96.54%. That’s Cosmic Clusters running on Ante Bet 1, against 96.45% at normal stake. The ante is normally a surcharge for reaching the feature sooner, priced accordingly. On this space-themed slot, it also happens to be the best-returning of the six configurations the game ships with.
Ante Bet 1 lifts the bet multiplier from 20x to 30x and makes the natural free spins trigger two and a half times more likely. Ante Bet 2 pushes the multiplier to 50x for five times the chance, and pays back 96.47%, which is less than the cheaper option’s returns. Every figure in this review comes from the game’s own information pages, where all six settings sit side by side.
The counterargument is fair. Nine hundredths of a percentage point is invisible across any session you’ll actually play, and paying half as much again per spin to collect it is a rounding error with a strategy costume on. The ante really buys frequency. Free spins arrive roughly once in 294 spins at normal stake, and that wait is the hardest thing about the game.
The studio’s better-known cluster pays titles start from a different idea. Sugar Rush 1000 runs a 7×7 board with multipliers pinned to grid positions, while this one is 6×6 and hangs everything on collectable coins.
The art is bright and cheap in the best way. A cartoon astronaut floats beside the reels, the backdrop is a purple nebula, and the symbol set includes a rainbow crystal cluster, a green alien head, a satellite, a UFO, and five coloured gems.
Every tumble that produces a win drops a wild into a random empty position before the next symbols fall. It’s automatic and unconditional, so a chain of four tumbles seeds four wilds, and the grid grows steadily more connected the longer a sequence runs. The astronaut substitutes for everything except the scatter.
Coins land in three grades. Bronze carries 0.5x, 1x or 2x. Silver carries 3x, 5x or 8x. Gold runs 10x, 15x, 20x, 25x, 50x, 100x, 200x, 500x or 1000x. The clearing sweep leaves all of them alone, and they only pay when five or more connect. When that happens, the values add up, the coins explode, and a single new coin carrying the total drops into an empty position.
Read those grades against the right number. Money values are multiples of the base bet, and normal play sets the base bet at one twentieth of your total stake. Stake $2.00 and the base bet is $0.10, so a top gold coin of 1000x pays $100. Against that $2.00 spin, it’s 50x, one per cent of the 5,000x limit the game pays at most.
Three, four, five or six scatters award 12, 15, 18 or 21 free spins. Inside the round, the coins change character. Any money symbol that lands without joining a cluster falls to the bottom of the grid and stays put until a cluster forms or the spins run out, and symbols that vanish in a tumble without being part of the winning combination turn into money symbols themselves. Special reels are in play throughout, and the lower rows fill with coins waiting on a fifth neighbour.
Retriggers are capped hard. Two or more scatters during the round add two more spins, no matter how many land or how often it happens. Genre siblings tend to hand back a full round; this one gives you a pair.
The feature panel lists three purchases. 100x your total bet triggers the standard round at 96.48%. 300x buys the Super version, which strips bronze coins out so only silver and gold appear, and returns 96.44%. 1000x buys the Epic round, gold coins only, at 96.53%. Purchase costs are quoted as multiples of the total bet rather than the base bet, so the arithmetic runs the opposite way from the coin values, and the demo carries all three buttons.
Land a winning cluster and the game doesn’t just clear the symbols that formed it. Every other instance of that symbol disappears too, wherever it sits on the 6×6 grid, which is why a five-symbol win can empty a third of the board in one step. Scatters and money symbols are exempt and stay exactly where they are.
Clusters need five or more matching symbols connected horizontally or vertically. Diagonals don’t count, so coverage is what you’re reading rather than lines, the same shift in thinking that grids like the Reactoonz 2 demo ask for. Symbols above the gaps fall, fresh ones refill from the top, and the sequence keeps going until a tumble produces nothing new.
Stakes start at $0.20. A special bets toggle on the left rail holds the two ante levels, and both work by moving the multiplier that sits between your coin value and the total you stake. Something pays on roughly 24.5% of spins, about one in four, which is the sort of figure free play settles quickly.
The active configuration shows on the information pages, and the spread across the six is narrow enough that the ordering matters more than the gaps.
| Setting | Bet multiplier | RTP |
|---|---|---|
| Normal play | 20x | 96.45% |

Every value below is a multiple of the base bet, which normal play fixes at a twentieth of the total stake. At the $0.20 minimum, that’s one cent.

A round that reaches 5,000x your bet stops there. The win is awarded and anything still queued in the feature is forfeited.
