Pick a bet, and the 6x6 board gives you 36 positions to fill with sweets and rats, all under an arcade theme. There are no paylines or ways. Seven or more matching symbols anywhere on the board pay, and each winning group disappears. The remaining symbols fall down and new ones drop in from the top, so one spin can keep paying in a chain until no new wins form.
Watch the Collection Boxes under the grid, since they gather Rat King and Star Multiplier symbols from the bottom row. Collect three, four or five Rat King scatters in one round and you start 10, 15 or 20 Free Spins. Each extra Rat King adds three spins. A Star Multiplier in Free Spins applies only to the spin it lands on, not the whole round.
Game views
Many players wonder what the board and bonus look like before betting.
How to play
The worry is not knowing what happens after a spin, so these steps walk through one round.
Pick a bet from A$0.10 up to A$100 before you spin. Push Bet, when switched on, raises that bet by 20% and increases the chance of Free Spins.
Look for seven or more matching symbols anywhere on the grid. Winning symbols are removed, the rest drop down, and new ones fall in until no win remains.
Check the bottom row, where Star Multipliers and Rat King symbols go into the Collection Boxes. A collected Star Multiplier applies to the whole base game round.
Gather three, four or five Rat King scatters in one round for 10, 15 or 20 Free Spins. Each extra Rat King collected during the feature adds three spins.
Set your budget before the first spin and stop when you reach it. Nobody can know in advance when Free Spins will land, so plan each session around your budget alone.
Know what you win
The payouts below are in A$ at the example bet of A$0.20, and larger clusters of symbols pay more.
| Sweet symbol | 9+ | 11+ | 15+ | 20+ |
|---|---|---|---|---|
 Raspberry candy | A$0.80 | A$1.60 | A$4 | A$10 |
 Layered cake slice | A$0.60 | A$1.20 | A$3 | A$7.50 |
 Golden pudding | A$0.40 | A$0.80 | A$2 | A$5 |
 Swirl lollipop | A$0.20 | A$0.40 | A$1 | A$2.50 |
 Sprinkled donut | A$0.18 | A$0.32 | A$0.80 | A$2 |
 Round macaron | A$0.16 | A$0.24 | A$0.60 | A$1.50 |
Each bonus buy costs a fixed multiple of your bet, so the price moves with your stake. The table gives prices at the top example bet.
| Bonus buy | Cost (A$) | RTP |
|---|---|---|
| Three Scatter bonus buy | x100 · A$50 | – |
| Four Scatter bonus buy | x250 · A$125 | – |
| Five Scatter bonus buy | x500 · A$250 | – |
Check the return first, because return to player is the share of each A$100 staked that the game pays back over time. The version running here is shown in the game rules.
| RTP setting | RTP | Provider default |
|---|---|---|
| Variant 1 | 96.93% | Not available |
| Variant 2 | 96.63% | Not available |

Rat King modes
Read this before your first spin, or when Rat King symbols start landing on the grid.
Collect 3, 4 or 5 Rat King scatter symbols in the Collection Boxes during one round to start Free Spins, for 10, 15 or 20 spins. Each further Rat King collected retriggers +3 spins. A Star Multiplier applies only to the spin it lands on, then resets.
Base Game spinsRetriggered spins
Switch Push Bet ON if you want a higher chance at the Free Spins Feature. This optional ON/OFF toggle raises your Base Bet by 20%. The on-screen label reads 'increase chance to win feature by 39%'. Wins are evaluated on the Base Bet, not the Push Bet amount.
Before each spinHigher feature chance
Place your bet and spin the 6x6 grid, which has no paylines. Matches of 7 or more identical symbols pay. Winning symbols vanish, the rest drop down, and new ones fall in, until no wins remain. Collection Boxes gather Star Multiplier and Rat King symbols from the bottom row.
Before spinningCluster wins
Choosing a bet and sitting down for a Rat King session means accepting that the bonus round may come early, late or not at all. How often the Free Spins Feature starts is not known in advance. Single spins are random, and the result of one session stays random whatever the RTP. Two players with the same bet can finish with opposite results.
Before you bet, open the game rules and find which RTP version runs in this lobby. Only the game rules show that version. Read the figure once, before the first spin, so you know which version you are playing.
Planning around the top prize means treating the maximum win as a ceiling, not a target. The ceiling is 10,000 times the bet in one round. It is reached very rarely, and no one can say when a round will get there.
Players must be 18+. For help in Australia, call the National Gambling Helpline on 1800 858 858, or register with BetStop, the national self-exclusion register.
Set a spending limit before you open Rat King. Stop once the money is gone, and do not add more to chase losses.
Decide your stop point before the first spin, even after a big win. A win can tempt you to keep going, so set the plan in advance.
Use the deposit and loss limits in your account before you start, and keep them in place rather than raising them mid-session.
Take a break as soon as Rat King stops being fun. If breaks do not help, self-exclude through BetStop.

Six short replies
Plain answers first, so you know the game before you bet, the way we run every page.
A single round pays up to 10,000 times the current Base Bet. At the A$0.50 example bet that comes to A$5,000, and at the A$100 maximum bet the cap is A$1,000,000.
Yes. The buy starts Free Spins directly with 3, 4 or 5 Scatters, at a cost of A$50, A$125 or A$250 at the A$0.50 example bet.
The lowest bet is A$0.10 and the highest is A$100. A$0.20 and A$0.50 appear here only as examples, not as limits. Turning on Push Bet raises the Base Bet by 20%.
Rat King has a top prize of 10,000 times the bet, but how often Free Spins trigger cannot be known in advance. One session can end well below or well above the stake.
Rat King comes in five RTP versions, from 96.30% to 96.93%. With Push Bet on, the RTP moves from 96.30% to 96.34%, and the Free Spins become more likely.
Collect 3, 4 or 5 Rat King Scatter symbols in the Collection Boxes during one round to get 10, 15 or 20 Free Spins. Each further Rat King collected during the feature adds 3 more spins.
