Biter of Seville
release date and demo

Biter of Seville is a newly announced slot from Happy Duck, a London-based studio founded in 2025 that released its first titles earlier in 2026. The game is confirmed for 21 August 2026, one of several Happy Duck releases scheduled across the second half of this year.

Happy Duck has not published any of this game's specs. RTP, volatility, max win, mechanic, theme, features, grid, paylines and stake range are all unconfirmed. The studio has simply not released those details yet. Until they arrive, this page is grounded in what is verifiable: the studio's identity, its developing catalogue record, and the confirmed release date.

The name Biter of Seville is the only creative signal the studio has put out so far. It gives you something to consider, but it tells you nothing definitive about how the game plays, what it looks like or what its features are. Those details will follow from Happy Duck on or around 21 August.

Biter of Seville releases 21 August 2026, one of several confirmed Happy Duck titles arriving in the second half of this year.

Happy Duck is a very new studio, which means its catalogue record is still forming. Here is what is on record across its games to date:

• Catalogue size: approximately 18 games, with 7 carrying a confirmed release date as of mid-2026.
• Published RTPs: too few of the studio's titles carry a published RTP to produce a meaningful catalogue figure. This is common for a studio this early in its run.
• Volatility on record: not enough of the studio's titles have been rated to describe a volatility lean or identify a pattern.
• Mechanic patterns: Happy Duck has not been active long enough to have a signature mechanic on record across its catalogue.
• Theme range: confirmed titles include Kraken Deals, Storm Talisman, Al the Chemist, Sushi Slice and Zeus Maxxing, which points to a varied spread of concepts rather than a single focus.

None of this applies directly to Biter of Seville. The studio has not confirmed that this game follows whatever patterns do emerge from its other releases, and there is no basis to assume it will. The real specs will come from Happy Duck on or after 21 August.

Happy Duck's 2026 release pace is worth noting. Sushi Slice is due on 14 August, just ahead of Biter of Seville, and Zeus Maxxing follows on 28 August, with Al the Chemist announced for 4 September. Whether consistency holds across that cadence is something the desk will track as each game lands.

The free demo for Biter of Seville is not live yet. It goes live on 21 August 2026, alongside the full game, and is the straightforward no-risk way to try it before committing real money.

We will embed the demo directly on this page once it is live on launch day, so you can try it here without having to search elsewhere. No deposit is required to play a demo.

For real-money play, Biter of Seville will be available at casinos carrying Happy Duck titles from the release date. We will list confirmed casino availability here once operators have gone live with the game. If you already play at a casino you know carries Happy Duck slots, that is the practical first place to check on 21 August.

Once Biter of Seville is out and Happy Duck has published its specs, this page will be updated with:

• The studio's published specs for this game: RTP, volatility rating, max win, confirmed mechanic, features, grid layout and stake range.
• The playable free demo, embedded here from 21 August 2026.
• Our tested review after a real-money session at the desk, with an honest account of how the game plays in practice.

The specs come from the studio and the review comes from actual play. We do not publish either until they are real. Both will be added as soon as they are available after launch.
