EasyGo - Tsumego, SGF editor 1.9.8

EasyGo is a comprehensive go software that offers a variety of features to help improve your go skills and enhance your enjoyment of the game.

Key Features:

1. Extensive Bundle of Problems: EasyGo includes a collection of 2400 problems covering various aspects such as basics, life and death, tesuji, and endgame. Furthermore, the 893 problems on life and death have detailed variations to cater to all possible moves.
2. Diverse Study Methods: EasyGo offers multiple ways to study problems:
Problem Practice: Problems can be sorted based on total attempts, incorrect attempts, and win rate. The ability to randomize color and rotate the board adds further variety to your practice sessions. Problem Test: Take standard tests (20 problems in 10 minutes) or customize your own test by selecting the total number of problems and test duration. The bundled problem tests are integrated with the game center leaderboard, and your test history is automatically saved for later review. Spaced Repetition System: EasyGo incorporates a spaced repetition system (SRS), which functions similarly to a flashcard application. When presented with a problem, you rate your familiarity with it as "Fail," "Hard," or "Easy." The system then schedules future reviews based on your ratings, ensuring effective retention of the studied material.
3. Browsing, Editing, and Replay of Game Records: In addition to its problem-solving capabilities, EasyGo serves as a versatile SGF editor. It supports most commonly used SGF FF4 properties and boasts features such as a node tree view and a variation table. You can record your own games, create custom problems, and switch to problem mode for testing at any time.
