Diamond Charge Hold & Win

Diamond Charge Hold & Win review

Diamond Charge Hold & Win mixes diamonds, gold coins and crackling electricity on a 5x4 grid with 30 paylines from Iron Dog Studio. The main event is a Hold and Win bonus: bonus symbols stick in place while respins run, and a Cash Collector, additive symbols and random multipliers can push the total up. Fixed jackpots sit on top of the coin values. Slotcatalog rates the volatility as medium-high and caps the maximum win at 5,000x, and you can also buy straight into the feature.
