Updates
Itte Dojo gets a little better every week. New features, improvements and fixes are listed here.
- BetterPrivacy: the usage counts now include how many times the position analyzer is run, and the privacy and analyzer pages say so. The position and the results are never sent.
- NewNew: the position analyzer. Set up any Reversi position, choose who is to move, and see the disc margin of every legal move with the best move and its line. With 18 or fewer empty squares it reads to the end, and the margins are exact when it finishes in time. Share a position as a link, or open one straight from any move in Review or from an endgame puzzle once it is solved.
- NewNew chess start page: how it works, the grading scale, and links to playing, the strategy guides, playing a friend and Practice. The Chess link in the top menu now opens it.
- FixReversi dojo: on phones, the grade line above the board could be cut off in English. It is shorter now and fits on one line.
- BetterPrivacy: the usage counts now include rank-check results (the rank level and the number of right answers), and the privacy and rank check pages say so.
- BetterReworked the home page: the sample now comes from a real graded game with its board, the first button opens an endgame position, and How it works comes before the list of dojos.
- FixBug fixes. Playing a friend: you now see right away when your opponent loses connection, and the page reconnects when your network or the tab comes back. Daily puzzle: the same puzzle no longer comes back a few days later as puzzles are added, and Everyone's results now count only the players of one day (Japan time). Chess: a mate threat now says mate, and the level and color you chose stay after a reload before your first move. Review now grades a move that draws by repetition (and similar draws) correctly. Reversi dojo: when a game ends with empty squares, the margin is counted the same way as the exact evaluation. Damaged saved data no longer stops the dojo, puzzle, daily puzzle or Practice pages.
- NewNew: the one-minute rank check. Answer five endgame puzzles of rising difficulty, 30 seconds each, and get a rank estimate and a title from how many you got right and how fast, with a result card you can share on LINE or X. Find it on the home page, the rank exam and the puzzle list.
- ContentThe rank exam page now lists how strong each of the eleven examiners is (how far it reads ahead, when it reads to the end, how much it wavers) and suggests where to start.
- BetterEndgame puzzles: on computers, a puzzle page, the daily puzzle and Practice now fit the whole board and the Show answer button on the first screen. Before, the bottom rows of the board could be cut off on shorter screens.
- BetterRank exam: on desktop screens too, you can now start an exam right from the bar above the board (the start button used to be below the fold). While the bar is shown, the board is a little smaller so the whole board still fits on the first screen.
- BetterPrivacy: the anonymous usage counts now include Master of the Week games (started, the result, and which Master), so we can tune each Master's strength. The moves of your games are never sent; the privacy page has been updated.
- NewNew in the rank exam: the Master of the Week. Each week a computer with a habit, such as grabbing corners or flipping as many discs as it can, takes the stage. Read its habit, win, and you get a certificate with the Master's seal. Games against a Master do not count toward your rank.
- BetterPrivacy: the anonymous usage counts now include whether the screen is phone-width or wider (just those two classes), so we can tell whether phone improvements help. The screen size and device model are never sent; the privacy page has been updated.
- BetterReversi dojo: on phones, the grade for your move (verdict, best move and loss) now appears right above the board, and Details jumps to the full explanation. When the game ends, the result shows there too.
- BetterRank exam: on phones you can now start an exam right away from a button above the board, which also shows the rank and color you will play.
- ContentNew: "How often is parity right?" We solved every move in endgame positions with 8 to 14 empty squares and measured how often the parity rule picks the best move, with an example where it fails.
- NewPass a rank exam and you now get a certificate image with the final position and disc count, ready to save or send on LINE or X.
- ContentNew: chess strategy guides. Five illustrated guides on the center, piece activity, king safety, pawn structure and basic endgames, linked from the chess dojo.
- ContentThe parity guide now starts with a three-empty exercise. Choose a first move, step through the finish, and compare how move order changes the result.
- BetterDaily puzzle: after you answer, see how many players tried it and how many solved it on the first try.
- NewNew: the daily puzzle. One endgame puzzle a day, with a streak counter and a result you can share with friends.
- BetterReview: you can now switch to your opponent's moves and see their grades and best moves too.
- NewNew: the rank exam. Play computers of 11 strengths from 10 kyu to 5 dan with no hints or take-backs; win to earn the rank.
- NewNew: the opening drill. Play named openings as Black or White from memory; lines you miss come back for review.
- NewAdded this update history. Weekly improvements will be listed here.
- NewFriend matches: the number of spectators is shown, spectators can send cheers, and stamps and cheers are kept in a message history.
- BetterFriend matches (Reversi): the board can also show where your opponent can play (optional).
- BetterFriend matches: your own name is shown, and a friend who joined by the link can set a name during the game.
- FixFixed "This review link is not valid" when reviewing a Reversi game.
