Do you ever find yourself unable to say what you want to say?

This game is optimized for learning carefully selected four-letter idioms. By not broadening the learning target too much, the four-letter idioms will be engraved deep in your memory, and you will be able to learn them so that you can use them at random times.

There are mini-games between each level to review the main game. By playing repeatedly, the knowledge of four-letter idioms will become deeper.

You can play 5 levels for free, but you can play all 30 levels by paying.

It is a learning tool that allows you to learn like a game anytime, anywhere.
