Developer Purple Diamond is a casino slot from 3 Oaks Gaming released in March 2026. It uses a classically styled 5x3 layout with 20 paylines and centres on the expanding reels mechanic, alongside a Hold & Win bonus round. The game includes a purple Diamond collect symbol and a blue Orb bonus symbol, with the bonus also able to start from the Diamond progress metre or the Lucky Spin feature.
When six bonus and/or collect symbols land, the bonus game begins with four spins. During this feature, only bonus and collect symbols can appear. Some bonus symbols may carry fixed Mini, Minor or Major jackpots. The round starts with three locked rows, each tied to its own progress metre, and collect symbols unlock these rows from the bottom upwards while adding one extra spin.
Once a row is unlocked, the top row can introduce Super Collect symbols, which add two more spins and absorb symbols beneath them. A Super Collect symbol may also award the Grand Jackpot. This demo version lets players play for free and practice before playing for real money.
