About this game

Explore and master chess openings with this app in an innovative way.

Millions of chess games were analyzed to classify ECO openings by popularity, allowing to explore them visually on the board, and to remember them with a spaced repetition trainer.

With spaced repetition they will stay in your memory and will be easy to recall in live game situations.

The explorer also allows to visualize transpositions - how a ECO chess position can be reached with different lines, and how popular they are.

Opening explorer:

Discover and analyze chess openings easily

- browse thousands of opening variations of the ECO classification
- explorer popular lines reaching those positions
- quickly navigate from one opening to another
- learn common ideas and responses

Opening trainer:

Memorize chess openings easily and gain an early advantage in your chess games

- practice an opening repertoire adapted to your skills
- train opening moves until they become automatic
- reinforce correct moves with spaced repetition
- improve recall of lines in an interactive way
Master chess openings: explorer, repertoire builder & spaced-repetition trainer.
