Fans of Alchemy Gaming’s other title Chronicles of Olympus X UP will definitely want to check out this addition to the X UP series. But it’s good to bear in mind that the Bolt X UP slot game is a less competitive experience and offers somewhat less challenging gameplay than the previous instalment with its very low RTP level. The Bolt X UP online slot has a medium variance and an average RTP of 96.22%, which means that it reflects the industry average and offers some pretty great chances overall. While slots like the Bolt X UP slot online run entirely on luck, it still pays to be prepared before starting up a spin. To win, you must land three or more matching symbols along a way. Your prize money is then determined by that symbol’s payout multiplied by your bet from 0.10 to 20. The reels showcase bold and colourful symbols, from the traditional card symbols to the unique fruit machine-inspired symbols, which include fruits, Liberty Bells, BARS, and Lucky Number Sevens, all powered by electricity! The wild of the Bolt X UP slot machine is guaranteed to appear as a full-reel symbol every time. It’s also possible to land an entire grid full of wilds, which is how you can bring home the slot’s top win. To the left is a multiplier metre, which is filled up by landing scatter symbols. 23 scatters can fill up the metre, at which point the free spins will be unlocked and the multiplier you’ve earned will be applied to all wins in the free spins.
