Choose your challenge
Play White or Black against an unrated practice opponent, with Foundation, Intermediate, or Advanced settings.
If you can’t follow a chess book
without reaching for the pieces,
that’s a
visualization problem—
not a talent problem.

THE ULTIMATE TEST
How many moves can you follow before you lose the board in your mind?
Blindfold Game
A separate full-game mode beyond the ten training levels. Play a complete legal game with the pieces hidden. Keep the position from the notation, speak your moves, and reveal the board when you need to reconstruct it.
Speak naturally
Call moves and castling. Clarify the starting square when two pieces could make the move.
Rebuild and resume
Use reveals, redo a misheard move, and return to your saved unfinished game.
Train with fewer reveals
Foundation offers unlimited reveals. Intermediate and Advanced let you earn them as you play.
Start here after installing
Begin with Training Level 1. For a guided 8–12 minute practice session, open My Training → Daily Session. Blindfold Game brings your skills together in a full game.
THE BOARDWITHIN DIFFERENCE
See it. Think it. Say it.
Use your voice to answer supported exercises. Picture the answer, then say it out loud.
When a prompt appears, you visualize the answer and say it out loud. Voice recognition checks your response and moves you forward. That creates a tight learning loop between seeing the board, recalling the coordinate or move, and expressing it correctly in chess language.

WHY VISUALIZATION MATTERS
Chess books and lessons often ask you to picture a position.
Books, courses, and lessons are filled with notation. With practice, players can read a move like Nf3 or Bb5 and picture what changed. If that is difficult, a board can help you follow along.
That usually means stopping the lesson, setting up a board or opening an app, moving the pieces manually, and then returning to the material. It works—but it is slow, breaks concentration, and makes it harder to absorb the ideas being taught.
FROM NOTATION TO VISUALIZATION
Stop reconstructing every move.
Start seeing the position.
BoardWithin is designed to close the gap between reading notation and actually visualizing it. Through repeated coordinate, piece-location, movement, speed, and tactical exercises, the app gives you practice in building an internal chessboard.
The goal is to connect notation with a position you can picture, hold, and update mentally.

THE SKILL UNDERNEATH THE LESSON
Train the mental board first.
Chess books and courses can teach strategy, openings, and tactics—but you get more from all of them when you can hold the board in your head. BoardWithin trains that ability deliberately, one repetition at a time.
01
TRAINING LEVELS
Build your internal board map.
Build the internal map first. Training begins with coordinates and gradually removes visual assistance, giving you repeated exposure to squares, piece locations, and legal movement patterns until the board becomes familiar without labels. Then take your hands off the screen. In Voice Mode, BoardWithin prompts you and listens for the answer—so you can name a square, or identify its color and piece in Square Recall. Full move entry, such as “Knight to e5”, belongs to the mate-training levels, Puzzles, and Blindfold Game.
- Structured training path: ten levels covering coordinates, movement, Square Recall, Piece Recall, and hidden-piece mating endings
- Hands-free Voice Mode: answer squares, color-and-piece questions, or moves as the exercise asks
- Labels disappear as your internal map develops
- Coordinate, piece-location, and movement recognition
- Custom board and piece themes
STRUCTURED TRAINING PATH
From seeing the board to seeing it in your mind.
Ten levels build coordinates, movement geometry, recall, and playing simple endings to checkmate with the pieces hidden.
GOAL Blindfold Vision
01
Notation Basics
Find and name coordinates on a labeled board from White’s perspective.

RAPID CHALLENGE
Rapid Challenge: chess coordinate practice.
Practice recognizing squares against a shrinking reaction window. Average response time, streak, and Recognition Score track your performance in this drill. Choose Tap or Voice, and select White, Black, alternating, or random orientation. In Voice, name the marked square; a correct answer advances the challenge.
- Starts at a manageable 4.00-second window
- Each correct answer removes 0.1 seconds, down to a 0.35-second minimum
- Hands-free speed training: call out answers against the reaction clock
- Current streak, best time, and average time
- Clear progress tracking over time
RECOGNITION SPEED IS ONE PART OF BOARD VISION
03
POSITION RECALL
Position Recall: chess memory training.
Position Recall trains your memory of piece locations. Study a real position, remove the visual reference, and reconstruct the board from memory. The goal is not to name coordinates—it is to hold an entire position in your mind.
- Study positions before the board is hidden
- Reconstruct piece locations from memory
- Train from both White and Black perspectives
- Build the position-holding skill used in calculation and blindfold play
04
PUZZLES
Solve chess puzzles from memory.
Puzzles turn visualization into calculation. BoardWithin includes 100 curated tactical puzzles from Lichess, rating-sorted from beginner to extreme difficulty. Instead of simply recognizing the board, you learn to spot recurring tactical ideas, hold positions in mind, process the opponent’s response, and visualize the continuation.
- 100 curated puzzles across a Beginner-to-Extreme tactical progression
- Progressive study window, then pieces hide so you calculate from memory
- Forcing moves with automatic opponent replies
- Tap/drag or voice move entry
- Repeated exposure to forks, pins, skewers, captures, mating patterns, and coordination
- Solve-time and streak tracking
THE TWO SKILLS WORK TOGETHER
Visualization lets you see it.
Pattern recognition helps you find it.
Strong chess calculation is not just about looking farther ahead. You also need to recognize what matters. BoardWithin combines repeated visualization training with curated tactical puzzle repetitions so the board becomes easier to hold in your mind and important tactical patterns become easier to recognize.
VISUALIZATION
See the position.
Know where the squares and pieces are. Follow moves mentally. Hold changing positions in your head without rebuilding every move on a physical board.

PATTERN RECOGNITION
Recognize what matters.
Solve 100 curated tactical positions and repeatedly encounter the structures that decide games. With enough repetitions, familiar tactical ideas can become patterns you recognize faster.
VISUALIZE THE BOARD

FIND STRONG MOVES FASTER
The goal is repetition with purpose: build a clearer internal board, then expose yourself to enough tactical patterns that you can identify promising ideas more quickly when similar structures appear in real games.
BOARDWITHIN
Build the board within.
See more in every position.
Train visualization deliberately—by sight, by speed, and hands-free by voice—to practice following books, courses, puzzles, and calculation in your head.
