Odd||Even

Odd||Even launched on April 6, 2016 as a self-contained math and logic puzzle game featuring 90 curated puzzles, a puzzle generator, and a set of clearly defined features. The store description reads as a finished product — it lists a specific puzzle count, touts full commercial rights upon purchase, and makes no mention of planned updates, future content, or ongoing development. The developer has never posted a content update, patch note, roadmap, or any development communication beyond two trading card-related posts. With nearly a decade since release and no post-launch content activity of any kind, this game launched as a complete, finished product and has remained so.
