Chess Visualization is a complete training gym for the skill that decides many games: seeing the position before it appears on the board. THE BLUNDER CURE Many games are not lost to brilliance. They are lost to a piece left hanging. How can you blunder a piece next move when you have trained yourself to see many moves past it? Blunders are failures of sight, not knowledge — build the habit of looking further than your opponent and they quietly disappear from your games. SEE FURTHER THAN YOUR OPPONENT Visualize from 2 moves ahead up to 25, with audio read-back of every move so you can train your calculation with your eyes off the board. OVER 1.3 MILLION PUZZLES, ALWAYS OFFLINE The entire puzzle library lives on your device. Train at 35,000 feet, on the beach, or anywhere without a signal. FIND YOUR LEVEL AND CLIMB Rating ladder groups serve up random puzzles sorted into 200-point Elo bins, from under 600 all the way past 3000. Find your level, train slightly above it, master it, and move up. Difficulty also scales across five presets: Beginner, Intermediate, Advanced, Expert and Titled Player. TACTICS, OPENINGS AND MATING PATTERNS Advanced tactical themes including collinear moves, deflection, interference and many more. Plus 19 distinct checkmating patterns, mate-in-1 through mate-in-5 challenges, and puzzles from 31 popular openings. ENDGAME MASTERY Many pre-defined endgame categories such as "King + 3 pawns vs. King + 2 pawns" or "Rook + 2 pawns vs. Rook + 3 pawns". Optionally play them out against the built-in engine until the technique is automatic. ENGINE ANALYSIS A built-in chess engine lets you analyze any position after you solve it, so you understand not just the answer but the reason behind it. LEARN FROM YOUR MISTAKES Every puzzle you miss is automatically collected in a dedicated group for review and repeated training, so weaknesses become strengths. STAY MOTIVATED A unique badge reward system tracks your progress and keeps you coming back to train. MAKE IT YOURS Customize your home view and pin only the puzzle sets you care about for instant access to your favorites. ON IPHONE AND IPAD Designed for both screens, with a large board and side panels on iPad. Your training statistics sync through iCloud, and one Premium subscription covers both devices.
