Diuamond Symphony DoubleMax Base Game

Diamond Symphony DoubleMax Base Game and Features

Diamond Symphony DoubleMax is a 5-reel slot with 20 fixed pay lines. Winning combinations are formed when 3 or more of the same symbols land from left to right, starting from the leftmost reel.

The minimum bet available here is £.€0.20 per spin and the maximum bet available is £.€100 per spin, with plenty of other options in between the two. This game has a theoretical RTP of 96.00% and a max win cap of 20,000x.

In terms of symbols, the highest-paying regular symbol here is the Diamond, followed by the Piano, Violin, Trumpet, and Musical Note. Low-paying symbols fall to Pink, Blue, Green, and Purple Musical Notes. Wilds substitute for all High and Low-paying symbols.

Each time a winning combination forms, all winning symbols will be removed from the reels, and new symbols will drop down via a Cascade. However, one of the winning symbols will transform into a Wild symbol to replace the previous winning symbol.

After each Cascade, you will move one position up the Free Spins Trail on the left side of the reel set. After 4 consecutive wins in a row, you will reach 7, 10, 12, and 15 Free Spins on the 5th, 6th, 7th, and 8th positions on the Free Spins Trail respectively.

Each time a winning combination is formed, resulting in a Cascade, you will climb to the next Win Multiplier. The Win Multiplier starts at x1, and Doubles with each Cascade, with an infinite Win Multiplier.

When no more winning combinations form, the Win Multiplier will reset back to x1. The Win Multiplier is applied to all winning combinations that form during that particular spin.

Encore Feature

Before you can begin spinning, you will be given the option to activate the Encore Feature. Activating the Encore feature will increase your current bet by 50%.

This feature alters the 2 positions before Free Spins on the Free Spins Trail to Encore positions. If you should reach an Encore position, a free Respin is awarded.

During the Respin, your position on the Free Spins Trail is held, making it easier to not only reach the Free Spins positions but win a higher number of Free Spins.

The Encore feature Doubles your chances of triggering the Free Spins round. If you land on the first Encore position and the Respin moves you to the next Encore position, you will be awarded an additional Respin at your current trail position.

Diamond Symphony DoubleMax Free Spins

Once you reach one of the Free Spins positions on the trail, depending on which position you land on, you will begin the Free Spins round with 7, 10, 12, or 15 Free Spins.

Once Free Spins are triggered, you will be given the option to Gamble your current number of Free Spins for more via a Gamble Wheel. The Gamble Wheel is only available to those who landed under 15 Free Spins.

Once active, you will be given 2 Gamble Options, as follows.

  • Low GambleAllows you to gamble your Free Spins for a lower number of Free Spins, with a higher chance of winning.
  • High Gamble – Allows you to Gamble your Free Spins for a higher number of Free Spins, with a lower chance of winning.

The chance of winning the Gamble is shown as a Green Segment, and the chance of losing is represented by the Red Segment. You can choose to gamble multiple times or until the maximum number of Free Spins are won. Losing the Gamble will result in all Free Spins being lost and the round ends.

During Free Spins, the Free Spins Trail and Win Multiplier are in play. With each new Free Spin, your progress on the Free Spins Trail is reset.

The Free Spins Trail works in the same way it does in the base game, but with a few adjustments. The Free Spins Trail is equipped with +3, +7, +10, +12, and +15 additional Free Spins positions. The modified Trail makes it easier for you to retrigger the Free Spins round.

Diamond Symphony DoubleMax: Our Verdict

Diamond Symphony DoubleMax had all of the emotions that you might feel when listening to a heartfelt composition. Sadness, joy, excitement, anticipation and just about everything in between.

It looks rather simple visually, but we’d have quite liked Diamond Symphony to be a musical marvel given its name, but it’s not really. The sounds aren’t the worst, and neither are the graphics, but nothing overwhelms you.

When it comes to gameplay, Diamond Symphony can be quite exciting with the selectable Encore mode, the Multipliers, cascading symbols and the wild symbols that fill their place to keep the momentum going.

During Free Spins the pace picks up as it should, and the Free Spins trail is adorned with additional free spins to keep it going, all while growing the multiplier.

Overall, Diamond Symphony DoubleMax does stand out as a game with potential, excitement and allure, but no more so than other DoubleMax slots.
