Diamond Cascade

Pragmatic Play sets Diamond Cascade on a planet made of gemstone, with shards of rock jutting out of the ground across a 5x5 grid of 50 paylines. Matching symbols on an active payline pay left to right, and eleven pay symbols of varying cut and colour fill the paytable, paying between 0.6x and 20x the bet for five matching icons. A wild appears on every reel and substitutes for any of them.

What separates Diamond Cascade from a standard payline slot is the Color Tumble mechanic layered on top. After a paying combination lands, any group of five or more symbols sharing the same background colour — connected vertically or horizontally anywhere on the grid — explodes away regardless of whether that group itself formed a line win. The symbols above fall to fill the gaps, and the process repeats for as long as a qualifying colour cluster remains on screen.

Every symbol removed this way feeds a meter, and each block of 20 collected symbols adds one to a win multiplier that applies to every payline win on the following spin. In the base game that multiplier resets once a new spin begins, but during the free spins round it carries over and keeps climbing for the length of the bonus instead of resetting between spins.

Landing three or more free spins scatters awards 15 free spins, and further scatters during the round add more: three, four or five landing at once grants an additional 5, 10 or 15 spins respectively. Free spins can also be bought outright for 100 times the bet, which guarantees three, four or five scatters land on that spin to open the round immediately.

Diamond Cascade runs at a high volatility with a base RTP of 96.06%; an Ante Bet configuration that raises the stake by 25% for better odds of triggering the bonus pays 95.12%, and the version reached through the buy-feature option returns 93.98%. Bet size ranges from 0.20 up to 240, and the maximum win is 8,000 times the stake. It was released on 30 July 2023.
