ChessRiddle is not your average tactics trainer. Instead of guessing single moves, you train real calculation – as close to a real game as possible. WHAT MAKES CHESSRIDDLE DIFFERENT • The board stays static: you calculate the whole line in your head instead of trying moves on the board. • You enter the complete variation tree to prove you calculated the entire line – no move-guessing. • Mixed Mode: tactics and positional play combined, just like a real game – you first decide whether the position is tactical or positional. • Every solution is validated server-side with Stockfish. That sets ChessRiddle apart from the hundreds of pure tactics trainers where a well-guessed first move is enough. SIX TRAINING MODES • Tactics – Find classic combinations and tactical motifs • Mixed – Tactics and positional play in one mode: assess first, then solve – just like at the board • Pieceless – Solve puzzles without visible pieces and train your board vision • Visualization – Calculate announced moves (pre-moves), then solve the position • Opening Blunder – Spot and punish typical opening mistakes • Position Evaluation – Estimate who stands better TRAINING PLANS Structured training sessions of warm-up, main part and cool-down – automatically assembled by duration and focus. COLLECTIONS Build puzzle collections and edit them in bulk – for your own training or for students. TRAIN TOGETHER In a shared session a trainer and a student work through the same positions. DUELS Challenge a friend to the same puzzles at your own pace. The more accurate player wins, not the faster one. Full history and a faster way to create a duel. NOTIFICATIONS Get notified about duels, friend requests and shared sessions. COORDINATES TRAINING Sharpen your board vision: find and name squares – timed or as a streak. PERSONAL RATING Track your progress with an individual rating system. Every mode has its own rating, so you can target your weaknesses. DETAILED STATISTICS Analyze your performance with in-depth statistics and follow your development over time. LEADERBOARD Measure yourself against other players and climb the rankings. STREAK MODE Solve as many puzzles in a row as you can without a mistake and keep your streak alive. FRIENDS Connect with friends and compare your stats. ENGINE ANALYSIS Analyze positions with the built-in Stockfish engine. HISTORY Revisit solved and missed puzzles to learn from your mistakes. With Practice Mistakes you replay exactly the positions you got wrong. ChessRiddle is the ideal app for chess players who take their training seriously and want to improve in a game-like way – from beginner to advanced. Train like you play. Prove your calculation.
