Indie studio Stray Fawn and Sidekick Publishing have announced a global co-publishing partnership for Gambonanza, a turn-based roguelike chess-builder. The game is developed by solo creator Paul Giovannini of Blukulélé Studio, who aims to reimagine classic chess on a smaller, high-risk board designed to emphasize strategy and decision-making.
The project has already attracted attention since its trailer debut in March 2025, which has accumulated over 560,000 views. A public Steam playtest is now available, offering early access for players to try the game and provide feedback ahead of a planned PC and mobile release later in 2026.
Mobile Ports and Development Partners
Digital agency Ateo has joined the project to oversee mobile ports of Gambonanza, expanding its availability beyond PC. The collaboration brings together a European indie “dream team,” with Stray Fawn, Sidekick Publishing, and Ateo all having a history of previous projects. Stray Fawn and Sidekick Publishing previously worked together on TerraScape, while Ateo has collaborated with both studios on other mobile releases.
According to Stray Fawn co-founder Philomena Schwab, the partnership formed quickly after the team discovered Giovannini’s trailer online. “Within hours, I reached out to Paul to ask about a possible collaboration,” Schwab said. “When he said yes, it escalated into a small party at the office. Now, with Ateo and Sidekick joining, we have another milestone to celebrate.”
Gameplay and Strategic Design
Gambonanza turns traditional chess mechanics into a roguelike experience, played on a condensed board that encourages high-stakes decision-making. Each match requires players to balance risk and reward, with unique gameplay elements that differentiate it from standard chess titles. The public Steam playtest allows players to explore these mechanics, share feedback with the developers, and experience early content ahead of the game’s wider release.
Sidekick Publishing co-CEO Jasmin Oestreicher described the project as an opportunity to bring a classic board game to modern platforms with a new twist. “This partnership allows us to reunite with our long-term friends at Stray Fawn and Ateo, building on that foundation of trust,” Oestreicher said. “We are committed to Paul’s vision for Gambonanza and look forward to applying our collective expertise to make it a global success.”
Public Playtest and Upcoming Release
The Steam playtest is live now, offering a first look at the game’s roguelike chess mechanics. Players can experiment with strategies, test different builds, and contribute feedback that will inform future updates. The team has confirmed that a free demo and full release for PC and mobile are scheduled for later in 2026, with plans to highlight the game during Steam Next Fest.
