Joker Catcher Slot by Gamzix

Catch Frames are the mechanic that separates this from Gamzix's Hold the Spin series. Each spin randomly highlights 4-5 positions on the grid with glowing golden borders, and only symbols landing inside those borders activate their special effects. Diamonds, jackpot diamonds, wheel symbols, bonus badges - all of them do nothing unless they hit a lit frame. Regular symbols (the red-gold 77s, dice, bells, metallic card royals) pay normally on the 11 paylines regardless. So every spin is two games at once: a standard payline evaluation plus a lottery for what lands inside the frames.

The Joker sits permanently locked in the center position. It works as a Wild for payline wins, but its real function is collecting. When a diamond hits a Catch Frame, the Joker grabs its value - anywhere from 1x to 15x your bet - and adds it straight to the win. Jackpot diamonds work the same way: land one on a frame and it reveals Mini (25x), Minor (50x), Major (150x), or Grand (1,000x). The Wheel symbol, when it hits a frame, spins a secondary wheel that awards either a cash prize, a jackpot tier, or a Bonus symbol.

That Bonus symbol is where things compound. Landing one on a Catch Frame during the base game starts the bonus round with 6 frames per spin instead of 4-5, and only special symbols appear - no regular pays cluttering the grid. Each additional Bonus symbol inside the round adds 2 extra spins, 2 more Catch Frame positions (up to 14 total), and upgrades every jackpot value by its initial amount. So after two Bonus symbols, Mini sits at 75x instead of 25x, and Grand hits 3,000x. Four Bonus symbols is the cap - Grand at 5,000x, every other tier tripled alongside it.

Deep blue diamond-check background behind the gold-bordered vertical grid, white-blue diamond symbols with gold-etched values floating over red dice and chunky double-7s. The jester in the center wears a red-and-yellow pointed hat with that permanent grin, and the four jackpot meters stacked along the left edge pulse in green, blue, orange, and red.
