CosmoX

At 97%, CosmoX sits nearly a full point above the 96.08% median we calculate from 9,062 catalogued returns — one of the higher figures on the board. Onlyplay released it on 12 November 2024 with an unusual Airplane theme.

The 97% in context

The 97% comes via a catalog feed, sourced from slotslaunch, and carries no second confirmation, so we mark it provisional rather than settled. It pairs with high volatility, level 5 of 5 — the steepest variance step we log. High return and high variance together mean the payback arrives in rarer, larger bursts, not a steady drip.

Who CosmoX is for

That level-5 rating points squarely at players comfortable with long gaps between wins. Bets run 1 to 50, a floor that already asks more than penny slots. Cautious grinders will likely find the variance uncomfortable; volatility-tolerant players are the honest fit here. Where we do track it, coverage is light: Cameroon 31st through one operator, Canada 151st, Switzerland 160th over two books, and Finland far down at 817th.

What our sheet doesn't show

Here honesty matters. Our records carry no reel count and no payline structure for CosmoX yet, so we won't guess at the grid. What we do confirm — no Megaways, no bonus-buy, no progressive — comes straight from the mechanics data. The Airplane theme is the one visual hook on file.

Even at 97%, roughly 3 units in every 100 wagered stay with the house over time — budget before the first spin. 18+.
