The Diamond Charge Extra slot was launched onto the online casino industry early in 2026, joining the impressive range of games that belong to Iron Dog Studios. The Diamond Charge Extra title shares characteristics with many retro-style online slots, featuring simplistic visuals that evoke a traditional slot machine theme. Despite being visually simplistic, Iron Dog Studios has added a selection of bonus features to the gameplay that may be triggered at random.

Diamond Charge Extra Game Background


A layout commonly found in other classic slots in the industry has been used in this title, with a 5x3 playgrid containing a fixed payline count of 5. All paylines in the Diamond Charge Extra slot game begin at the first reel and operate from left to right in adjacent reels. 

The visuals of the Diamond Charge Extra slot are simple, yet well-crafted, achieving a retro-style aesthetic through limited advanced designs. The backdrop features limited elements, with the focus seeming to be on gemstones, which is common for classic slot releases. Against the solid purple backdrop in Diamond Charge Extra, gemstones frequently travel, resembling shooting stars. 

Some other classic slot games that can be played here at BOYLE Sports include Wild Cash Machine and Clover Craze.

  • J
  • Q
  • K
  • A

In addition to the base game symbols mentioned above, the developers have also added wilds, collect, prize value, and jackpot symbols.

Diamond Charge Extra Bonus Features


Iron Dog Studios has added a selection of bonus mechanics to the gameplay of the Diamond Charge Extra slot. Wild symbols may land on any of the reels in the Diamond Charge Extra slot, potentially stepping in for any base game symbol to create or extend a matching combination if available.

The collector symbol can land only on the third reel in the Diamond Charge Extra slot, while prize symbols appear on the other reels. These precise value symbols may showcase a multiplier value ranging from 1x to 10x the stake, or even a title commonly found in jackpot slots, including mini, minor, major, and mega. The value of these jackpot titles is predetermined and can be found to the left of the reels. If at least 1 collector symbol and 1 cash symbol land on the reels in the same spin, the value of the cash symbol will be accumulated and awarded to the player.

If players land 4 or more cash symbols on the reels simultaneously with a collect symbol, the hold and win feature will be triggered. To begin this bonus, players will be awarded with 3 respins of the reels, where all base game symbols are removed, and only cash, collect, and blanks can land. During this bonus feature, any collect symbols that are landed will become sticky on the reels and will collect all cash symbols that land on the reels. Each time a symbol other than a blank lands on the reels, the respin count will be reset to its original value of 3. Once the respin count has depleted, the hold and win bonus will conclude.

At random in the base gameplay of the Diamond Charge Extra slot, the coin shower feature may be triggered. This bonus may be randomly triggered if players land at least 1 cash or collect symbol. If the feature is triggered, enough cash or collect symbols will be added to the reels to activate the hold and win feature.

Diamond Charge Extra Mobile Play


The Diamond Charge Extra slot features HTML5 software, which has been adopted into numerous UK online casino releases over the years for its cross-platform compatibility. All titles that implement this software can be played on a range of devices, including desktop PCs, laptops, tablets, and smartphones, when a stable internet connection is available.
