Big Time Gaming Megaways: how BTG rewired online slot design

By Nina Brooks, Casino Correspondent

Big Time Gaming (BTG) was founded in 2011 and is best known for inventing the Megaways™ mechanic with the 2016 release of Bonanza; that mechanic varies symbol heights each spin to create as many as 117,649 potential win ways and has since been licensed to hundreds of developers worldwide. The studio built a catalogue of high-volatility titles — including Bonanza, Extra Chilli, Lil Devil and Danger! High Voltage — and has continued to expand its family of mechanics with systems such as Megapays™, Megapots™, Megaclusters™, Megadozer™ and Megaquads™.

Big Time Gaming’s origin and core approach

Big Time Gaming launched in 2011 with a development philosophy centred on rethinking slot mechanics rather than following established templates. The studio’s stated aim is to challenge conventions and introduce technical systems that change how players experience video slots. That focus on mechanics and mathematical design underpins both its original titles and its later licensed products.

BTG established a reputation for high-volatility gameplay early in its catalogue. Titles named by the studio as signature releases include Bonanza, Extra Chilli, Lil Devil and Danger! High Voltage. The studio also worked on branded conversions, producing slots that carry established entertainment IP such as Who Wants To Be A Millionaire™, Wheel of Fortune™ and Monopoly™.

How Megaways changed slots — big time gaming megaways

Megaways™ arrived inside Bonanza in 2016 and replaced fixed paylines with a dynamic reel structure where each reel can display between two and seven symbols on any given spin. This variability produces a wide range of possible symbol alignments; at peak configuration a single spin can present up to 117,649 distinct win ways. The mechanic removed the static expectations of paylines and created a gameplay layer built around changing combinatorics rather than fixed lines.

Operators and suppliers rapidly adopted Megaways™; the mechanic is licensed to hundreds of third-party developers, which made it one of the most widely used proprietary systems in online slot development. That licensing model allowed the mechanic to scale into a broad set of themes and volatility profiles while keeping the underlying engine common across many studios.

Extending the concept: Megapays, Megaclusters and other BTG systems

BTG did not stop at Megaways™. The studio introduced a range of derivative and complementary mechanics designed to offer different kinds of variability and reward structures:

• Megapays™ and Megapots™: systems aimed at introducing progressive-style jackpots and pooled prize mechanics within BTG’s variable-reel architecture.

• Megaclusters™ and Megaquads™: concepts that change grid geometry, allowing clusters of symbols or multiple merged grids to alter how winning combinations form.

• Megadozer™: a further evolution that adjusts how symbols and layouts shift across spins to create evolving play states.

Each new mechanic builds on the premise that slot geometry and symbol distribution are design levers as important as theme, volatility and RTP. These systems give operators a range of product behaviours to deploy across player segments.

Product portfolio and branded collaborations

BTG’s catalogue mixes purely original titles and branded adaptations. Core original hits cited by the studio include Bonanza and Extra Chilli; the company also lists Lil Devil and Danger! High Voltage among its influential releases. On the branded side, BTG has produced slot conversions of global entertainment properties including Who Wants To Be A Millionaire™, Wheel of Fortune™ and Monopoly™.

Branded games required marrying the BTG mechanics to recognisable IP elements — a process that produced both high-variance originals and more familiar, branded user journeys. That dual approach helped the mechanic reach casual players via known brands and more experienced players via novel mathematics.

Compliance, footprint and corporate context

Evolution AB presents Big Time Gaming within its brands portfolio. Evolution notes its group licensing footprint: Evolution Malta Holdings Limited is licensed and regulated in Great Britain by the Gambling Commission under account number 41655, while Evolution Gaming Malta Limited holds a licence from the Malta Gaming Authority under licence MGA/CRP/187/2010/01. Evolution states it holds additional licences across multiple jurisdictions; a full list of licences is available from the company.

The group frames ownership of BTG as part of a broader studio and IP strategy that combines in-house mechanics development with licensing arrangements that allow third-party studios to use BTG technology.

What operators and platform vendors should note

Operators evaluating BTG content or Megaways-derivative mechanics should treat the offering as a mechanics-led product play rather than a theme-first release strategy. The primary commercial ingredients are:

1. A mechanics hook that alters payline expectations and can raise average spin volatility.

2. Licensing terms that permit broad third-party adoption, which affects supply and differentiation.

3. Portfolio balance between original high-volatility hits and brand-led games that reach wider audiences.

For platform vendors and aggregation services, the widespread licensing of Megaways™ means demand for integration and metadata that correctly represent variable-reel behaviour. Game-presentation layers need to display changing reel heights, varying win ways, and the specific jackpot or cluster behaviours required by Megapays™, Megapots™ and Megaclusters™.

Where this sits in the market

Big Time Gaming’s influence is primarily technical: the studio introduced a set of mechanics that changed how designers think about reel architecture. Megaways™ became an industry standard through licensing, and BTG’s subsequent mechanics—Megapays™, Megapots™, Megaclusters™, Megadozer™ and Megaquads™—extend that technical footprint into progressive features and alternate grid forms. Evolution presents these brands inside its portfolio while holding licences in the UK and Malta.

Operators, platform vendors and regulators will continue to encounter BTG mechanics across product roadmaps and managed portfolios. For operators the commercial questions are familiar: how to balance conversion and retention when deploying higher-volatility mechanics, and how to present regulatory-required information about volatility and RTP to players.
