Alchemy Gaming is a relatively new company with only eight slots in their portfolio prior to releasing Joker X UP. This piques our interest as we always enjoy seeing new studios trying to make their mark in the market. The game features 5 reels, 3 rows, and 243 ways to win. The theme of Joker X UP is old-school, with standard symbols, but the designs are impressive and visually appealing. The volatility level is estimated to be high based on testing, and the jackpot offers a substantial payout of 10,000x your bet. The minimum bet is £0.10, while the maximum bet is £20. The theoretical RTP is 96.22%, which is above average. The pay symbols can be categorized into low pays and high pays, with the diamonds offering the highest payout. Special symbols include Joker Wilds, which expand to cover entire reels, and X UP Scatters, which contribute to a win multiplier meter and can trigger the Free Spins feature. The Free Spins feature can also be triggered by landing three X UP Scatters at once. Players can use the Buy Bonus option to purchase the Free Spins feature or utilize the Upsizer feature to increase the win multiplier during Free Spins. Overall, Joker X UP offers a modern take on old-school slot machines with impressive production values, free spins, and the potential for big wins. Pros: visually appealing, high production values, free spins with win multipliers, potential for a 10,000x bet payout. Cons: none mentioned.
