This is a word chain game designed for elementary school students.
Players naturally learn vocabulary while exchanging words one-on-one with a calm AI teacher.
■ How to Play
Determine the order using Rock-Paper-Scissors and take turns chaining words.
You lose if you cannot think of a word to say or exceed the time limit.
You can speak words by pressing the microphone or by typing them in directly.
■ Three Difficulty Levels Tailored to Children
· Easy — Time limit 30 seconds, 3 hints. The game focuses on easy words the child already knows.
· Medium — Time limit 25 seconds, 2 hints. It balances fun with competition.
· Hard — Time limit 20 seconds, 1 hint. You find a strategy to beat the AI in advance.
Difficulty levels depend not on whether the AI makes mistakes, but on which words it chooses.
At any difficulty level, the AI accurately speaks only words that follow the rules. ■ Vocabulary Learning That Doesn't Interrupt the Game
There is a [Meaning] button next to every word. Since the meaning is displayed only when pressed, the flow of the game is not interrupted.
If the word is of Sino-Korean origin, the Chinese characters are also displayed.
For definitions, the definitions from the National Institute of Korean Language's Basic Korean Dictionary are used first to make them easy for children to read.
When the game ends, along with the number of words used, the number of incorrect words, the number of hints used, and the average response time,
the game briefly reviews the single most difficult word of the day.
■ Preventing Children from Getting Stuck
· If a word is incorrect, only the reason for the error is explained, and the child can say it again as many times as they want within the time limit.
· The answer is not revealed upfront. It is revealed only when the hint button is pressed.
· Supports the initial consonant rule. Saying 'nakyeop' after 'yeonrak' is accepted.
· For 'one-shot words' that have no words to follow, the game automatically looks up the dictionary to determine the answer.

■ Vocabulary Sources
For vocabulary, definitions, and Hanja information, we used publicly available data from the National Institute of Korean Language's Standard Korean Dictionary and Basic Korean Dictionary.
Take turns connecting words with the AI teacher. Speak them out loud, and immediately check the meaning of any words you don't know.
