Diamond Symphony DoubleMax is a Bulletproof Games title, which will be available at Yggdrasil casinos. The DoubleMax mechanic is big enough to be included in the slot’s name, and we’ve seen it at play in several other releases in recent years. It’s a music-themed game in this case, which is unusual, but not unheard of.

Diamond Symphony has a regular game area, with its 5×3 reels spinning and giving us 20 paylines. It seems like the DoubleMax mechanic is doing its job and a top jackpot of 20,000x the stake could be claimed inside. With medium-high volatility and a 96% RTP, that sort of jackpot looks appealing. You should also expect cascading reels, wilds, and a free spins feature.

Betting and Prizes

A small bet of $0.20 will trigger your next spin in Diamond Symphony DoubleMax. Of course, there is also the option to spend more, and the bet can be increased up to $50.

Going after a 20,000x top jackpot is always something that players enjoy doing, though the very high volatility commonly associated with these prizes can be a turn-off. It’s somewhat lower of a risk in this slot, which is classified as medium-high volatility, but I wouldn’t be too confident about getting close to the big prize in any case. A 96% RTP is possible, but there are also lower settings.

Diamond Symphony Game Features

One way to form combinations is with regular symbols, but it’s also possible to get wild symbols to help you.

Either way, once a combo gets formed, a cascade mechanic follows and replaces the winning symbols with new ones. It will also leave a wild symbol in one of the available positions. With each cascade, the DoubleMax mechanic also kicks in and doubles the multiplier for the next winning combinations. Interestingly, the multiplier has no upper limit, but it resets between rounds.

If you can get 5 or more cascades in a row, the game triggers 7 to 15 free spins. The main difference is that the DoubleMax multiplier keeps doubling and only resets at the end of the free spins.

Theme & Design

Music-themed slot machines are uncommon, but we got several over the years. It’s not dedicated to a particular music style, so we see pianos, trumpets, bass, and musical notes. A lot of neon coloring has gone into the design of these symbols, making them look almost futuristic, despite the classic influence of its instruments.


Diamond Symphony demo manages to be interesting overall, with big wins, a DoubleMax mechanic that can be quite powerful, and a music theme that is general enough to be acceptable for most players. It’s a mix we’ve seen before, but it could still be fun to play.
