Sigma Gaming company, licence and legacy games

Sigma Gaming Limited is an active British software company with a current Gambling Commission remote gambling-software licence. Companies House records its incorporation on 17 September 2014, and the regulator shows the software licence active from 4 March 2015.

Game status: Birthday Bonanza is consistently attributed to Sigma Gaming by historical game catalogues, but no current first-party catalogue or live build was found during this check. Treat its card as a legacy record, not proof of current availability.

Company status, licence and Birthday Bonanza evidence checked 16 July 2026.

Sigma Gaming record in our directory

The title is shown with its existing SlotsLike thumbnail and links to its individual comparison page. The historical provider credit is useful, but exact mathematics and present distribution require current game evidence.

Birthday Bonanza

A party-themed legacy slot consistently credited to Sigma Gaming in historical catalogues. Release-era RTP, volatility, jackpot rules, stakes and format need confirmation from an actual build.

Company, licence and game availability are different checks

The Gambling Commission register establishes that Sigma Gaming Limited currently holds a remote gambling-software licence. It does not say which historical titles remain distributed, which operators carry them or whether an old Flash-era game has a supported HTML5 version.

Archived Sigma Games official company page from November 2023 — Sigma Games’ official company page as archived in November 2023. Regulatory status was checked separately in July 2026 because the live company domain presented a certificate problem.

The Sigma name also appears in unrelated contexts, including a historic Japanese gaming-machine business and the SiGMA events brand. Neither should be merged into the British company profile.

How to verify a Sigma Gaming title

Confirm the legal supplier

Look for Sigma Gaming Limited in the game’s legal or provider panel rather than relying only on the word Sigma.

Check the technology

Older catalogues can list Flash, JavaScript and HTML5 together. Confirm which build is actually available and supported today.

Read the live rules

Use the current help file for RTP, volatility, paylines, stake limits, maximum win and progressive-jackpot conditions.

Verify the operator

An active supplier licence does not prove that a particular licensed casino currently offers the game.

Sources and verification notes

Verification limit: official registers establish the current company and licence. Historical catalogues support the title credit but do not establish a current first-party catalogue, operator, build or configuration.
