Six reels of three rows spin across 10 fixed paylines in a Cats and Egyptian theme. Bastet, golden cat statuettes, pharaoh cat masks and the Key of Nile sit among the card symbols. Two matching symbols on a payline can already pay. Reel 6 is locked except its middle cell, and when that open cell matches a winning combo on reels 1 to 5, it expands to fill all three rows, lifting the win.
Three or more Golden Book scatters trigger 10 free spins. The symbol in reel 6's open cell at that moment becomes the expanding symbol. Whenever it lands, its whole reel fills with it, and it pays on any position on the lines played. The Gamble card game doubles the stake on a colour guess or quadruples it on the exact suit.
RTP means return to player: the game pays back this share of each A$100 staked over many spins. Single sessions can differ. The version Kudos Casino runs is shown in the game rules.

Five steps in order
Unsure what happens between the bet and the payout? The steps below show each stage in order.
Bets run from A$0.10 to A$10 per spin. The paylines stay fixed at 10, so the total bet is the amount you choose before each spin.
Two or more matching symbols on a payline pay. Reel 6 is locked except its middle cell, which expands to fill the reel only when it matches a winning combo.
Base game features include Scatter and Wild symbols. After any win, Gamble offers a colour guess for double the stake, or a suit guess for four times the stake.
Three or more Golden Book scatters trigger 10 free spins. The symbol in reel 6's open cell at that moment becomes the expanding symbol, filling any reel it lands on.
Set your limit before the first spin, as every spin draws from your chosen bet. Stop once the planned amount is gone, since no session result can be known in advance.
When scatters land
This block settles how each round starts, what the player gets, and how the gamble works.
Three or more Golden Book scatters start 10 free spins. The symbol in reel 6's open cell at trigger becomes the expanding symbol. When it lands, that reel fills with it across 3 rows and it pays on any position of the lines played. Retriggers are possible.
Base game spins10 free spins
The reels jump from the base game straight into Free Spins after one fixed-price purchase of 97x total bet. At a A$0.10 total bet it costs A$9.70 and scales with the bet. RTP changes from 96.99% to 96.83% when bought. It is off during a bonus round.
Base gameFree Spins now
A win on the reels opens the gamble, and a face-down card appears. Guess its colour to win x2 the stake, or its exact suit to win x4 the stake. A wrong guess loses the stake. The gamble is capped at 1/4 of the game's max win.
After a winx2 or x4
Six reels of three rows spin across 10 fixed paylines. Reel 6 stays locked except its middle cell. If that open cell matches a winning combo on reels 1 to 5, it expands to fill all 3 rows of reel 6 and boosts the win.
Before first spinBoosted line wins
Each spin lands symbols on the six reels, and nobody can tell which spin will bring the Golden Book scatters that open the free spins. How often the bonus round comes is not known in advance. The result of one session is random whatever the RTP figure. A long run of quiet spins says nothing about the next one.
Every spin across the six reels runs under one of two RTP versions. The game rules are the only place that names the version in use at Kudos Casino. Two versions can return different amounts over time, so the version matters when you compare this slot with another.
Expanding symbols can fill whole reels and lift a win, yet the maximum win stays a ceiling reached very rarely. Reaching it is not something any spin can be relied on to do. Read the maximum as the edge of what the game allows, not as an expected result.
