The (Similar) Kanji Imposter Minigame & Practice Tool just went live!
Emergency meeting! There is an imposter among… these kanji. In fact, they’re all imposters, except one. Your job is to pick the real one! That’s the game. And it’s out now. Hurray!
The Kanji Imposters minigame is all about fine-tuning your kanji recognition skills, by pairing a given kanji with its similar-looking kanji cousins. (Think 末 vs 未.)

There are two different modes, Practice, and High Score. In both modes, you’re given a kanji’s meaning(s), and are prompted to select it from the list of 2-5 kanji below.
For Practice, you may choose from your known (learned) kanji, N5, N4, N3, or N2 kanji. For High Score, the kanji sets are limited to just the JLPT levels.
In Practice, there’s no timer, score, or combo, and you can take as much time as you’d like to identify the correct character. For practice, you can choose the number of questions you’d like, and there is a toggle that lets you filter out correctly answered kanji from your previous session(s). So you don’t have to repeat the ones you find easy!
In High Score, you can pit your kanji-recognition skills against the rest of the community by attempting to pick as many correct kanji (from a pool of 50 random kanji within that JLPT level) as you can, as fast as possible. There is a multiplier bar at the top that starts at x1 and increases as you correctly select kanji. Once it goes above x1, it will begin to diminish quickly, so answer swiftly to increase your multiplier (up to x10) and keep your combo going!
Failing to pick the right answer on time will decrease the combo by 1. Picking the wrong answer will give you 0 points! So, in most cases, it’s preferable to make sure you pick the right one, even if your combo drops by 1 or more (as picking the correct answer will still give you points!).
For convenience’s sake, we’ve also added hotkeys for the kanji options. You can press 1,2,3,4,5 to select the corresponding kanji.
For both modes, after your session, you’ll see a results screen that will show you the number of kanji you identified correctly, as well as the kanji that you didn’t get right.
If you do well enough in a High Score session, you may even end up on the leaderboard…

So good luck, and happy kanji-identifying!
