Buildin' Bucks Slot by Play'n GO

Three material tiers control everything. Wooden frames pay 2x-5x when they break. Brick frames pay 6x-12.5x. Gold frames pay 15x-25x. The gap between tiers is steep, and the entire bonus structure - respins, free spins, the Feature Wheel above the reels - exists to place frames on the grid and, ideally, upgrade them before the Leprechaun shows up to demolish the lot.

A Bonus Scatter on reel 3 spins the Feature Wheel, which picks one of six results: a respin set tied to one of the three builder characters, or a fixed prize (30x, 50x, or 100x). Each builder works with their own material. Woody Elf's respins start with 3 wooden frames, Grout Bricky gets brick, Fairy Mary gets gold. All three give 6 respins and rely on Hard Hat Scatters to fill empty positions with new frames. If every spot on the grid fills with gold frames and one more Hard Hat drops in, the game pays 100x on the spot. Free spins trigger separately from 3+ Hard Hat Scatters and always award 6 spins, but the number of triggering scatters sets the starting frame tier - 3 gives wood, 4 gives brick, 5 gives gold. Inside free spins, Hard Hats don't just add frames. They upgrade what's already there. Wood becomes brick, brick becomes gold. A retrigger wheel inside the bonus can add up to 5 extra spins per activation, capping at 50 total.

The construction-site theme leans more enchanted forest than hard hat zone - carved wooden card symbols, character animations that actually have personality, and a wrecking-ball Leprechaun riding his pot of gold at the end of each bonus round. The sequel, Buildin' Even More Bucks, pushed the max win to 7,500x and added a Double Wheel. This original caps at 5,000x with no buy bonus option.
