Who is 4ThePlayer?
4ThePlayer is an independent game studio founded in 2018 by industry veterans Andrew Porter and Chris Ash. The London-based provider has quickly become one of the most talked-about challenger brands in iGaming. What sets them apart is their focus on innovation, concise gameplay, and mobile-first design. They are not flooding the market with copy-paste slot games. Instead, they are crafting unique games with fresh mechanics and smart maths.
The first release, 9k Yeti, launched in 2019 and immediately gained traction with its 97% RTP and high volatility. It introduced the studio’s signature BIG REEL PORTRAIT™ mode—essentially a vertical layout optimised for smartphone screens. Since then, 4ThePlayer has launched dozens of inventive titles like 2 Gods: Zeus vs Thor, 90k Yeti Gigablox, and 60 Second Heist. They have also dabbled in crypto-friendly table games like 100 Bit Dice and 1000x Busta.
They hold a UK Gambling Commission licence, plus additional approvals in Sweden, Romania, and across the United States. The team has won awards for innovation and continues to grow, now offering over 40 games in more than 30 languages. Playing on 4ThePlayer casinos is therefore a legitimate and secure experience.
Popular 4ThePlayer Slot Games
4ThePlayer might not have the largest library, but nearly every release offers something different. Their slots are high volatility, mobile-optimised, and built with the player experience front and centre. Below are some of their top games, which you will find in the majority of the 4ThePlayer online casinos in the UK:
9k Yeti
- RTP: 97%
- Max Win: 9,012x
- Volatility: High
- Special Feature: Snowstorm Bonus Reshuffle
The debut release and a cult hit. Clean visuals, high max win, and the game that introduced BIG REEL PORTRAIT™ mode.
90k Yeti Gigablox
- RTP: 95.5%
- Max Win: 90,000x
- Volatility: Extreme
- Mechanic: Yggdrasil’s Gigablox
A sequel on steroids. Gigablox symbols go up to 6x6 in size. Watch out for the Snowstorm and Giga Summon modifiers during free spins. This is one of my favourite 4ThePlayer slots.
4 Fantastic Fish
- RTP: 96%
- Max Win: 15,000x
- Volatility: High
- Feature: Cash Ways mechanic
A 4,096-way slot that brings jackpots, respins, and money symbols. Look out for sharks that collect wins and giant squids that reshuffle the reels.
60 Second Heist
- RTP: 96%
- Max Win: 60,000x
- Volatility: High
- Gimmick: Time-based free spins
This slot flips the script. Instead of counting spins, your bonus is timed. Race against the clock for multiplier wins and retriggers. Quite an innovative, even among the 4ThePlayer games.
4ThePlayer Casino Bonuses
While 4ThePlayer games do not come with dedicated casino bonuses, many top UK casinos that host their games offer general promotions that can be used on them. These include:
- Matched deposit offers
- Free spins
- Cashback
- Reload bonuses
You may find free spins applied to popular 4ThePlayer slots such as 9K Yeti or 4 Fantastic Fish. Just ensure the bonus terms allow play on these games and always check the wagering requirements before opting in.
4ThePlayer Gambling Licenses and Secure Gameplay
4ThePlayer is licensed by the UK Gambling Commission (UKGC)—widely regarded as one of the strictest regulators in the world. They also hold gaming licences in Sweden, Michigan, and a transactional waiver in New Jersey, among others.
All games are built using HTML5 for full compatibility across devices. Game fairness is guaranteed by independent testing agencies. The studio also employs SSL encryption, responsible gambling tools, and avoids any childlike imagery in its games. Their focus is adult entertainment in a secure, regulated environment.
