Mahjong Riches Slot by Spadegaming

Spadegaming built this one around a quirk most slots get wrong: the Wild doesn't exist on the reels. It can't drop in, can't appear in a stack, can't show up as part of a near miss. The only way a Wild enters the grid is through Caishen, the Chinese God of Wealth perched in the top-right of the playfield - he periodically reaches down and converts existing symbols into Wilds. Take Caishen out of the picture and you're playing a strictly natural-symbol game on a 6-reel 3-4-5-5-4-3 board with a permanent 3,600 ways count that never shifts, since the layout is fixed rather than a Maxways-style variable grid.

The reels themselves are designed to look like an actual mahjong table, vivid teal felt with red trim, and the symbols are real mahjong tile faces - Wind tiles (東南西北 carved in blue and red), Dot tiles, Bamboo sticks, character tiles - each one rendered with the cream and ink-colour look you'd see at a live game. Behind that sits a gilded palace interior, copper pillars wrapped in golden dragons, with piles of square-holed coins stacked in the foreground.

Wins cascade. Symbols in a winning combination clear, new tiles drop, and a multiplier ladder runs along the top of the grid in base play: x1, x2, x3, x5. The x4 step is deliberately skipped, which is unusual - most cascade ladders climb in even increments. Once you reach x5 it locks there until a non-winning cascade resets you back to x1.

The free spins triggers are where Spadegaming gets clever. Three red mahjong Scatters anywhere trigger the standard Free Game - that's a lower threshold than the usual four-scatter requirement and it makes the bonus genuinely reachable. The Special Scatter, a purple tile that only lands on reel 6, opens the second door: hit two red Scatters plus one Special and you go into the Caishen Free Game instead, which runs 10 spins on a stripped-down symbol set of high-value tiles plus Wilds, so the hit rate on big-paying combos is much higher than the standard variant. Both modes feature a Dice symbol that only appears during free spins and reveals 1-6 extra spins each time it lands.

Two Buy Bonus tiers sit beneath the reels: 50x your stake for the regular Free Game, 100x for the Caishen Free Game. The Wild substitutes for everything except the two Scatters and the Dice, which keeps the Caishen feature mathematically distinct from the natural reel set. Max win caps at 9,000x.
