Light & Wonder's Jin Ji Bao Xi: Endless Treasure is the original Reel Ways base game from March 2019, not the BTG Megaways spin-off that came later. Same Chinese-fortune dressing (lacquered red, ornate gold dragons, phoenixes, tigers, turtles and koi over card royals 9 through K), same four-tier jackpot ladder strung across the top with gong, ingot, peach and orange icons. But the engine underneath is a 5-reel ways game with asymmetric strips of 3-4 rows, and the whole experience pivots around one button you don't see in many slots: the ALL UP selector.
Here's how ALL UP works. Before each spin you pick how many gold symbols to play, anywhere from 1 to 5. More gold means more ways open, the Fu Bonus coin values climb into higher tables, and the jackpot ladder swaps to a richer tier. It also costs more per spin. So the ‘strategy' is real in the sense that your math changes, but it's also just a fancy bet multiplier dressed up as agency. Honest moment: ALL UP feels strategic when it's really paying for a steeper ladder.
Wilds stick to the middle three reels and substitute for everything except the gold Fu Bonus coin. Land one on reel 3 and it can flip to a Gold Wild, doubling any premium-animal win it completes. Every Wild you land drops coins into the red lacquered pot above the reels, and on any spin where coins are added the hinged gold lid can swing shut. When it does? Twelve coins fan out across the screen, you tap to flip them, and three matching reveals lock in Mini, Minor, Major or the Fortune Grand. Pretty cinematic. One catch worth flagging: filling the pot LOOKS like it pulls the trigger closer, but accumulation does not affect the lid's odds. The progress is theatre.
Land 6 or more Fu Bonus coins and you reach the Feature Selector. Options 1-5 are Free Games variants seeded by how many gold symbols you were playing, with Yellow Coins subbing and pouring Fu values into the Shou meter (cashed at the end, plus three extra spins if 3+ Yellow Coins land mid-round). Option 6 is the Top Up Feature, a hold-and-spin where Bonuses lock in place over 6 spins. Yellow Coins pay their printed Fu value. Green Coins pay the running total of everything already locked, which is where the run-on wins explode. Fill all 15 coin positions and the Fortune Grand drops outright.
RTP sits at 95.65%, which is sub-96 and worth knowing before you commit. Volatility is high. Max win is capped at 15,499x your total bet plus whichever jackpot you might pop. Lantern-lit, opulent, occasionally cruel between bonuses, and the ALL UP layer gives Endless Treasure a personality the Megaways version genuinely doesn't have.
