Rainbow Gold Slot by Pragmatic Play

A scrolling prize tracker runs across the top of the grid, one item above each reel. Every spin, the leftmost prize drops off and a fresh one slides in from the right. Values range from 2x up to 100x your bet, but two special items rotate in as well: ALL IN VIEW, which collects every tracker value on screen at once, and Super Spins, which kicks off the free spins round. The catch is that none of these prizes do anything on their own. You need a Leprechaun symbol to land on a reel to grab whatever's sitting above it.

That collection mechanic is the entire base game loop. No scatter count, no bonus symbol accumulation - just the tracker cycling and Leprechauns appearing when they feel like it. Change your bet level and the tracker state resets, so there's a strategic element to sticking with one stake. The ante bet bumps your wager by 25% and increases Leprechaun frequency, though the max win drops from 5,000x to 4,000x when it's active. Wins still reference your original stake, not the inflated amount. At 100x total bet, the buy option forces a direct entry into Super Spins.

Super Spins play across up to four separate 5x3 grids simultaneously. The tracker item you collected determines how many matrices unlock - anywhere from one to all four. Each grid runs its own independent tracker with boosted prizes: values up to 500x, a SUPER ALL IN VIEW that sweeps prizes from every active grid, RAINBOW BOOST to unlock a locked matrix mid-round, and extra spin awards of +2, +3, or +5. Eight starting spins with retriggering built in. The visual payoff of watching four grids spin together against that mossy Irish forest backdrop, each with its own tracker cycling overhead, makes the bonus feel dense in a way most free spin rounds don't.

Deep green felt, ornate Celtic knotwork on the reel borders, golden clovers and frothy beer mugs as the premium symbols. A cheerful leprechaun in a bright green top hat leans into the right side of the screen. Treasure chests above the reels hold the tracker prizes, linked by a painted rainbow arch that glows brighter during bonus rounds.
