Temple Quest: Spinfinity from Big Time Gaming arrived in 2018 as one of the earlier showcases for BTG’s mechanical creativity before Megaways became the industry standard. The “Spinfinity” in the title isn’t just branding — it refers to a genuinely unlimited reel expansion system that makes the game unlike almost anything else available at the time of release.

Rather than fixed paylines, Spinfinity runs on a cascade mechanic where every consecutive winning cascade adds extra rows to the reels — with no upper limit on how tall the grid can grow. Bets range from $0.20 to $200 per spin. The adventure theme is set in an ancient jungle temple, complete with crumbling stonework, golden idols, and the kind of lush colour palette that makes the game feel genuinely adventurous rather than generic.

The Temple wild triggers instant prize awards when it lands, and every cascade reaction following a win adds unlimited additional reel rows to the active grid. There’s no cap — in theory, a single spin can generate an ever-expanding reel tower as long as winning combinations keep appearing. Free Spins are also part of the package, giving the Spinfinity mechanic room to compound over multiple free games.

Big Time Gaming set the RTP at 97%, which is notably generous and positions this as one of the higher-returning slots from a major developer. Volatility is high, so the return doesn’t come in steady drips — it arrives in bursts when the cascade mechanic gets moving. The max win is 3,000x your stake, which, while not headline-grabbing by modern standards, can be reached through the compounding cascade system.

Temple Quest: Spinfinity is a smart pick for players who want a high-RTP adventure slot with a genuinely original mechanic. It rewards those willing to let sessions run long enough for the cascade engine to fire properly.
