Cozy Sudoku

Cozy Sudoku launched on September 17, 2024 as a complete puzzle game featuring thousands of pre-built Sudoku puzzles, customizable themes, background music, and interactive cats. The store description presents it as a fully-featured package with no mention of future content, expansions, or a content roadmap. Since launch, the developer has been actively maintaining the game through a series of patches: early post-launch updates added keyboard controls and fixed bugs, a November 2024 update (v1.3.0) added new cat characters and UI improvements, and a December 2024 cluster of updates (v1.4.0–1.4.3) added a new "Stamp Fill" gameplay mode, optimized performance, extended Linux/SteamOS compatibility, and applied security fixes. The most recent developer communication was on December 26, 2024. All post-launch updates have been improvements and quality-of-life additions to the existing game rather than expansions of new puzzle content or named DLC. There are no unreleased DLC entries on the store, no announced roadmap, and no developer statements indicating additional major content is planned. The game appears to have launched as a complete product and has been polished through ongoing maintenance. Given that the developer has been silent since December 26, 2024 — over six months as of today — and no future content has been signaled, the game is best understood as a finished, content-complete product.
