Diamond Cascade Slot by Pragmatic Play

The Color Tumble mechanic sets this apart from standard cascading slots. Wins still form across 50 fixed paylines, but after any winning spin, the game checks for clusters of five or more symbols sharing the same background color - adjacent horizontally or vertically anywhere on the grid. Those clusters explode, remaining symbols drop to fill gaps, and new symbols fall in from above. The tumble continues until no qualifying background clusters remain.

Every 20 symbols removed through Color Tumbles adds +1 to a win multiplier. In the base game, this multiplier resets after each spin completes. During free spins, it carries across the entire bonus round without resetting - a key distinction that drives the bonus potential.

Three or more diamond scatters trigger 15 free spins. Retriggers award 5, 10, or 15 additional spins for 3, 4, or 5 scatters respectively. The persistent multiplier combined with repeated tumble chains can compound significantly across a long bonus session.

The Ante Bet increases your wager by 25% for improved scatter frequency. Buy Free Spins is available at 100x. The gem symbol set features diamonds, rubies, emeralds, amethysts, and topaz stones against a crystal cave backdrop.
