Cosmic 5×3 Mechanics & Bonus Math
Twenty-five paylines across a 5×3 grid — standard left-to-right matching with 3+ symbols. Winning combinations cascade: the winning symbols disappear and new ones fall from above. Chains continue until no new wins form. Each cascade level increases a global multiplier: 1x on the first win, 2x on the second cascade, 3x on the third, and so on. Five cascades deep and everything pays at 5x.
Hidden Bounty is the headline mechanic. Certain grid positions contain hidden rewards underneath the visible symbols. When a cascade clears those positions, the hidden bounty reveals itself — it could be a multiplier boost, a Wild symbol, or a direct coin value. You never know which positions hold bounties until you clear them. It adds a treasure-hunting layer to the cascade system.
The UFO Feature triggers randomly during any spin. A UFO crosses the grid and transforms 2-5 symbols — turning them Wild, adding multipliers to existing Wilds, or converting low-pay symbols to premium ones. Full Clear Feature activates when cascades clear all 15 grid positions in a single spin. The reward is a substantial bonus payout — think of it as the jackpot for cascade chains. Random Wilds can appear on any spin independent of other features.

Bonus Mechanics Explained
6 mechanics drive the 5,000x max win. Here's exactly how each one works.
Hidden Bounty
How to Trigger
A cascade clearing a grid position that hides a reward.
What Happens
Certain positions on the 5x3 grid hide a reward beneath the visible symbol. You cannot see which until a cascade win clears that spot, then the bounty reveals as a 2x-5x multiplier, a Wild, or a direct coin value. It turns every cascade into a dig for buried treasure.
Multipliers
Revealed boosts run 2x to 5x, or a Wild, or coins.
Odds (est.)
Positions are invisible, so there is no way to target them.
Strategy
You cannot steer it. Longer cascade chains simply clear more positions and expose more bounties.
| Reveal | 2x-5x / Wild / coins |
| Positions | Hidden |
| Grid | 5x3 |
| Trigger | Cascade clear |
| Control | None |
Cascade Wins + Multipliers
How to Trigger
Any winning combination, which then cascades.
What Happens
Winning symbols vanish and new ones drop in, chaining until no fresh win forms. Each cascade level lifts a global multiplier: 1x, 2x, 3x and up, so a 10x base pay on the fifth cascade settles at 50x. The multiplier resets at the start of every new spin.
Multipliers
Global multi grows 1x per cascade level.
Odds (est.)
Hit frequency near 24%; deep chains are rare in the base game.
Strategy
High variance rewards patience. Hidden Bounty Wilds can extend a chain and push the multiplier higher.
| Per Cascade | +1x |
| Reset | Each spin |
| Hit Freq | ~24% |
| Lines | 25 fixed |
| Cap | 5,000x |
UFO Feature
How to Trigger
Fires at random on any base or Free Spins spin.
What Happens
A UFO crosses the grid and transforms 2 to 5 symbols. It can turn them Wild, add a multiplier to an existing Wild, or upgrade low pays to premiums. It lands with no scatter requirement and always helps the board.
Multipliers
Adds Wilds or boosts existing Wild multipliers.
Odds (est.)
Roughly one visit every 20-30 spins, though it can cluster or vanish.
Strategy
The swing moment is a UFO firing mid-cascade when the global multiplier is already built up.
| Transforms | 2-5 symbols |
| Trigger | Random |
| Where | Base + FS |
| Rate | ~1 per 20-30 |
| Effect | Always positive |
Full Clear Feature
How to Trigger
Cascades clearing all 15 grid positions in one spin.
What Happens
When a single spin cascades until every one of the 15 positions is emptied, a large bonus payout lands on top of the cascade wins already banked. Reaching it usually needs Hidden Bounty reveals and a UFO assist feeding the chain.
Multipliers
Payout scales with the accumulated cascade multiplier.
Odds (est.)
Around 1 in 10,000 base spins; payouts land near 500x-2,000x.
Strategy
It is a chase target, not a plan. Free Spins with boosted Wilds give the best shot.
| Clear | All 15 tiles |
| Payout | ~500x-2,000x |
| Odds | ~1 per 10,000 |
| Needs | Bounty + UFO |
| Cap | 5,000x |

STAR TREASURE FAQ
Got questions? We've got straight answers.
Base RTP is 96.45%, with the buy feature running at 96.40%. Both are above the 96% industry average. WIN FAST Games certifies through GLI testing. Some casino operators may offer lower RTP versions, so always check the in-game info panel. The 0.05% difference between base and buy is negligible — play whichever mode you prefer without worrying about RTP loss.
Certain grid positions have hidden rewards underneath the visible symbols. You can't see them — they're completely invisible. When cascade wins clear those specific positions, the bounty underneath reveals itself. It might be a 2x-5x multiplier, a Wild symbol, or a coin value added to your win. Think of it like scratching a lottery ticket — you're digging through symbols hoping something valuable is buried underneath.
It's completely random — there's no scatter requirement or specific symbol combination. The UFO simply appears during certain spins and transforms 2-5 symbols on the grid. It can show up in base game or during Free Spins. The transformations are always beneficial: Wilds, multiplier boosts, or symbol upgrades. You can't influence when it triggers. Average frequency is roughly every 20-30 spins, though it can cluster or disappear for 100+ spins.
Very rare. Clearing all 15 positions requires a cascade chain that removes every symbol on the grid. In base game, it might happen once in 10,000+ spins. During Free Spins with boosted Wilds and Hidden Bounty reveals, the probability increases but it's still an outlier event. Most sessions — even long ones — won't produce a Full Clear. When it happens, the payout is typically 500-2,000x depending on accumulated cascade multipliers.
No — the multiplier resets to 1x at the start of each new spin. It only grows within a single spin's cascade chain. First cascade = 1x, second = 2x, third = 3x, and so on. The multiplier applies to each winning combination at that cascade level. This means a single spin with 6 cascades can produce more than 50 separate spins would, because that 6x multiplier transforms even small base wins into meaningful payouts.
