Wild Clusters, a Gems and Space slot
A 7x7 grid holds the board, and no fixed paylines decide a win. Five or more matching symbols that connect horizontally or vertically form a winning cluster. Winning clusters clear, the symbols above them drop down, and new symbols can complete further clusters in the same spin. The art follows two themes, Gems and Space, and the eight symbols are four gem colours and Heart, Club, Diamond and Spade.
Nine features are layered over the cluster mechanic. Progress Meter and Galaxy Features, Lucky Wilds, Mega Symbols and a Highlighted Special Symbol are all active in the base game. Random Wilds, Symbol Transform, Giant Symbol, Multiplier, Wild Multiplier and Level Progression round out the set.

Modes and their exact rules
Useful when you are choosing a bet size and want to know how each mode starts.
Five-wild cross formation
5 wild symbols start the spin in a cross formation at the centre of the grid. Cluster rules and cascades then follow the same 7x7 grid as the Base Game.
Main game screen5-wild cross
Wild Clusters Wild Blast multiplier
4 random Galaxy Features activate first. Then the Wild Blast feature places a 3x3 wild tile with a random x1/x2/x3/x4/x5/x100 multiplier, applied to any cluster it connects to.
Base gameWild multiplier tile
Single spin, dead-outcome follow-up
Only the four high-paying gem symbols fill the grid for a single spin. A dead outcome, one that does not win, automatically triggers the Wild Blast follow-up, with odds of 1 in 5.66 spins (17.66%). A winning outcome ends the round with that cluster's win only.

Play guide
Know where your money goes in every round
A common worry is missing a step, so each round follows the order the grid plays.
Pick a bet for your budget
Set the bet before each spin, anywhere from A$0.60 to A$100. The paytable is based on A$5, and every win scales with the bet you choose.
Before the fall, after the cascade
Five or more matching symbols linked horizontally or vertically on the 7x7 grid pay as a cluster. Winning symbols fall away and new ones cascade in until no new cluster forms.
Watch for Lucky Wilds
The base game also runs Lucky Wilds, Mega Symbols and a Highlighted Special Symbol alongside the clusters. A Progress Meter works with the Galaxy Features.
Three wilds first, clusters after
Wild Boost X3 starts the spin with 3 wild symbols in a horizontal line at the centre. The grid then plays out from that start, with the wilds linking clusters.

Play Options
Your First Visit to the Lobby
Read this before the first spin, when you decide between free play and a real stake.
From A$0.60 a spin, the real game needs a Rollxo Casino account and you must be 18 or older. The demo needs no money and pays nothing.
Play for realWhat can nobody know about Wild Clusters in advance?
The 96.82% base RTP is a long-run average over a very large number of spins, not a promise for one session. How often the bonus round comes is not known in advance, and the result of one session is random whatever the RTP. Two players on the same 7x7 grid at the same A$5 bet can see completely different sessions.
96.68% to 96.85% is the full RTP spread across the four versions of Wild Clusters. Which version runs at Rollxo Casino is shown only in the game rules, so check that panel before the first spin. Between two versions the difference is small next to the swing between two sessions.
x5,000 is the maximum win of Wild Clusters, a ceiling reached very rarely. At the A$10 top example bet it equals A$50,000, and at the A$100 highest bet allowed here it equals A$500,000. Whether any session gets close to that ceiling cannot be predicted.

What is the RTP of Wild Clusters and its versions?
96.82% is the base RTP of Wild Clusters, used by the Base Game and the Wild Boost X3 buy. The Wild Boost X5 buy returns 96.68%, Drop Dead Spin 96.79% and Wild Blast 96.85%. These are long-run averages per A$100 staked, not a result for one session.
What is the minimum and maximum bet on Wild Clusters?
A$0.60 is the lowest bet and A$100 the highest bet allowed on this site. The A$5 and A$10 amounts in this page are examples only.
Can I buy the Wild Clusters bonus, and what does it cost?
Wild Clusters has four feature buys, priced at 6x, 24x, 200x and 92x the total bet. At the A$10 example bet, Wild Blast costs A$2,000. Each buy costs the same multiple at any bet, so the price moves with the stake.
Can I play Wild Clusters in demo mode before staking money?
Wild Clusters lists its feature buys in FUN at a 2.00 bet, for example 12.00 FUN for Wild Boost X3 and 400.00 FUN for Wild Blast. Stakes in A$ work the same way, with each buy priced as a multiple of the total bet.
A calmer session with a fixed sum
Players must be 18+. In Australia, call the National Gambling Helpline on 1800 858 858 or register with BetStop, the national self-exclusion register.
Session budget in dollars
At A$10 per spin, one Wild Blast buy costs A$2,000, so set the session budget in dollars before the first spin and keep to it.
Walk away after a win?
x5,000 the bet is the maximum win. Set your stop point before the first spin and keep it after a win too.
Limits set before the first loss
The lowest bet is A$0.60 and the highest is A$100. Use your account's deposit and loss limits to keep the session inside a sum set in advance.
Breaks before the next buy
6x to 200x the bet is the feature buy range, so buys can drain money fast. Take a break or self-exclude with BetStop when fun stops.
