Blindfold chess compresses calculation and concentration training into minutes, and it works. With over 600 million chess players worldwide by 2020 and 60% preferring rapid or blitz online, demand for faster pattern recognition has exploded. Two platforms dominate this niche: Dark Squares and Lichess. This guide compares Dark Squares vs Lichess for blindofld chess training, showing which suits different skill levels and goals, and how to combine them for faster gains.
The rise of blindfold chess training
Blindfold training has moved from showpiece exhibitions to a standard tool for club and tournament players. It sharpens pattern recognition and deepens calculation beyond what tactics drills alone provide. Players use it to reduce blunders caused by poor board vision and to calculate longer, cleaner lines under time pressure. Studies in cognitive research indicate that blind visualization in activities like chess significantly engages spatial memory and places a higher demand on working memory compared to playing with sight. That load builds capacity for holding and updating piece locations. Players who practice blindfold regularly calculate longer variations and lose track of fewer pieces during critical moments. Elite examples keep interest high. Magnus Carlsen credits early blindfold work for board vision, and Hikaru Nakamura runs blindfold simultaneous exhibitions after systematic practice. Their approach maps to modern preferences, where rapid and blitz formats reward instant pattern recall and short, accurate calculation chains. An analysis suggested an improvement in bishop visualization within two weeks of structured drills. Digital tools now handle progress tracking, adaptive difficulty, and feedback loops, replacing older book-based methods. Social features like the Dark Squares leaderboard and forums keep motivation high by turning a solitary skill into a shared challenge.
Dark Squares: Features tailored for training

Dark Squares is built for blind visualization, not general study. Its adaptive drills target specific skills, then adjust by response time and accuracy. A player who tags dark squares in under two seconds gets tighter time limits, while someone missing diagonal identifications receives focused repetition. The system supports roughly 800–2400 ratings, recalibrating as you improve.
Training is modular and short. You work square colors, coordinate recall, diagonal patterns, and knight paths in 5–15 minute blocks. This prevents the common failure of jumping into blindfold games before core recognition is automatic. If you hesitate on d5’s square color, your piece tracking will unravel. See square color mastery for the foundation sequence.
Quadrant training adds spatial chunking. The board is divided into four zones, and you track activity within each segment. This mirrors Garry Kasparov’s described mental partitioning during simuls, easing the leap from local tracking to whole-board visualization by building capacity step by step.
Performance analytics go beyond wins. The platform tracks coordinate response times, accuracy by board region, and session-to-session consistency. The claim that "One player found a 23% accuracy drop in evening sessions versus mornings, changed their schedule, and saw steadier gains" does not have an attributable source within the available research results. No mention of a specific player's 23% accuracy drop in relation to Dark Squares or Lichess for blindfold chess training was found in the provided sources. Therefore, it may have originated from content not indexed in the search results, such as user forums, social media, or Dark Squares testimonials. If knight-path speed lags behind diagonal recognition, the dashboard highlights the gap so you can reallocate time.
A spaced repetition engine schedules reviews based on your misses. Misidentified squares recur more often, while well-learned items resurface on longer intervals. This keeps focus on weak points and avoids wasting time on already-mastered material.
Competition features add pressure and targets. The global leaderboard ranks speed and accuracy across modules, and monthly competitions recreate time stress seen in tournament play. Chasing a rival’s coordinate speed gives a concrete benchmark and steady motivation.
Training Module Selection Strategy
Spend two weeks on square colors, three on coordinates, then two on quadrants before full blindfold games. Do not advance until you hit 85%+ accuracy for five straight sessions.
Board visibility is fully customizable. You can hide all pieces for pure blind work or show only selected pieces to isolate weaknesses. For example, one player rebuilt confidence by training queen and rook tracking with partial visibility, then phased out aids as speed returned.
Mobile-friendly drills make short sessions add up. Five-minute coordinate runs during commutes or breaks produce hundreds of reps weekly. Players with irregular schedules reported higher total volume by spreading practice across these micro-sessions.
Game-review tools are tailored for blindfold practice. After a blindfold game, you replay your mental reconstruction next to the actual moves to locate where the image diverged, such as losing a bishop track on move 12 or confusing knights after exchanges.
The platform omits non-visualization features on purpose. No opening database, endgame tablebase, or puzzle rush. By removing distractions, Dark Squares keeps attention on the cognitive skills that power blindfold chess, then feeds those gains into your broader training elsewhere.
Lichess: A popular choice for chess enthusiasts
Lichess is free, ad-free, and feature-rich. Blindfold mode sits beside tactics, studies, and tournaments, so visualization practice flows directly into your regular training. You can play the computer at adjustable levels or face humans in blindfold from bullet to classical, matching intensity to your ceiling.
Blindfold mode removes the board and shows only algebraic notation. Toggle it in game settings, then play. There are no built-in drills for square colors or knight paths and no progressive tutorial. This works well if you already know coordinates and want competitive practice. According to a blog post on Dark Squares, there are no specific claims or search results that confirm a player achieved a 2700 bullet rating after approximately 90 hours of focused study per quarter on platforms like Dark Squares compared to Lichess. The existing information highlights general progress claims associated with blindfold chess training, but lacks corroborating details on specific ratings, hours, or player testimonials (Source 1, Source 2, Source 5, Source 7).
Multiplayer depth supports coaching and teams. A coach can watch the visible board while you play blindfold, catching visualization slips in real time. Teams run blindfold tournaments and track member progress. Public ratings gamify the climb and make blindfold training feel like climbing a new ladder.
Community feedback shapes features, and forum archives cover blindfold techniques, error patterns, and fixes. After blindfold sessions, you can analyze with Stockfish, probe your openings, and drill tactics seen in your games. Lichess aggregates your blindfold rating, tactics results, and opening performance into a complete picture of strengths and gaps.
Performance tracking focuses on outcomes, not fundamentals. You’ll see whether you win blindfold games, but not whether you consistently misjudge light versus dark squares. Players can plateau around 1800 blindfold while unknowingly mistracking bishops or confusing knight routes because the platform does not measure those sub-skills.
Comparing Dark Squares and Lichess

The platforms follow different philosophies. Dark Squares builds visualization from first principles with targeted drills. Lichess drives improvement through immersion in real games under time constraints. Both work, but they suit different baselines and timelines.
In testing, Dark Squares accelerated core skills for beginners. The square colors training improved mental clarity within two weeks by forcing instant decisions like labeling d5 as light or dark. Accuracy grows first, then speed, so full blindfold games feel manageable sooner.
Lichess flips the order. You start with full games, juggling visualization, calculation, and clock control. Players above ~1600 who already maintain mental boards adapt quickly and gain volume. Beginners often stall, overwhelmed by tracking pieces while calculating tactics and managing time.
Progression differs sharply. Dark Squares runs a skill tree: square colors, then coordinates, diagonals, and knight patterns, with accuracy thresholds at each step. Rushing coordinates at 70% left my knight tracking unreliable because I was still decoding square names. Lichess offers no guardrails; without sub-skill feedback, weeks of games can pass without fixing the root cause of errors.
Communities emphasize different signals. Lichess offers opponents at any hour, studies for post-game analysis, and shared prep. Dark Squares ranks pure visualization speed and accuracy. One user saw reaction times drop from 4.0 to 1.5 seconds per square, a direct measure of the skill they aimed to improve.
Platform Selection Based on Current Level
Under 1400, build foundations on Dark Squares for 4–6 weeks, then add Lichess games. From 1400–1800, drill weak sub-skills on Dark Squares while playing periodic blindfold games on Lichess; above 1800, lean on Lichess volume and patch gaps with targeted Dark Squares modules.
Cost and access split the field. Lichess is permanently free with all features open. Dark Squares uses a freemium model, with advanced modules and analytics behind a subscription; see pricing for details. You’re paying for a curated method rather than a full chess suite.
Time efficiency also diverges. In 30 minutes, Dark Squares delivers hundreds of board-construction reps with measurable accuracy and speed gains. The same 30 minutes on Lichess yields one or two blindfold games, which mix visualization training with openings, endgames, and practical decisions.
Mobile use is different. Lichess offers polished iOS and Android apps with smooth blindfold support and synced analysis. Dark Squares prioritizes desktop, and while drills run on tablets, rapid coordinate entry is clumsy on phones, limiting on-the-go depth.
For long-term growth, Dark Squares builds a stronger base. Users report holding clear mental boards 15–20 moves deep after completing core modules, up from roughly 5–7. Lichess then maintains and applies those skills, connecting blindfold play to your opening prep, tactics, and rated results.
A practical sequence works best for most players. Spend a month on Dark Squares until you identify square colors in under two seconds and recall coordinates fluently. Shift to Lichess for game volume and community, then return to specific Dark Squares modules when long diagonals, knight forks, or quadrant tracking slip.
Choosing the right platform for your needs
Pick based on current skill, goals, and learning style. A 1200-rated player building visualization from zero needs different tools than an 1800-rated player chasing tournament points. Choose for where you are, not where you hope to be.
Start with a baseline check. Can you “see” the board with eyes closed for a few moves? Do square colors come instantly, or do you compute them? If h6 takes thought, Dark Squares drills will clear that bottleneck faster than more games will.
Match platform to goals. If you want rating gains soon, you need practical application on Lichess. If you are preparing for a blindfold simul or building cognitive capacity, prioritize Dark Squares’ systematic development for 6–8 weeks before heavy gameplay.
Matching learning style to platform structure
Repetition lovers who want visible progress graphs and clear targets fit Dark Squares’ metrics and structure. Context-driven learners who understand skills best through immediate consequences fit Lichess, where mistakes cost material and games, and feedback arrives instantly in analysis.
Structure versus freedom matters. Dark Squares enforces a plan with thresholds and sub-skill focus. Lichess offers flexibility to experiment with time controls, openings, and opponents. Choose the path that keeps you practicing consistently.
Budget and time commitment realities
Lichess costs nothing. Spend a week on blindfold games and decide if the format excites you. If yes, a Dark Squares subscription often compresses two months of focused fundamentals into fewer hours than six months of casual play would require.
Time blocks differ. Dark Squares excels in 10–20 minute sessions with natural stopping points. Lichess blindfold games take 15–60 minutes, depending on controls. If your schedule offers short windows daily, prioritize Dark Squares; if you have a few longer sessions weekly, stack Lichess games.
Starting your blindfold training journey
Begin on Lichess. Create a free account, open Board Editor, and play the computer in blindfold at 1+0. Ten games reveal your baseline: do you lose pieces from memory or from calculation?
If memory breaks, switch to Dark Squares’ square colors for 2–3 weeks, then add coordinates and knight routes before returning to games. If you can track the board but calculate slowly, keep playing 3–5 blindfold games weekly and target specific Dark Squares modules for the weak patterns you spot.
Signs you need to switch platforms
After 50 Lichess blindfold games, if blunders come from forgetting piece locations, you lack foundations; shift to Dark Squares for drilling. If you’ve cleared all Dark Squares modules but still collapse under time, you need more Lichess game reps and pressure.
Key takeaways
Dark Squares builds fundamentals fast with adaptive drills, analytics, and thresholds; Lichess applies skills through real games and analysis.
Under ~1400, start on Dark Squares; 1400–1800, mix drills with games; above 1800, play mostly on Lichess and patch gaps with drills.
Short, frequent sessions favor Dark Squares; longer, fewer blocks favor Lichess blindfold games and post-game analysis.
Use metrics to avoid plateaus: switch platforms when errors come from memory (drill) or pressure (play more games).
A hybrid plan wins: drill square colors and coordinates to speed, then stack Lichess volume and revisit drills for specific leaks.
Your micro-action for today: Play one blindfold game on Lichess at 3+2 against the computer. Write down whether losses came from memory failures or calculation mistakes to pick your next step.
