Stones of Magic Slot by HeronByte

Cascading wins drive everything here. Each avalanche in a round bumps the multiplier up one step through a fixed ladder - x1, x2, x3, x5 in the base game. Land a winning combo, the symbols shatter, new stones drop in, and if those form another win the multiplier climbs again. Four consecutive cascades in one spin reach the x5 cap. It resets on your next spin.

Free spins flip that ladder to x3, x6, x9, x15. Ten spins awarded when three scatter symbols land in succession from the leftmost reel along one of the 20 paylines. Not anywhere on the reels - they need to sit on consecutive positions of the same betline starting from reel one. That is a stricter trigger than most tumble slots use, where scatters typically just need to appear anywhere. Retriggering is possible during the bonus.

A silver-haired fairy stands beside the grid against a lush enchanted forest lit by golden-green rays. The symbols are diamond-shaped stone tiles with celtic knot borders. Four high-pay stones represent elements - a blue water crystal, red-orange fire gem, green earth stone, and teal air symbol. Three ornamental low-pay stones fill out the rest with spiral and knot designs. Wilds here adopt the appearance of whichever symbol they substitute for, turning into elemental or ornamental variants depending on the winning line.

After any win you can risk it in a gamble round. Standard double-or-nothing. The fantasy aesthetic is polished for a smaller provider - Spine animations on the fairy character and smooth cascade transitions give it a more expensive feel than the basic 20-line structure might suggest.
