Happy Dragon Slot by Pragmatic Play

Two extra reel positions sit below the diamond-shaped grid, and they control most of what this game pays. Multiplier Reel 1 spins blanks, x2, x3, or x5. Multiplier Reel 2 adds x10 to that range. Both land a value? They multiply together - so x5 paired with x10 means every line win on that spin gets a 50x boost. The base paytable is built around this. Six symbols, premium gold ingot paying 5x for three of a kind, lowest symbol at 0.2x. Tiny numbers on their own, but a 0.3x hit with a 50x multiplier behind it turns into 15x.

The expanding wild lands only on the center reel and fills the entire column when it appears. On a three-reel layout with 10 paylines, a full wild column connects every symbol on reel 1 to every symbol on reel 3 through every active line. That same wild also doubles as the free spins trigger - no scatter exists. When it hits, there's a random chance it fires off 5 free spins, roughly once per 120 base game spins. Three buy options let you skip the wait at 4x, 4x, and 8x your bet.

Those 5 free spins lock the center reel as a permanent wild for the entire round. Every spin guarantees full payline coverage through the middle. The bigger shift is Multiplier Reel 2 gaining a x100 value, pushing the combined multiplier ceiling to 500x per spin. Dead spins are impossible with the locked wild, though a blank multiplier reel still produces minimum payouts. Whether the bonus round pays 20x or climbs toward the 5,000x cap depends entirely on that x100 landing. Fat Panda built this the same way they built Lucky Tiger - compact grid, Chinese theme, high hit frequency masking high volatility through a low base paytable that only pays properly when the multiplier mechanics line up.
