Pros & Cons

Pros Cons
Engaging space and gem theme with visually appealing graphics Lower than average RTP at approximately 94%
Features such as expanding wilds and respins enhance gameplay Limited betting options with a max bet of $20
Accessible on both desktop and mobile platforms Low maximum payout of 250x the stake

Minimum and Maximum Bet

The betting options in Cosmic Jewels are designed to accommodate a range of players, with minimum bets starting at $0.50 and maximum bets capped at $20.00 per spin. This range aims to cater to casual players more than high rollers, reflecting the game’s broader accessibility and medium volatility gameplay.

Game Jackpot

The maximum win in Cosmic Jewels is set at 250 times the stake, which aligns with the game’s low to medium volatility. The Return to Player (RTP) is relatively low at approximately 94%, suggesting a lower return over extended play periods compared to other slots. This variance and RTP combination suggests that while wins may be frequent, they are likely to be smaller in value, making it ideal for players looking for longer play sessions with a moderate bankroll.

How To Play

  • Open the game: Start by loading Cosmic Jewels on your chosen device.

  • Play the game: Hit the spin button to start the game. You can also use the autoplay feature to play multiple spins automatically.

Cosmic Jewels offers an engaging slot experience with its attractive space-themed graphics and sound design. While the game features entertaining mechanics such as respins and expanding wilds, its lower RTP and relatively modest betting options might not appeal to all players, especially high rollers. Nonetheless, for those interested in a visually appealing game with medium volatility, Cosmic Jewels stands out as a solid choice. Players are advised to approach the game with a strategy for managing their funds, given the RTP and the game’s payout structure.
