$240

    You choose your bet before each spin, ranging from A$0.20 to A$240. The game shows your total bet and the potential payout for that stake. You can raise or lower your bet between spins or activate Ante Bet to increase your odds of triggering the bonus.

  2. 2

    Three matching symbols pay

    The five reels spin and land symbols across 50 paylines. When three or more matching gems align left to right on adjacent reels, you win and that line pays out. Your win appears immediately as the symbols settle.

  3. 3

    What happens after you win?

    After a win, symbols of the same background colour vanish in clusters of five or more, and new symbols cascade down from the top to fill the gaps. This repeats until no more clusters match. Every 20 cascading symbols trigger a multiplier boost of up to 50x or multiply your total by 2x, 3x, 5x or 10x.

  4. 4

    Entering the bonus round

    Hit three or more Scatter symbols anywhere on the reels to enter Free Spins and start with 15 spins. Land more Scatters during the round to add 5, 10 or 15 extra spins. The multiplier you build during Free Spins keeps climbing across every spin until the round ends.

  5. 5

    Spend and time limits

    Before you play, set limits on how much you spend and how long you play using Kinghills Casino tools. You can set deposit limits, session reminders, cooling-off periods and self-exclusion. These controls help you stay in charge of your play.

When the cascade multiplier grows

Base game cascades versus bonus multipliers

Raise your bet for better odds

You can raise your bet by 25 percent to increase your natural chances of landing Scatters and triggering the Free Spins round. The Buy Free Spins option becomes unavailable when you activate this higher-stake mode.

How many Scatters do you need?

You need three or more Scatters to start 15 free spins. Land three, four, or five Scatters again during the round and you gain five, ten, or fifteen extra spins respectively. Your multiplier keeps building across all spins instead of resetting.

Jump into bonus whenever you want

You can pay 100 times your current bet to skip straight into the Free Spins round, where three, four, or five Scatters will trigger randomly on that entry spin. This option is blocked when you have the Ante Bet active.

Multipliers build with every cascade

Your 5x5 grid fills with coloured gem symbols across 50 fixed paylines. When three or more matching gems land on adjacent reels from left to right, they vanish, symbols cascade down, and new ones fill from above. Every 20 symbols you clear this way triggers a random multiplier boost applied to your total win.

The honest limits

Diamond Cascade keeps some outcomes hidden

When Free Spins arrive is unpredictable

The bonus round may take many spins to arrive, or show up early. No pattern reveals when three or more Scatters will land, so budget for long gaps between Free Spins rounds.

Your session result stays independent

The RTP of 96.06% describes average returns across thousands of sessions, not the outcome of yours. One session may lose or win heavily, whatever the percentage says.

Treat the maximum win as a ceiling

The maximum win of A$40,000 at your example top bet is a ceiling so rare that you should not plan for it. Most winning sessions will be much smaller.
