Kanji Builder

KanjiBuilder is a kanji building game inspired by exercises found in a textbook called "漢字・語彙が弱いあなたへ". You are given a reading and meaning of a kanji, and you must "build" it by selecting the correct kanji parts it is composed of.

Other game modes include:
* jukugo (compound word) builder, where you are given a part of a jukugo and the reading and meaning of it, and you must select the correct kanji that comprises the full jukugo.

* jukugo kanji parts builder, where you are given a part of a jukugo and the reading and meaning of it, and you must select the correct kanji parts that comprise the missing kanji of the full jukugo.

* single-reading phonetics: you are given a phonetic, its reading, a part of a jukugo and its reading and meaning, and you must select the correct kanji part(s) that together with the phonetic comprises the missing kanji of the full jukugo.

* mixed-reading phonetics: same as above, but these phonetics have multiple possible readings, not just one.

* lookalikes: you are given a reading and meaning, and you must select the correct kanji among all the similar-looking kanji.

You can limit the span of the kanji/jukugo generated to/up to/down to a specific school grade (from 1st grade of primary school up to high school); to a specific JLPT level (N5 to N1); KanKen level (10 to 2); and James Heisig's Remembering the Kanji (RTK) index (4 to 2195).

There are both practice and test modes available with hints. You can also choose to decompose and build kanji with either 2 or 3 parts.
