Threads of Ra Slot by Genii

Cascade wins on a 25-payline layout. That combination is unusual - most cascade games use cluster pays or ways-to-win, but Threads of Ra keeps the traditional line structure and layers tumbling reels on top. Winning symbols disappear, new ones drop in, and the cascade multiplier steps up through x1, x2, x4, x8. Not linear. Each step doubles the previous one, so the fourth consecutive cascade pays eight times what the first one did. The multiplier only resets when a cascade chain ends without forming a new win.

The Exploding Wild is what feeds those chains. When it lands, it destroys every adjacent symbol in up to eight surrounding positions, but leaves scatters and high-pay Egyptian symbols intact. So the phoenix bird, scroll, and sun disk survive the blast while the lower-tier feathers, ankhs, and chain links get cleared. New symbols fall into those gaps, and if they connect on any of the 25 lines, the cascade continues and the multiplier climbs another rung.

Free Falls trigger from the purple winged-heart scatter. Three give 8 rounds, four give 14, five give 20. During the bonus, a separate Extra Falls scatter appears exclusively on reels 2 and 4 - land both and you get 2 more rounds added. That restriction to just two reels keeps extensions rare. The cascade multiplier carries over between free falls, so a long chain early in the bonus builds the multiplier for everything that follows.

Warm metallic art style throughout. Red and bronze symbols sit against a golden desert backdrop with sun rays bleeding through from the upper left. Thread spools and woven fabric references weave into the Ra mythology motif - the name is literal, not decorative. A card gamble option appears after wins for anyone who wants to press the result.
