Best Online Casinos 2026

Since 1996

NetEnt is one of the oldest and most respected slot studios in the industry, founded in Stockholm in 1996. It was among the first developers to move casino games from land-based machines to the web, and its HTML5 engine now powers titles across hundreds of licensed online casinos.

Since 1994

Microgaming is widely credited with launching the first true online casino software back in 1994, making it the oldest developer still active in the industry. Based on the Isle of Man, it now operates as a content aggregator, distributing games from its own studio alongside dozens of independent partner studios.

Since 2006

Evolution is the dominant name in live dealer gaming, operating broadcast studios on multiple continents that stream professionally hosted roulette, blackjack, baccarat and poker around the clock. Founded in Stockholm in 2006, it merged with fellow provider NetEnt in 2020 to become one of the largest listed gaming groups in the world.

Since 2015

Pragmatic Play launched in 2015 and grew rapidly into one of the most prolific slot studios in the industry, releasing new titles on an almost weekly schedule. It has since expanded into live casino, bingo and a sportsbook product, but slots remain its core business.

Since 1997

Play'n GO was founded in Sweden in 1997 and was one of the first studios to build its entire catalogue mobile-first, well ahead of most of the industry. It is privately held and headquartered in Malta.

Since 1999

Playtech is one of the largest publicly listed gaming technology companies in the world, founded in 1999. Beyond slots, it supplies full platform infrastructure, live casino studios and sports betting systems to operators globally.

Since 2014

Red Tiger was founded in 2014 and quickly built a reputation for fast-paced, high-volatility slots and jackpot networks. The studio was acquired by NetEnt in 2019 and now operates as part of the Evolution group.

Since 1975

International Game Technology traces its roots to 1975 and is one of the largest gaming equipment and software companies in the world, with a long history supplying physical slot machines to land-based casinos before moving into online gaming.

Since 2006

Betsoft launched in 2006 with a focus on cinematic, 3D-animated slots at a time when most competitors were still using flat 2D graphics — its ToGo mobile-optimised range helped set an early standard for visual quality on smaller screens.

Since 2013

Yggdrasil was founded in 2013 by former NetEnt developers and set out to build a boutique studio focused on technical polish and reusable bonus mechanics shared across its slot range, such as its 'Splitz' and multiplier-stacking features.

Since 2018

Spribe was founded in 2018 and is widely credited with popularising the crash-game genre through Aviator, a simple multiplier game where players cash out before a plane 'flies away' — a format that has since been copied across the industry.

Since 2017

Stake Originals is the in-house game studio built alongside Stake.com when it launched in 2017. Rather than licensing third-party slots for its core lineup, Stake built its own catalogue of provably fair instant games designed around transparent, verifiable outcomes.
