Rat King: a candy-themed cluster game on a 6x6 grid

Six-by-six grid with tumbling wins. Rat King is a 6-reel, 6-row cluster-pays slot from Push Gaming, released in July 2023. It uses a colourful candy theme with symbols like raspberries, cakes, puddings and lollipops. Wins form when 7 or more identical symbols touch anywhere on the grid, then vanish and let symbols tumble down as new ones drop in from the top. This cascade repeats until no more matches land. Collection boxes sit beneath the grid, gathering star multipliers and Rat King scatters for bonuses ahead.

Choose this slot if cascades excite you. Rat King suits players who enjoy frequent wins through cascading combinations and don't mind waiting for the bonus feature to land. It works best at stake levels from NZ$0.40 to NZ$10, though you can bet up to NZ$100. The game packs volatility high enough that bonus rounds may feel rare, so it's not ideal if you want a steady stream of payouts. Medium-bankroll players will find the feature buy option lets them jump straight to free spins if base play doesn't suit their session.

Rat King free spins reset multipliers. Free Spins reshape how Rat King plays. You enter this mode by collecting 3, 4 or 5 Rat King scatters during one round, earning 10, 15 or 20 spins. Each new Rat King collected adds 3 more spins. Star multipliers work differently here: they boost only the single spin they land on, then reset to zero. Base game multipliers carry through the whole round, but in free spins each one is a one-shot boost. This shift means bonus rounds play on their own rhythm.

Play mechanics

How one round of Rat King unfolds

You need these steps to understand what happens before your first payout

How much can you bet?

You select your bet amount from NZ$0.10 up to NZ$100, then hit spin. The six-by-six grid holds 36 positions where symbols land. Your wager stays the same for each round unless you change it.

Rat King cluster wins

When seven or more matching symbols touch each other anywhere on the grid, they vanish and pay you. The payout depends on which symbol matched and your bet size. Symbols can touch horizontally, vertically or diagonally.

What happens after you win?

After symbols vanish, the remaining ones drop downward and new symbols fall from the top. This continues until no more matches form. A Star Multiplier collected in the bottom row multiplies your wins for the whole round.

Scatter symbol collection

If you collect three, four or five Rat King scatter symbols in the collection boxes during one round, Free Spins start. You receive ten, fifteen or twenty free spins depending on how many you collected.

Before your session starts

Before you start playing, you can set a loss limit or a session time reminder through Monsterwin Casino's responsible gambling tools. These limits pause or block play once you reach them.

How do you start the bonus round?

Rat King scatters trigger the feature. Gather 3, 4 or 5 Rat King scatters in the collection boxes during one round to trigger 10, 15 or 20 free spins. Each additional Rat King collected during the feature adds 3 more spins. Star Multipliers apply only to the single spin they land on, then reset.

Rat King Push Bet explained. Turn on Push Bet to raise your stake by 20 percent and increase the chance of triggering free spins by 39 percent. Your payouts are still calculated from the base bet, not the raised amount. RTP rises from 96.30 percent to 96.34 percent when Push Bet is active.

How does the base game work? The base game runs on a 6 by 6 grid where clusters of 7 or more matching symbols anywhere on the board pay out. Winning symbols vanish, remaining ones collapse downward, and new symbols drop from the top, repeating until no further wins land.

What does nobody know in advance?

Bonus arrival stays random. The bonus round arrives at random intervals across your session. No streak, pattern or bet amount changes when the Free Spins feature will trigger. Every round has the same chance regardless of what came before.

Expect ups and downs. One session result follows no rule. The RTP of 96.30% describes long-term behaviour across thousands of rounds, not what you experience in a single sitting. Your actual return on any session could be higher or lower.

Can you reach the maximum? The maximum win of NZ$1,000,000 at your highest bet sits at the far edge of possibility. It occurs extremely rarely. Your typical wins will settle far below that ceiling.

Six things about Rat King

Common questions about Rat King

Answers to what matters before you place your first bet on this slot

Can I buy Free Spins on Rat King and what do they cost?+

You can buy your way into Free Spins at three levels. Buying 3 Rat King scatters costs NZ$1,000 at your example top bet and triggers 10 spins. At 4 scatters, the cost is NZ$2,500 for 15 spins. At 5 scatters, you pay NZ$5,000 for 20 spins.

Is Rat King a high volatility or low volatility slot?+

Rat King is a high volatility slot, meaning wins arrive less often but the payouts can be substantial when they do land. Large cascading sequences during a single round and the multiplier features support these bigger payouts.

What if I use the Push Bet or buy a bonus—does the RTP change?+

The base game RTP is 96.30%. With Push Bet active, it rises to 96.34%. Buying bonuses changes it further: 3 scatters takes it to 96.58%, 4 scatters to 96.63%, and 5 scatters to 96.93%. Each version applies only under that specific condition.

Can I trigger Free Spins naturally during the base game?+

Yes. Collect 3, 4 or 5 Rat King scatter symbols in the Collection Boxes beneath the grid during one round and you enter Free Spins. You get 10 spins for 3 scatters, 15 for 4, or 20 for 5. Additional Rat Kings collected during the feature add 3 more spins each.

Do I need to spend money to try Rat King in the demo?+

No. The demo section on this page lets you play Rat King with virtual credits. You see how the grid works, experience the cascades and test the features without wagering real money or winning real payouts.

Do I need to bet the maximum to play Rat King?+

No. You can bet as low as NZ$0.10 per spin or as high as NZ$100. The paytable scales with your bet size, so a win on a small bet pays proportionally less than the same win on a large bet.

When the fun stops being fun

Decide your session budget. Set a budget for your session and stick to it before you start spinning. This amount should be money you can afford to lose without affecting your bills, savings or daily life.

Rat King wins and walking away. Plan your stopping point in advance, whether you hit a win or a loss. Decide what a win feels like to you, and decide what loss would mean it is time to step away.

Set account-level safeguards. Use your account's deposit limits and loss limits to control your spending across all games. These tools work automatically and let you take back control if sessions start to feel out of hand.

Rat King can wait while you recover. Take a break or self-exclude if Rat King stops being entertainment and starts feeling like pressure. Gambling Helpline New Zealand (0800 654 655), Problem Gambling Foundation of New Zealand and The Salvation Army Oasis offer free support.
