Bigger the Loot: Chamber of Riches Slot by Light & Wonder

The reels sit inside a dragon's lair, with a horned red dragon coiled atop a mountain of gold coins, glowing dragon eggs perched on stone outcrops behind the grid. The five reels themselves play out against a deep crimson backdrop trimmed in burnished gold, with crowns, gem-filled satchels, spell scrolls, potion bottles and royal cards (A through 10) for the lower tier. Despite the "heist" naming convention of the Light and Wonder Bigger the Loot series, Chamber of Riches leans hard into fantasy hoard imagery rather than vault-and-security iconography.

Six or more Gold Coin symbols land on the grid and the bonus opens with three respins. Every new coin landing locks in place and resets the counter back to three. The grid expands from three rows to six during the feature, so there's a lot more real estate to fill. Each coin shows a cash value pulled from one of two pools: the standard pool spans 0.10x to 0.30x bet across seven possible values, and a rarer "additional" pool stretches from 0.30x all the way to 2x bet. So a single high-pool coin can carry as much weight as ten low-pool ones.

The mechanic that separates this entry from its sibling Majestic Bounty is the Value Increases system. Certain trigger events during the bonus pump up the values already showing on locked coins, in increments of 20, 40, 60, 80 and so on up to 200 cents. Coins you locked early can grow several times over before the respins run out. That's the route to the four-tier jackpot ladder, with the TOP prize capped at 2,500x.

For anyone unwilling to wait on a natural six-coin trigger, the Buy Pass costs 50x and drops you straight into Hold-and-Spin with the six-coin minimum already met. That's notably cheaper than most premium L&W feature buys, which tend to sit between 100x and 200x. Combined with the wide bet ceiling (up to $1,600 a spin), it's clearly aimed at players who want the bonus and don't want to grind for it.
