Review four-character idioms in a game-like way with randomly selected questions, replays of incorrect answers, and a hall of fame system. Perfect for vocabulary learning during spare moments.

"Ebi-Yo" is a learning app that lets you repeatedly learn four-character idioms in a game-like format. It's designed so that you can work on four-character idiom problems, repeatedly review incorrect answers, and check what you've learned after a period of time. It can be used for memorizing and reviewing four-character idioms, and for vocabulary learning during spare time. ◆ Features of Ebi-Yo 【Random Questions for Repeated Learning】 Four-character idiom problems are presented randomly. Instead of just memorizing the same order, you can challenge yourself with problems repeatedly. 【Incorrect Answers are Revisited】 Problems you answered incorrectly are presented again, so you can review difficult idioms without leaving them unresolved. 【Correct Answers are Revisited After Time】 Even if you answer correctly the first time, you can check it again after a period of time. You can check your memory through repeated learning. 【"Hall of Fame" for 4 Consecutive Correct Answers】 If you answer the same problem correctly four times in a row, you'll be inducted into the Hall of Fame. You can learn while feeling a sense of accomplishment as your memorized four-character idioms increase. [Achieve over 70% Hall of Fame status to unlock the next stage] As you progress through your studies and your Hall of Fame status exceeds 70%, the next stage will be unlocked.
