The game builds an 8 by 6 board from the kana modes and categories you select, then duplicates cards into pairs and adds random obstacles. Hiragana, katakana, and mixed mode are available, with selectable seion, dakuon, handakuon, and yo-on categories.
Two cards clear only when they show the same kana value and can be connected through empty cells with at most two turns, including paths around the outer border. Each match adds 10 points and the round has a 60 second timer. Voice playback uses the browser Web Speech API, so availability depends on browser support and user audio activation.
Common questions and answers about this topic.
Select two cards showing the exact same kana. They clear only when a path through empty cells connects them with no more than two turns; the path may also run around the outer border.
Choose hiragana, katakana, or mixed mode, then select from the kana currently provided under seion, dakuon, handakuon, and yo-on. You can enable whole categories or pick individual kana.
The game uses the browser's Web Speech API to read a card when you select it. Playback depends on browser support, an available voice, audio being enabled, and a user interaction; matching still works without sound.
The game detects the deadlock and shows a Shuffle button. It keeps the remaining cards and obstacles, moves the cards to new cells, and provides at least one available pair so you can continue.
