The Play Magnus Story
Play Magnus launched in 2014 with a compelling concept: play chess against an AI modeled on Magnus Carlsen's play style at various ages, from 5-year-old Magnus through his peak adult years. The idea was brilliant — it gave the world champion a personal connection to every player, and the age-based difficulty made it intuitive.
The app was well-received and became part of the broader Play Magnus Group, which also included Chess24, Chessable, and other chess properties.
The Acquisition
In December 2022, Chess.com acquired the entire Play Magnus Group for $82.9 million. This brought Chess24, Chessable, and Play Magnus under the Chess.com umbrella.
What followed was mixed. Chess24 was explicitly shut down in January 2024. Chessable continues to operate and grow. Play Magnus, however, entered an ambiguous state — still technically available on app stores, but receiving minimal updates. The app hasn't been formally discontinued, but it's clearly not a priority for Chess.com's development resources.
Where It Stands Today
Play Magnus remains downloadable, but users report that the experience has degraded. Without active development, bugs go unfixed, and the app feels increasingly dated compared to modern chess platforms. For practical purposes, Play Magnus is a legacy product.
How Chessiverse Compares
The core idea behind Play Magnus — play against an AI opponent at a specific strength — is something Chessiverse does on a much larger scale.
One Opponent vs 1,000+
Play Magnus gives you one opponent (modeled on Magnus Carlsen) at different age-based difficulty levels. It's charming, but limited. Once you've played "Age 15 Magnus" a few times, the experience doesn't change.
Chessiverse offers 1,000+ unique bots, each with their own personality, play style, and opening preferences. At any given skill level, you have dozens of opponents to choose from — aggressive attackers, solid defenders, tactical players, positional grinders. The variety keeps practice fresh and helps you train against different types of opponents.
Age Levels vs Calibrated Ratings
Play Magnus's age-based difficulty is intuitive ("I can beat 10-year-old Magnus!") but imprecise. There's no direct mapping to standard Elo ratings, making it hard to use for structured improvement.
Chessiverse bots have ratings calibrated to match real human Elo ranges. A 1200-rated bot plays like a 1200-rated human. This precision matters for targeted practice — you know exactly where you stand and can incrementally increase the challenge.
Active vs Abandoned
This is the most important difference. Chessiverse is actively developed with regular updates, new features, and a growing content library. Play Magnus is effectively frozen in time. When you're investing practice time in a platform, active development means the experience keeps improving.
What Play Magnus Got Right
Credit where it's due: Play Magnus pioneered the idea of making AI chess personal and approachable. The concept of playing against a famous player at various life stages was creative and engaging. It proved that AI chess opponents could be more than just "Stockfish on level 3."
Chessiverse builds on this insight but takes it much further — instead of one famous player at different ages, you get an entire world of unique opponents, each with their own story and style.

Final Verdict
Play Magnus was a pioneer in making AI chess personal, but it's now effectively abandoned after Chess.com's acquisition. Chessiverse takes the same core concept — playing against AI opponents at your level — and expands it dramatically with 1,000+ unique bots, calibrated ratings, opening-specific practice, and active development. If you loved the idea behind Play Magnus, Chessiverse is where that idea lives on and thrives.
