Mystic Reels: BGaming's Stone Circle Slot With Cascade+

Mystic Reels is a BGaming slot made with Bulletproof Games and released on 4 August 2026. It sits in the studio's #Classic category and takes its look from the ancient stone circles scattered across European history. Standing stones, floating orbs of light and coloured crystals fill the reels.

The game runs on 20 paylines with medium volatility and a 96% RTP. The maximum multiplier is ×4,558.7, which BGaming lists as a top win of €250,729. Portrait Mode is supported, and so is Free Spins API Support, a feature aimed at operators rather than players.

Cascade+ and the Wild

The core mechanic is Cascade+. When a winning combination lands, the symbols involved disappear and new ones drop in to fill the gap, so one spin can chain several wins. Cascades can also shorten the route to respins and Free Spins.

The Wild substitutes for every other symbol in the base game and completes winning lines. It also affects the multipliers in the bonus game.

Free Spins are triggered through Cascade+ and start with 7, 10, 12, 18 or 25 spins, depending on the trigger. During the round, Wilds raise the multiplier value, with a potential win above ×4,500.

Encore mode and Buy Bonus

Encore mode places stones beneath the grid. With it active, each time the Free Spins trail stops on an Encore stone, the player gets a respin. If another Encore stone is activated, a further respin can follow. Switching the mode on raises the total bet by 50%, and in return it enables free respins and doubles the Free Spins potential in the base game.

Buy Bonus lets players purchase the Free Spins feature for ×100 the bet. That guarantees 10 Free Spins, plus one extra spin that can add to the spin count through Cascade+.

A free demo is available on BGaming's website, so the cascades and Encore mode can be tried without staking real money. The game's ID is MysticReels, and its FS Rate is listed as 139.
