Arithmetic

Arithmetic launched on February 17, 2025 as a free-to-play puzzle game with 75 levels, 15+ operators, and a custom level editor. In the weeks following launch, the developer shipped several patches addressing bugs and quality-of-life improvements, including an undo feature and level editor overhaul. On August 9, 2025, the developer shipped the game's only major content update, adding an Endless Mode with randomly generated stages and a new Challenge Mode variant. This represents the last developer communication on record. There have been no posts, announcements, or updates since August 9, 2025 — over 10 months of silence. The store description presents the game as a self-contained package with a fixed level count (75 levels) and no announced future content. No DLC has been listed, no roadmap has been published, and the developer has not indicated further updates are planned. The game reads as a complete, finished product that received one round of post-launch polish and a mode expansion before going quiet.
