Jewels of Prosperity Slot by PG Soft

Everything in this game funnels toward one question: which symbol gets chosen at the start of free spins? Three or more scatters anywhere on the six reels trigger 7 free spins, and before the first bonus spin lands, the game randomly selects one regular symbol - any pay symbol except the Wild and Scatter - to be the "special symbol" for the entire round. From that point on, every instance of that chosen symbol landing on reels 2 through 5 transforms into a sticky Wild that stays locked in place until the feature ends.

The snowball effect is the point. Spin one might convert two or three positions. Spin two adds more. By spin five or six, reels 2 through 5 can be half-covered in sticky Wilds, and every new spin drops fresh symbols into whatever positions aren't already locked - meaning fewer empty spots and denser winning combinations each time. If the game picks a high-frequency symbol as the special one, the grid fills faster. Pick a rare premium and you get fewer conversions but higher base payouts from the Wilds substituting into premium-value lines. And +1 Free Spin symbols extend the round, giving the sticky Wilds more time to accumulate. No retrigger in the traditional sense, just these individual +1 extensions that keep the chain going spin by spin.

Deep forest greens and rich golds set the backdrop, with traditional Chinese prosperity motifs across the symbols - a Ruyi sceptre, a Kylin lock, dragon and phoenix carvings, all rendered in that polished jade-and-gold palette PG Soft uses for their imperial themes. The base game is straightforward: 4,096 ways, Wilds on the four center reels substituting for everything except Scatter, no tumble mechanic, no buy option. The free spins hit rate sits around 1 in 208 spins, with roughly 28% of the total return concentrated in that single feature. When it lands, the gap between a forgettable round and a grid full of locked Wilds comes down to that one random symbol pick at the start.
