App Description

Japanese, English & Vietnamese word games for kids. A brain workout for adults.

KotoVelluna is a playful vocabulary app for children from age 2.

Look at pictures, listen to words, and connect them in a word-chain puzzle. The app supports learning Japanese, English, and Vietnamese.

■ Learn with pictures and audio

Tap a tile to see a picture and hear the word. Children can become familiar with words by looking and listening, even before they can read.

■ Play a word-chain puzzle

Move neighboring tiles to connect the end of one word to the beginning of the next. Pictures and audio provide helpful clues while children play.

■ Choose settings for each child

Listening and word-chain levels can be selected separately. A letter-helper setting lets parents adjust the amount of support.

■ Make time to think in the age of AI

As AI becomes part of everyday life, make time for children to think for themselves.

Word-chain puzzles put your thinking to the test as you recall words and work out which ones connect. With pictures and audio as clues, children can ask, “Which word comes next?” and enjoy that “I did it!” moment when the words fit together.

Reduce the letter clues to enjoy the puzzle as a listening and memory game.

It’s not just word play for children—it’s a fun brain workout for adults, too. Why not put your heads together and enjoy some family puzzle time?

The free version includes 15 listening words and 20 word-chain words in the base learning language. It is not a time-limited free trial.

Premium is a paid monthly or yearly subscription that gives access to all words and levels in Japanese, English and Vietnamese.
