Developer Overview

Founded in 2007 in Ukraine, Only Play has grown from humble beginnings into a globally recognised brand with an impressive portfolio of games and a strong international presence.

The company has always been quick to embrace new technology, particularly in the mobile gaming space. Recognising the potential early on, Onlyplay adopted a mobile-first approach to slot development, positioning itself as a leader in the industry.

The designs and features are often cited as unique, and this vendor rightly calls itself an ‘innovative trendsetter’.

Onlyplay’s Top 5 Games

Trying out a new developer’s products at online casinos is worth starting with the most popular Onlyplay slots. The Slotozilla experts have found the following to be the most well-liked options for British users.

1. Book of Bamboo

• Theme: Animal/Adventure
• 5×3 with high volatility and free spin bonuses
• Bet Range: 1.00 to 50.00
• RTP: 96.22%
• Max Win: 5,000x

We noticed that Book of Bamboo was a big hit as we examined numerous platforms and their gaming content while creating casino sites reviews. It transports the player to the forests of Japan, where they enjoy a traditional grid slot with a very respectable 96.22% return to player rate. Note that this percentage can vary depending on which Onlyplay casinos you use. The minimum bet is a little rich, but the high volatility makes for thrilling gameplay.

2. Troll Dice

• Theme: Fairy Tale
• 3×3 game with instant win mechanics
• Bet Range: 0.01 to 100.00
• RTP: 93%
• Max Win: 118x

Troll Dice is a left-field offering from Onlyplay that has become a mainstream success. It offers a unique take on the fairy tale world. The return-to-player rate isn’t high, but that’s because of the instant win mechanics, which are guaranteed to keep users on the edge of their seats. According to our experts, Troll Dice is genuinely one of the most unpredictable titles they’ve played.

3. Juicy Crush

• Theme: Fruit
• 6×6 slot with cascading mechanics
• Bet Range: 0.20 to 50.00
• RTP: 95.35%
• Max Win: 5,000x

A vibrant game that makes good use of the classic theme, Juicy Crush makes use of a larger-than-average 6×6 grid format. The return to player rate is strong, the max win is excellent, and the cascading mechanics keep the grid constantly moving. Players who appreciate a new approach to a traditional theme will enjoy this activity.

4. Royal Kitties

• Theme: Animals
• 5×4 grid slot with medium volatility and expanding wilds
• Bet Range: 0.20 to 100.00
• RTP: 95.34%
• Max Win: 1,000x

Cats rule the world in this highly unusual yet charming little slot game. The medium volatility and decent return-to-player rate keep the wins coming, and the expanding wilds introduce an element of chaos. This is a very balanced title, so those who like a steady stream of medium-sized wins should definitely take note.

5. Crystal Cascade

• Theme: Aliens/Crystals
• A large 8×8 grid slot with cluster pays
• Bet Range: 1.00 to 50.00
• RTP: 95.45%
• Max Win: 10,880x

As Onlyplay games go, this one has a bit of everything. There’s the high volatility, the competitive return to player rate, and the fact that the grid is so large. The 8×8 format can look a little daunting to newer players, but the same principles apply, and the cluster pays mechanic keeps symbols coming and going. This bright and exciting space-themed adventure demonstrates the creativity behind Onlyplay games.

Onlyplay Slots: Ins and Outs

No developer of slots is perfect across the board, but those who play Onlyplay slots online know that this one is good at playing to its strengths. Here are the pros and cons of playing their games at online casinos.

• Varied volatility for different player preferences

• Unique and creative themes

• Stunning graphics with vibrant colours

• Many bonus features, from free spins to multipliers, cluster pays, cascades and more

• Not all Onlyplay games have high RTPs

• Not available worldwide, as the company is still building its distribution network

Why You Should Try Onlyplay Slots Online

Unsure whether Onlyplay slots are the right option for you? If you’re a fan of quirky and adventurous themes, as well as innovative in-game mechanics and formats (such as larger grids), then they could be the perfect choice. If, on the other hand, you’re looking for something a bit darker in theme, perhaps not. According to our experience, the fact that these titles have varied volatility levels makes them popular with players, which is worth considering.
