Layout / Paylines
This slot runs a 5-reel, 3-row grid with 10 fixed win lines. Winning combinations form along any direction – left to right or right to left – as long as 3+ matching symbols land adjacent. No payline betting; all 10 lines are always active.
Symbols / Payouts
Seven regular symbols plus wilds. Gems span purple, blue, red, green, and yellow; bars and lucky sevens round out the set. Payouts scale with combo size:
Expanding Wild Respins
Wild symbols land only on reels 2, 3, and 4. When a wild hits, it expands to cover the entire reel. That triggers one free respin with the wild locked in place. If another wild lands during the respin, it locks too and another respin fires. Chain up to 3 consecutive respins this way. No dedicated free spins feature – respins are the game’s only bonus mechanic, and they hit often enough to sustain the low-volatility math.
RTP / Volatility / Hit Rate
Default RTP sits at 90.05%, though some operators offer 96.09% or even 99.06% depending on license tier. Volatility is low – expect frequent smaller payouts without brutal dry spells. Hit frequency runs 22.6%, meaning roughly one win per four spins on average. The tradeoff: max win caps at 500x the stake, so ceiling is modest by modern standards.
Betting / Mobile
Minimum bet 0.01, maximum 100. this slot runs on all mobile platforms – iOS, Android, browser-based. Same experience on phone or tablet as desktop. No download needed.
Why It Endures
this slot launched in 2012 and spawned a whole genre of cosmic-themed, both-ways-pay slots. Gorgeous retro-electronic soundscape and transparent reels with sparkling gems create genuine atmosphere despite its age. The expanding wild respin mechanic is clean and punchy – lock a wild, spin again, stack another if you’re lucky. Low volatility means the game doesn’t punish you for long stretches, and 22.6% hit rate keeps action flowing. Dozens of clones have tried to improve on the formula with bigger payouts and sharper visuals; none have dethroned the original.
