Only Coins Slot — Online Slot Review & Free Demo

Only Coins Slot Review: Bonuses, Features & Free Demo

Only Coins is a unique online slot launched by Gamzix in 2025, which offers fixed jackpots and a potential payout of up to 2,000x your bet. This 3-reel, 3-row online slot game features bonus rounds with re-spins and, as its name suggests, only features “coin” symbols, which are a type of money symbol with varying values based on bet size. In this Only Coins slot review, we’ll tell you everything you need to know about this unique Gamzix slot! 

Only Coins Gameplay: What to Expect?

We often review games where base game payouts are low, whilst having extremely profitable bonus rounds, but Only Coins builds on this foundation and takes it to the next level.

You can expect zero profits during the base game, but bonus rounds that come much more frequently than in other slots to compensate. 

What Makes Only Coins Unique?

Although this slot does feature a “base game”, its sole purpose is to trigger the special rounds, which is where you can actually earn money. Considering that coin symbols may have values of 1x to 9x, this game doesn’t feature low payouts. At the very least, you’ll get 3x your bet, but it’s likely that you’ll get much more than that, depending on your luck.

We’ve never played any slot like this. It’s a very unique concept, in our experience. 

Bonus Features, Bonus Gameplay & Special Features

This game is called “Only Coins”, and it really does justice to its name. There are six types of symbols, most of which only appear during the special bonus rounds. During the base game, you’ll see three symbols:

• Coin symbols: they may be worth anything between 1x to 9x your bet, but they don’t pay during the main game. You need to land three in the center row to trigger the bonus round.
• Mystery symbols: they appear during the main game, but stay locked in place until the bonus game is triggered. They will remain there until the end of bonus rounds, revealing a value from 1x to 9x your bet (like a Coin symbol) or any of the fixed jackpot symbols.

It sounds complicated, but it’s really very simple. We picked up the pace of the game in just a few spins, and we’re sure you’ll do it too. 

We’ll tell you more about the game’s main special features shortly, but there’s one aspect about them that we really like: it comes with a bonus buy feature, which lets you pay 30x your bet to move directly into the game’s special round. 

Bonus Rounds

Collect three coin symbols in the center row to trigger bounds rounds that kick off with 3 respins, where the values of all coin symbols appearing on the reels add up and are paid out at the end of the round. Each time a symbol appears on the reels, the respin counter resets to three. 

These rounds have a couple of additional features to look out for:

• The Walking Multiplier Frame: Doubles the value of any symbol it covers. If paired with a Collect symbol, it first collects all values and then doubles the total.
• Special Collect Symbols: Collects all visible values from Bonus, Mystery, Jackpot, and other Collect symbols across the grid when it lands, helping you earn massive payouts. 

Heap of Coins Feature

Whenever a symbol lands on the reels during the base game, it may trigger the Heap of Coins feature, which ensures that enough symbols are added to trigger the bonus round. 

This feature is part of the reason why this game only features medium volatility while having such a low hit frequency: it allows you to randomly access the game’s special rounds at any given time. 

RTP, Hitting Frequency & Volatility

The game features a medium volatility and a standard return rate, but gameplay is probably very different to what you’re accustomed to. These are the main attributes of this online casino game:

• RTP: 96.00%
• Hit Frequency: Undisclosed.
• Volatility: Medium

Best Only Coins Alternatives

Only Coins is quite a unique game, delivered by a studio that truly knows how to think outside of the box. If you’re keen to try out other Gamzix slots, we can recommend a couple of alternatives that feature more traditional slot gameplay but combine it with unique bonus rounds.

Tiger Pot: Hold the Spin

Tiger Pot: Hold the Spin is one of our favorite Gamzix slots. It also features respin rounds with symbols that stay locked in place, but it comes with a base game much more akin to that of a classic slot game. It also features a much larger potential payout than Only Coins, standing at 10,000x your bet. 

Book of Zulu

Book of Zulu features a max payout of 2,500x and an option to pay a little extra to ensure a wild symbol on every spin. We’ve been playing a lot of Gamzix slots and even made a list of our favorites.
