Diamond Symphony DoubleMax

Diamond Symphony DoubleMax Overview

Diamond Symphony DoubleMax is a neon, music-themed slot built by Bulletproof Games and released through Yggdrasil on 20 June 2023. Yggdrasil’s official game page lists an RTP of 96%, medium-high volatility, a 25% hit frequency and a top multiplier of 20,000x (capped at €1,000,000), with bets from €0.20 to €50. SlotCatalog shows a 94% default and RTP ranges, so the version at your casino may differ.

Grid, Lines and Symbols

The game uses a 5x3 grid with 20 fixed paylines that pay left to right. The top symbols are the diamond and the conductor wild, followed by the grand piano, violin and trumpet; the low pays are glowing neon music notes and treble clefs. There are no scatters. According to SlotCatalog, diamonds and wilds pay 10x the bet for five on a line, while the piano, violin and trumpet reach 5x, 3.5x and 2.5x.

Cascades and the DoubleMax Multiplier

Every win removes the winning symbols, leaves a wild behind and drops new symbols in from above. The DoubleMax meter on the right of the reels tracks the multiplier: our screenshots show it at x1, then x2 after the first cascade, with x4, x8, x16 and x32 stacked above. In one spin at a €12 stake a line of 3.20 was doubled, and the cascade sequence ended with total wins of €6.40.

Encore

The Encore option raises the stake by 50% without changing the payouts; the stake panel in our screenshot shows €8.00 plus a €4.00 encore for €12.00 in total. With Encore switched on, extra ENCORE steps appear on the ladder beside the reels.

Free Spins

The ladder on the left of the reels leads to 7, 10, 12 or 15 free spins, and one of our sessions reached the top step: “You have won 15 free spins”. During the free spins the DoubleMax multiplier does not reset between spins, which is where the 20,000x ceiling comes into play. A Buy Bonus button, marked with a diamond, sits under the Encore switch.

Climbing the Ladder

With no scatters on the reels, the route to the bonus is the ladder itself. Our three base-game screenshots show it filling as a cascade sequence goes on: with the multiplier at x1 no step is lit, at x2 the first chevron is lit, and in a longer sequence at a €0.20 stake the multiplier had reached x4 with four chevrons lit while a small 0.40 line was being paid. The free-spin awards sit at the top of the ladder, so the longer a cascade chain runs, the closer it gets to them.

Betting Range

SlotCatalog describes a fairly narrow range of ten levels, from €0.20 to €50 per spin; our screenshots were taken at €0.20, €3 and €12 (the last one including Encore). The 20 lines cannot be changed.

A Sequel

This is Bulletproof Games’ follow-up to its original Diamond Symphony from 2019. The neon stage, the orchestra symbols and the Encore option carry over; the DoubleMax multiplier that keeps doubling through the cascades is the new element.

Who It Is For

Diamond Symphony DoubleMax suits players who like cascading slots with a clear multiplier path and a disco look. Bulletproof Games also made Blackbeard – Battle of the Seas for Yggdrasil.
