Santa's Wonderland Slot by Pragmatic Play

Five colored snowflake markers land on random grid positions every single spin. They sit behind the symbols, invisible until a winning cluster lands on top of one. Then the color determines what happens next. Blue clears the entire grid except wilds and refills it. Purple picks a random symbol and turns every instance of it wild. Yellow drops 2x2 blocks of matching symbols. Red goes bigger - 3x3, 4x4, or 5x5 blocks of the same symbol slam onto the grid. Green scatters 5 to 15 wilds across random positions. When multiple colors trigger on one spin, they fire in that exact order: blue first, green last.

The base game shares its 8x8 cluster pay engine with Gems Bonanza, wrapped in gold-framed holly borders and a purple winter backdrop stuffed with oversized gift boxes and ice crystals. Symbols are chunky Christmas toys - golden teddy bears, red biplanes, stockings, ornaments in blue and green, apples, and candy canes. An ornate clock sits to the right of the grid, and it tracks progress toward the main event.

That clock ties into the Midnight Riches progressive feature. Every winning symbol that disappears during tumbles adds a point to the meter. Hit 140 points from a single base spin's cascade chain and the bonus triggers. Level 1 plays all five spin modifiers once, in order, with a 3x multiplier on every win. Collect enough symbols to advance - 116 for Level 2 (6x), 120 for Level 3 (9x), 124 for Level 4 (12x), 132 for Level 5 (15x). The feature ends when you don't collect enough to move up, or after Level 5 finishes. At 100x your bet, the buy option skips straight to Midnight Riches.
