Mandalay Bay Riches

Mandalay Bay Riches is an exclusive release from Play'n GO built around a Las Vegas resort theme, running on a 5-reel, 3-row grid with 10 fixed paylines and a Hold & Win bonus at its core. It brings together cash-collecting coins and collectible chests in a structure that will feel familiar to fans of the wider cash-collect genre.

The presentation leans on recognisable Las Vegas imagery, palm trees, gold accents, and the Mandalay Bay resort itself anchoring the backdrop, giving the game a clean, easily readable style. It sits closer to a traditional slot design than some of Play'n GO's more experimental releases, favouring clarity and familiarity over visual flair.

Gameplay revolves around Cash Coins, which either reveal their value immediately via Vault symbols or get stored away in chests that can eventually trigger the Hold & Win bonus. Big Cash Coins pay fixed jackpot-style prizes and can climb in value incrementally before being collected, adding a bit of building tension to the base game as coins accumulate. Once the Hold & Win bonus triggers, it plays out as a respin feature that can be boosted by reel expansion, a global multiplier, or an instant Big Cash award, giving the round a few different ways to build toward its ceiling.

On the numbers, the Mandalay Bay Riches RTP sits at 96.2%, a solid figure, and the game is rated high volatility, with a max win of 15,000x the stake giving the Hold & Win round a genuinely worthwhile ceiling to chase. Betting runs from 10p/c up to £/€50 per spin. There's no bonus buy or ante bet option available, so the pacing relies on the base game's Vault activations to keep things moving between Hold & Win triggers.

Mandalay Bay Riches offers a steady, traditional take on the cash-collect format, built for players who enjoy the predictable structure of coin-collecting and Hold & Win bonuses over more experimental modern mechanics. It's a comfortable, well-constructed slot for fans of the genre, even if it sticks closely to a tried-and-tested formula rather than breaking new ground.

The escalating Big Cash Coins are the base game's main source of tension, since watching a fixed-value prize climb before it's finally collected adds a bit of drama to otherwise straightforward spins. Once the Hold & Win round does trigger, the mix of reel expansion, global multipliers, and instant Big Cash awards gives it enough variation to stay interesting across repeated attempts, even without a bonus buy option to speed up the wait between rounds.

The demo is free to try at johnessyslots before playing with real money, giving a good sense of how often the Vault symbols activate before deciding whether the pacing suits you.
