Evaluation
Pure Logic is a self-contained puzzle game that launched on April 24, 2023 with over 200 puzzles. The developer shipped one meaningful post-launch update — "The Big Flexibility Update" on June 29, 2023 — which added unlimited undo and expanded solving flexibility in response to player feedback. Subsequent updates (November 2024 and February 2025) were quality-of-life and UI refinements rather than new content additions.
The developer's attention has since shifted to a second game, Mirrors of Epiphany, which launched in mid-July 2025. The most recent news post (July 21, 2025) announces a bundle between the two games but contains no mention of any planned content for Pure Logic itself. There are no unreleased DLC listings, no announced roadmap, and no developer statements promising additional puzzles or features. The store description describes the game as a finished 200+ puzzle experience.
This is a complete, finished puzzle game. Someone waiting for all content can play it now.
Evidence
The Big Flexibility Update added unlimited undo and direct signal toggling — the only substantive post-launch content update.

About this game
Pure Logic is a puzzle game based on logic in its raw and pure form. Use your deductive reasoning skills to conquer more than 200 unique puzzles.
Gameplay
Each puzzle consists of an array of interconnected logic gate symbols. Some of the input/output signals are initially set, some are not. The challenge is to figure out and set the remaining signals so that all symbols are satisfied.Explore and discover
No prior knowledge of logic gates is required to start playing. The in-game training grounds let you explore the different symbols, and you'll quickly discover and learn the basic rules.Relaxing
There are no time limits. You can enjoy solving all the puzzles at your own pace.Solving flexibility
Pure Logic was initially released with a last-step-only undo mechanism. Due to popular demand "The Big Flexibility Update" was released in June 2023, adding support for unlimited undo. The update also added the possibility to change any set signal directly to the other colour/state, or reset it back to its original unset state. This opens up for a wide range of solving strategies.Educational value
The gameplay is based on real-world logic gate symbols and the Boolean functions they represent. Logic gates are the basic building blocks of digital electronics and computer hardware. Boolean functions play a crucial role in all levels of computer programming.Are these done yet?
