Only Coins Review

Coins of gold attract players and Gamzix, an ambitious and capable game developer knows that perfectly. After Sunny Coin and Coin Win, and several other games with Coins on their reels, the studio has decided to change the concept. In April, it launched its first game paying only during the Bonus Game - Only Coins slot.

It comes with fast-spinning reels, an innovative Heap of Coins feature, a bonus round, and 4 fixed jackpots. Of course, the provider has hidden several other surprises that I’ll reveal in this review article. You can run down a test right away via the Only Coins free play mode linked above and see how mesmerizing those pieces of gold can be!

Gamzix – Game Provider

Gamzix is a rather young studio with huge potential and resources. It was founded in 2020 but already has more than 60 games, including the Only Coins online slot. Gamzix is a Maltese game provider, and constantly challenges casino enthusiasts with new features, refined visuals, and high payout rates.

Slot Theme And Storyline

The Only Coins slot has no complex script behind and the active zone stands in front of a city reminiscent of Las Vegas. Tall buildings stand as hotels and casinos, carrying gambling-related names like “Fortune” and “Lucky”. The backdrop is colored in nice blue nuances that go easy on the eyes and make the contrast with gold elements even nicer.

The Coins theme is well-utilized, although the symbols look a bit more like casino chips. Still, there are plenty of coins on top of the reels, and with every spin they multiply. All controls are on the right and four jackpots, along with the Only Coins Bonus Buy button are placed on the left. Graphics and animations are of the finest quality, while the soundtrack is lively and pleasant.

Only Coins Slot Rules And Gameplay

The Only Coins game has a classic 3x3 grid with no paylines. The gameplay is pretty straightforward - land 3 symbols of any type on the middle row or “active row” to activate the bonus game. It all comes to that because the sweet payouts are distributed there. You can use Autoplay, Fast Play, and Turbo Play to make your play more delightful.

The Only Coins slot has 42 stake levels players can choose from. The minimum bet is €0.10, while the maximum is €100 per spin. There are plenty of wagering strategies that can be used in casino games like that and the bonus triggering frequency is usually very high. There are 2 other ways to activate the bonus - Heap of Coins and Buy Bonus.

Symbols And Paytable

As I already mentioned, there are no regular symbols here, but before continuing with the Only Coins slot review, I wish to clarify a few other details. The game features sticky symbols, which are active in the base game, too. However, the values of Bonus Coins are irrelevant in this stage and they land only to trigger the payout mode!

Otherwise, these are a few steps you need to take, but don’t worry the process is simple and usually, quite intuitively organized.

Only Coins Bonuses And Special Features

Given the lack of regular payouts, all the Only Coins slot action is reserved for the bonus. The minigame is well-organized and more than one bonus feature is waiting for you there. You can win a hefty cash prize and why not unlock the jackpots? Here are all the special features and mechanics:

Mystery Symbols & Collect Symbol

Only Coins is loaded with two types of Mystery Symbols. Sticky Mystery may land in the base game and bonus round and remain in their position until a bonus minigame is completed. At its end, each of these symbols reveals a cash reward from 1x to 9x the bet, or one of the following jackpots: Mini, Minor, or Major. Mystery Jackpot may appear during the bonus game and will reveal one of the mentioned jackpot prizes.

Cash Collect is another special symbol that can appear only in the bonus minigame. Whenever it does, it collects all prize values from the symbols in view, including jackpots and other Cash Collect values. This symbol can cause an early reveal of Sticky Mystery symbols in order to collect their values.

Heap of Coins

Heap of Coins is a Symbols Collection mechanic that has the power to randomly activate the Bonus Game. All Coins and other bonus symbols, except Sticky Mystery, that land in the base game will be collected in the pile on top of the reels. That will happen in non-winning spins only! At the time of a collection, Heap of Coins may trigger randomly and add bonus symbols of different types on the active row to activate Bonus Game.

Bonus Game

The Only Coins bonus round starts with 3 bonus symbols on the active row or via the Heap of Coins feature. When it does, the triggering symbols stick on their positions until the end of the minigame. It’s actually a variant of Hold & Win and players get 3 respins to find more bonus symbols. On each successful landing, the counter will be reset back to 3.

Only Coins by Gamzix is packed with 4 jackpot prizes listed below. Three of them, Mini, Minor, and Major, can be won multiple times via the Sticky Mystery or Mystery Jackpot symbols. Grand Jackpot is awarded if you complete the grid and end the minigame with 9 symbols in place.

During the bonus, a special Walking Multiplier Frame is active. It switches position on every respin and holds a multiplier of x2. The feature has the power to double the size of any cash prize or jackpot upon landing on it. Walking Multiplier Frame can boost the same price multiple times.

• Grand Jackpot - 500x the bet
• Major Jackpot - 50x the bet
• Minor Jackpot - 20x the bet
• Mini Jackpot - 10x the bet

Buy Bonus

Buy Bonus is a useful tool that awards the Bonus Game immediately against a rather low price of 30x the bet. The RTP rate does not change if you use the functionality. However, the feature might not be available in some countries or online casinos. It might be also limited and disabled above a certain bet threshold.

Only Coins RTP, Volatility And Max Win

The Only Coins RTP ranges and at its highest, the rate is 96.02%, which combines perfectly with the medium levels of volatility. The bonus triggering frequency is officially unknown, but my tests showed that it should be between 1 in 30-50 spins. The alternative payout rates are 95.02%, 94.02%, and 92.03%, but I recommend avoiding these variants. The Only Coins max win is 2,000x the bet or up to €200,000, which is neither bad nor impressive.

Only Coins Demo Version And Free Play

If you are looking for free play, SlotCatalog has an Only Coins demo available on this page. The access is 24/7 and you can easily test strategies or simply have fun with the spinner. The free demo will also help you decide whether to continue with the real money version or not. We also have an excellent selection of verified casino sites!

Play The Game On Your Mobile

Only Coins is an HTML5 slot and is compatible with all operating systems, browsers, and platforms. There is no mobile app that has to be downloaded, but I will recommend a software update for optimal performance. You can play Only Coins game on Android and iOS devices in both landscape or portrait modes.

Strategy & Tips For Winning

As usual, Gamzix provides players with plenty of betting options for them to develop a decent Only Coins strategy. However, that might not be the wisest approach since the game only pays during its bonus. I can’t say which strategy will deliver the best results as it depends on your taste for risk. Here are some tips that will help:

• Test different approaches and systems via the Only Coins free play mode
• Sign in at reputable casino sites only with valid licenses
• Look for suitable bonuses to play the Only Coins slot machine
• Keep your head cool and don’t let emotions dictate your play
• Decide on a budget and stick to it no matter the current results

The 200 Spins Only Coins Experience

Only Coins is truly straightforward and I completed my 200-spin test session in several minutes. Keep in mind that the machine can easily drain your account, so bet smart! I managed to activate the bonus 4 times with the following outcomes: 35x, 98x, 47x, and 51x the bet. I ended the session with a 27% profit, which is marvelous!

Pros And Cons Of Only Coins Online Slot

Similar Slots To Try

If you like Only Coins by Gamzix, please take a look at the following alternative slots offering similar gameplay and features:

• 12 Coins Grand Diamond Edition - a highly volatile slot with an RTP of 96.14% and a max win of 5,000x. It comes with a 4x3 grid, 4 jackpots, and a Chance Level feature. Hold the Jackpot is enhanced with special symbols, but the base game also offers Cash Out labels.
• 15 Coins Grand Platinum Edition - a 5x3 grid with bonus payouts only, a 2,500x the bet max win, and a payout rate of 96.17%. The Platinum Edition offers Cash Out, Cash Infinity, Mystery, Jackpot Mystery, and Chance Level features.
• 36 Coins Grand Gold Edition - a brand-new slot crafted once again by Wazdan with bonus payouts only, but on a 6x6 grid. As usual, you can choose the volatility and activate Chance Level. The slot offers Cluster Collectors, Sticky to Infinity, Cash Infinity, and Hold the Jackpot.

Final Thoughts

In conclusion, the Only Coins slot uses mechanics that we have already seen in games launched by top providers, like Wazdan. Therefore, that is no innovation, but it’s definitely an interesting step aside from Gamzix. This type of slot excludes the usually small base game payouts and in return provides a more frequent bonus minigame.

However, that can also make a slot more boring and less attractive for a huge group of gamblers. Only Coins is packed with a dynamic bonus with plenty of features and special symbols, but only 9 possible prizes. I’ll leave the final decision to you and once again recommend playing the Only Coins demo before staking real money!
