Slot review: Mandalay Bay Riches

Mandalay Bay Riches is a glossy Las Vegas vacation in slot form. Play’n GO sets you outside the real Mandalay Bay style resort, with palm trees, gold trim everywhere, and that “high roller lounge” mood baked into every symbol. The gameplay is built around a simple idea that stays fun because it teases you constantly. Coins drop face down, chests start filling up, and you are always hoping the right vault moment shows up to flip everything into cash. It is not a complicated story slot, it is more like a steady treasure hunt where the big moments come from collecting the right coin types at the right time.

Slot overview: Mandalay Bay Riches

Mandalay Bay Riches uses a 5 reel, 3 row layout with 10 fixed paylines. The default RTP is 96.20%, but there are lower versions listed at 94.20%, 91.20%, 87.20%, and 84.20%, so you really should check the casino info panel. Volatility is high. The bet range is 0.10 to 50. The max win is 15,000x.

The core mechanics are Cash Collection with a Vault reveal, a Hold and Win bonus powered by three chests that can add modifiers, plus an Ante Bet option called GO Ultra that increases your stake by 50% for better feature odds.

Slot features: Mandalay Bay Riches

Cash Coins and Vault reveal: Coins can land face down with hidden values. If a Vault lands in the same spin as any Coins, the Coins flip and pay instantly. Regular coin values can award 0.25x to 50x the bet. Big Cash Coin prizes are fixed tiers: Mini 20x, Minor 50x, Major 200x and Grand 1,000x. When revealed, all coin values are added together and paid as a multiplier of your stake.
Three chest collection system: Some special Coins do not pay right away if no Vault is present. Instead, they are collected into one of three treasure chests, based on the icon on the coin. Each time you collect into a chest, there is a chance to trigger the Hold and Win bonus. It is possible to trigger the bonus with up to three chests active at once, which means up to three modifiers can be running in the bonus.
- X coin goes to the X chest.
- Arrow coin goes to the Arrow chest.
- Dollar coin goes to the Dollar chest.
Hold and Win bonus: Starts with 3 respins. Coins are sticky and remain locked once they land. Each time a new coin lands, the respin counter resets back to 3. The bonus ends when you spin and land nothing new for three spins. At the end, all visible coin values are added up and paid.
Hold and Win modifiers from chests:
- X chest modifier: adds an x2 multiplier that applies to prizes landing during the bonus.
- Arrow chest modifier: expands the playing area during Hold and Win.
- Dollar chest modifier: starts the bonus with a guaranteed Big Cash Coin.
GO Ultra ante bet: Can be enabled between spins. Increases your stake by 50%. In return, it boosts the chances of activating the game’s features.

Our verdict: Mandalay Bay Riches

Mandalay Bay Riches is built for players who like clean, classic cash collecting. The base game loop is easy to understand, and the Vault moments feel satisfying because you see a screen of hidden coins suddenly turn into real money. The Hold and Win bonus is the main chase, and the fact that you can bring in more than one chest modifier gives it more personality than a basic respin feature. The downside is that it can feel repetitive if you want lots of different bonus types, and high volatility means you can go through quiet stretches while waiting for the right collection run.

Our rating 3.5/10
