V1.7.2 Feb. 27, 2015


• Added a Joseki practice mode, which is similar to the problem pratice, however you have to practice all the variations one by one. As the demo of the new Joseki mode, 32 common invasion patterns(Joseki) are added to the bundled system library, please have a try. Joseki mode for the problems under "My Games" is also supported. Added a Joseki game type for game edit, Joseki type is special mode of problem type. For problems with Joseki type, after walking through one variation, you're prompted to try all the other variations one by one. If all the variations have been tested, the side will be switched and all the variations from the other side will be tested again. Currently there is another difference between problem and Joseki type, for the problem type, all the variations are wrong varations except main line. You have to put "right" or "correct" in the comment of the last move of the varaiton to mark it as correct variation; For the Joseki type, all the moves are correct by default. please long tap the node in the tree view to toggle it as bad move.

• Two finger tap to switch side during problem practice

• for the problem mode, the system will play the next move for you, and ask you for the move after that

• for the new Joseki mode, the current position will jump to the first move.

• Now the game type info(normal game, problem or Joseki) is saved in the exported SGF file, and the game type will be kept after importing.

• Shows file name in the list/grid view if the game name property(GN) is an empty string or string with only space. Added an option to force show file name instead of game name property.

Bug Fixes:

• After creating a problem from scratch, if switch to problem test without saving first, then when switch back to game edit mode, the game is gong.

V1.5 Jul. 1, 2013


• Add a problem test mode, and the previous problem test is now called problem practice. In the new problem test mode, you can take standard test(20 problems in 10 minutes) or custom test, in which you can customize the total problem number, test time. During problem test, the restart, try, show solution button are all disabled. The standard tests for the bundled problems are integrated with game center leaderboard. Test history is saved automatically. And you can review all the problems answered incorrectly in any test later.
• Problem practice: instead of responds with random variations, the opponent now by default responds to first variation first, after you have solved the problem once and tap the restart button to retry, the app will responds randomly if there are multiple variations.
• Add an option to show alternate moves in problem mode or game mode. The alternate moves are marked with a solid blue rectangle. In problem practice mode, if long tap the alternate move mark, the opponent’s move will be changed to that position. That is, you can choose which variation the opponent will respond.
• The function of the "show answer" button during problem practice has been enhanced. Now, tap the button will just show hint for the next move: actually show all the correct variations (green dots) and incorrect variations (red dots) for a while. Long tap the button will show the solution automatically. Instead of just show the main line in the previous versions, now you have the option to control how the solutions are shown: Main line first, then random (default);Main line only; Random

(Please note, the stats for SRS are still not aggregated now, and reset statistics won’t reset the stats for the sub folders)
• When use "Open In" to handle a game to another application, the fixed name openinfile.sgf is used in previous versions. Now the original file name is used if the game was imported. Or the SGF game name property(GN) will be used if the game is created from scratch in EasyGo.
• If a game is imported via paste SGF from clipboard, then the export file name is fixed to new.sgf in previous versions. Now the game name(GN) property is used as the file name.
• Changed the smallest auto replay interval to 0.3 second from 0.5 second
• Add an option to display coordinates in bold font.

• Grid view (thumbnail view) has the same sort options as list view. The option can be set in either view and the chosen option is kept when you switch back and forth between views.
• Changed the default stone image. "Big stone" is now on by default.
• Random rotate/swap color and double tap to zoom can be configured in game settings as well as in global settings. The chosen settings still apply globally.
• Either "right" or "correct" can now be used in the comment of the last node to mark the correct variation. The key word is case insensitive and can be surrounded by other words. For example, “Ko is correct.”

V1.1 - Mar. 1, 2012


  • Performance tuning: the time takes to import games, batch delete has been reduced significantly.
  • Sort game/problem by black name, white name, game name, date
  • Shuffle game/problem(especially useful for problem practice)
  • Search game/problem by black name, white name, game name, date
  • For problem practice, randomly select one of right variations to test whether you know all the response to the opponent's move instead of always use the first variation
  • For problem practice, the "next/restart" button on the board is now semi-transparent
  • (iPad Only) Added a full screen game edit view for landscape mode, two finger tap the tree view to activate. Supports two layout schemes, two finger tap the tree view to toggle.
  • Add a variation table view to complement the tree view, node name(if any) will also be showed
  • Add an option to toggle the showing of next move marker: always show, never show, show only there are variations
  • Add a button to back to the most recent branch point
  • Add a copy to clipboard button in show SGF window
  • In game view settings, removed three sliders to adjust view size, now you can drag the resize handle to adjust the size of board, comment, tree, variation table view.
  • During import, if tap cancel button, a confirm window will show, you have the options to continue importing, or keep the current imported file or just delete all the imported files.
  • In Version 1.0, when importing big files, the UI is not responsive for a while after tap the import button, this was fixed in Version1.1

Bug fixes:
