Bubblin’ Riches: Slot Overview

Every so often you spin a slot and get that nagging sense you’ve been here before, without being able to place it—like waking up with the remnants of a great dream that slips away as you try to recall it. With Play’n GO’s aquatic Bubblin’ Riches, it took a moment for the connection to click: the Egyptian-themed Tomb of Gold 2. The maths and features match up, but the completely different theme and styling try hard to disguise it. Where Tomb of Gold 2 leaned into a darker, ornate Egyptian mood, Bubblin’ Riches goes for a bright, breezy ocean vibe—though beyond that, there isn’t much separating them.

In the same upbeat spirit as Yggdrasil Gaming’s Golden Fish Tank slots, Bubblin’ Riches is relentlessly cheerful—almost like an online slot dreamed up by the people behind Finding Nemo. Soft blues dominate the screen, making it easy to imagine you’re snorkelling around a Caribbean island (or any warm-water paradise you prefer), watching bubbles drift lazily upward after a deep breath. The tone is friendly and soothing, as if these adorable sea creatures couldn’t possibly be out to take anyone’s money. Naturally, it’s still a slot, and it still plays for keeps, no matter how charming the underwater setting looks.

Crystal-clear, like peering into a fishbowl perched on the TV, Bubblin’ Riches’ play area uses 6 reels, 4 rows, and 4,096 ways to win. The volatility rating is high, and the top RTP is Play’n GO’s familiar 96.2%, with four lower versions also in circulation. Bets range from 10c to $/€100 per spin in the base game.

There are nine paying symbols swimming through the reels: 10-A card ranks, followed by blue, green, purple, and yellow fish. Card wins, formed with 6 OAK, return 1x to 1.4x the bet, while the fish pay 3x to 5x for 6 OAK. Wilds appear on every reel, replacing any standard pay symbol, and they pay 6x for a winning line made up of 6 wilds.

Bubblin’ Riches: Slot Features

The feature set is familiar territory, featuring Coin symbol prizes, a Lock’n Gold round, and free spins with an increasing multiplier.

Goldfish

When 5 or fewer Coin symbols land, they are collected by the Goldfish above the grid. If 1 or more Coins are collected, the Goldfish can potentially trigger the Mini, Minor, Major, or Grand prize worth 20x, 50x, 100x, or 1,000x the bet, respectively. The Goldfish’s size is only a visual touch and has no impact on how likely the feature is to trigger.

Lock’n Gold

When 4 or 5 Coins land, the reels without Coins on them respin. Landing 6 Coins triggers the Lock’n Gold feature. where 3 respins are awarded and Coin symbols stick on each spin. Respins reset when at least 1 Coin lands. Filling the screen with Coins awards a flat 500x total, no matter what values the Coins show.

Reward Spins Bonus

Landing 3 or more scatters activates the Wheel Bonus. The number of scatters that trigger it determines which different segments of rewards appear on the wheel. If the bonus is started by 3, 4, 5, or 6 scatters, players can win 10-30, 15-30, 20-30, or 25-30 free spins, respectively. A starting multiplier of x1 to x5 is also granted. During free spins, x1, x2 and x3 wilds can land; when they do, they add +1, +2, or +3 to the multiplier counter, which applies to all wins in Reward Spins. Each scatter that lands adds +1 free spin, while Coins are not part of the feature.

Bubblin’ Riches: Slot Verdict

On the plus side, Bubblin’ Riches is a fish slot that isn’t trying to mimic the Big Bass titles or the Fishin’ Frenzies. Whether that was ever a key goal for Play’n GO is debatable, though, since Bubblin’ Riches is essentially a reskin of Tomb of Gold 2. That earlier game was generally well received, and its strong visuals created an appealing Egyptian backdrop. Bubblin’ Riches, by contrast, feels much lighter (and a touch more generic), fitting neatly into the style of slots that portray the ocean as a single bubbly, happy ecosystem—no predators, smiling fish, and a world that’s carefree rather than packed with stress, bills, and worries. In that respect, it could be a soothing getaway for the right kind of player.

Much of Bubblin’ Riches revolves around collecting Coins for the crowned Goldfish above the reels—though “busywork” might be the more accurate description, since most of the time it doesn’t actually lead to anything happening. Coins float up, Coins set off respins, and they keep the screen lively, even if they don’t always translate into extra cash. Every now and then, though, they can spark something worthwhile—ideally the Grand prize or a full grid during Lock’n Gold. The Grand prize is fairly restrained at 1,000x, but add one more zero and you reach Bubblin’ Riches’ 10,000x maximum. Clearly, the jackpot prizes and hold ‘n’ win action won’t carry the whole experience on their own, which means free spins need to do the heavy lifting. It could happen—there’s a climbing multiplier on a 4,096 ways to win setup, and stranger things have happened at sea, as they say.

By the time the underwater trip is over, Bubblin’ Riches feels noticeably less thrilling than Tomb of Gold 2, mainly because the setting is less intense and, of course, because it’s a reskin. Still, its relaxed, easygoing mood may be exactly what some players want when they’re looking to switch off for a while—assuming the gameplay clicks.
