Comprehensive Guide to Trannel International Limited Online Casinos (2025)

It is essential to note that all brands operated by Trannel International Limited are developed primarily for players outside the United Kingdom. These casino sites do not support English as a native language and do not accept UK registrations or GBP transactions. As such, we do not recommend attempts to access or play at these sites from the UK.

Otto Kasino

Otto Kasino stands out as the most recognizable brand among Trannel’s portfolio, mainly in Scandinavian markets. The site targets Finnish players and is characterized by a streamlined, minimalist design with a primary focus on online slots. Otto Kasino provides a rapid gaming environment, stripping away most extra features, promotions, or welcome offers. The user experience prioritizes game speed and simplicity over vibrant graphics or incentives. Due to its Finnish-only interface and geo-restrictions, UK-based players cannot access Otto Kasino. Even with browser translation, deposits from the UK are not accepted.

Kolikkopelit

The name ‘Kolikkopelit,’ meaning “slots” in Finnish, signals the site’s primary focus: an extensive collection of over 2,300 slot games from top developers. Kolikkopelit also features bingo, live casino tables, exclusive titles, and even offers live-streamed cultural content from Finnish museums, later available via its YouTube channel. Notably, the “Sauna Game” is a unique highlight under its Finnish-themed games section. While Kolikkopelit offers a more diverse experience than Otto Kasino, it remains unavailable and unsupported for UK users.

CasinoHuone

CasinoHuone, translating to “casino room,” is treated as Trannel’s flagship property. This brand attracts significant promotional activity, unlike Otto Kasino and Kolikkopelit. CasinoHuone boasts regular free spins, deposit match offers, “happy hour” deals, and periodic prize draws such as gift cards. While the site’s catalogue includes a variety of slots and bingo, its standout feature is a robust online poker section, complete with learning resources suitable for beginners. The user interface and promotions emphasize a community atmosphere for poker enthusiasts. CasinoHuone, like Trannel’s other brands, does not grant access to UK-based audiences.

Storspiller

‘Storspiller’ translates from Norwegian as “big player,” and the site is designed for high rollers and table game aficionados. The casino’s logo, featuring dice, hints at its table and card focus, but it also provides a suite of progressive jackpot slots, including exclusive versions of famed titles such as “Mega Moolah.” Regular tournaments and an active poker section cater to experienced players. The site is offered in Norwegian and targets Scandinavia and parts of continental Europe; restrictions prevent access from the UK.

Trannel International: Corporate Overview

Many UK online casino players may recognize the Trannel International Limited name primarily through its indirect connection to Unibet. Officially, Unibet’s UK operations fall under Platinum Gaming Limited, but the corporate structure ties both entities together under a common ownership through the Kindred Group plc, a major international gambling conglomerate.

Founded as Plus One Dreams Limited in 2000 before adopting the Trannel identity, the company employs around 1,600 people and has reported annual revenues surpassing £600 million, reflecting activity from Trannel and associated brands. However, this figure likely amalgamates revenue streams from various sources within the Kindred Group, not just the four main Trannel casinos. Current player numbers across the network exceed one million monthly actives, although distinguishing individual brand contribution is complex due to the structure of the Kindred ecosystem.

Unibet, launched in 1997 prior to Trannel’s formation, became the dominant identity within the group. Over time, Trannel’s operations receded behind the parentage of the Kindred Group, which today manages a diversified portfolio of gaming brands worldwide.

The Kindred Group: Parent Company Background

The Kindred Group is a global powerhouse in the online gambling industry, with offices in Malta, the UK, Gibraltar, Sweden, Italy, France, Australia, and the USA. The company prioritizes innovation, customer trust, and social responsibility, striving to implement sustainable business practices aligned with global standards—such as their 2020 revision to emissions targets as part of the Paris Agreement. Growth in recent years has seen Kindred acquire brands such as Belgian Biancas Casino and expand Unibet’s reach into several US states taking advantage of changes in American sports betting laws.

Apart from Trannel’s brands and Unibet, Kindred’s portfolio includes prominent names like 32Red, Maria Casino, Vlad Cazino, and Bingo.com, catering to a wide array of gaming preferences. The group’s emphasis on safe, innovative, and responsible gaming underlines its mission and industry influence.
