Rush streak: 12Focus Score
Top 9%4.6/5
Sustained concentration across your last 20 sessions, measured by move-timing consistency.
"The board doesn't care how you feel. It only responds to what you calculate. Train the calculation, and the confidence follows on its own."
Daily Challenge
Mate in 3 — White to move
Why the daily challenge works
- Tuned to your rating. Difficulty adapts automatically so every puzzle sits right at the edge of your ability.
- One puzzle, real commitment. A single high-quality position beats fifty mindless ones — that's the whole design philosophy.
- Streaks that matter. Miss a day and your streak freezes for 24 hours before resetting — enough forgiveness to keep you honest, not enough to let you coast.
Real players, real boards
Training doesn't stop when you close the laptop.
Grandline Chess syncs your puzzles, ratings, and focus stats across every device — so the position you left mid-thought on your phone is exactly where you pick it back up, whether that's at your desk, in the park, or between rounds at a tournament.
- Cross-device sync. Start a puzzle rush on mobile, finish the review on desktop.
- Offline puzzle packs. Download a week of daily challenges before you travel.
- Built for the table, not just the screen. Log over-the-board games and get the same blunder analysis.
Inside the app
Six modes. One relentless climb.
Every feature in Grandline Chess is built around a single loop: play, get precise feedback, fix the leak, come back stronger.
Focus Training
Timed sessions that strip away distraction and score your concentration curve, not just your win rate. Learn exactly when your attention breaks down mid-game.
Puzzle Rush
Beat the clock across escalating tactical puzzles. Rush mode rewards pattern recognition speed — the same instinct that wins won games in real time trouble.
Interactive Lessons
Bite-sized courses from openings to endgame technique, narrated step-by-step with an AI coach that pauses and quizzes you the moment attention drifts.
Ranked Battles
Climb a seasonal ladder of nine divisions, from Pawn to Chaos Sovereign. Every match is fully rated, anti-cheat scanned, and archived for review.
Stats & Analytics
Every game broken down into accuracy, blunder rate, opening repertoire gaps, and time-management patterns — visualized so the fix is obvious, not just the flaw.
Community
Join clan-style crews, run weekly puzzle relays, and get your games reviewed by titled players in the Grandline Chess Discord and in-app clubs.

Today's mindset
Every blunder is just data you haven't reviewed yet.
Grandline Chess was built in 2021 by a small team of coaches and engineers in Lisbon who were tired of chess apps that made training feel like a chore. No fluff, no filler puzzles — just a system that gets you 200 rating points closer to who you're trying to become.
