Lotus Chess

Lotus Chess is a gamified chess training app developed in Germany by Raphael and Maxim Nitsche, the children of renowned chess programmer Thomas Nitsche. It takes a systematic approach to improvement: instead of dropping you into an ocean of positions and hoping something sticks, Lotus Chess builds structure around the parts of the game that matter most, starting with openings.

At the core is LotusAI, which analyzes all major openings and identifies the most advantageous and human-practical lines. Rather than feeding you endless theory, it builds you a bulletproof repertoire and then tracks your actual win rate for each opening line based on your game history. If a particular line is losing you games, the app surfaces it. You can see exactly where your opening knowledge breaks down and drill that specific gap.

The training system extends beyond openings. Lotus Chess includes over 100,000 tactics puzzles with difficulty tuned to your level, endgame training, and personalized courses. The app uses gamification to keep sessions engaging: streaks, progress milestones, and level-up feedback replace the dry grind of traditional chess study.

A key differentiator is full offline support, so your training continues on a plane, commute, or anywhere without a reliable connection. The app is available on iOS and Android, was launched in late 2024, and reached its latest version 2.5.1 in March 2026. With a growing community of learners and chess DNA baked in from the start, Lotus Chess is one of the more thoughtfully designed training apps in the space.
