Overview

How sharp is your memory? Kanji Concentration is a card-matching game that challenges you to memorize card positions instantly and find all the pairs. Each card shows a single kanji on an abstract background that embodies its meaning, so you train concentration, instant memory, and kanji recognition at once. HOW TO PLAY 1. Memorize Phase: All cards are revealed for a limited time. Remember their positions! 2. Answer Phase: Cards are flipped face down. Use your memory to find matching pairs. 3. Find all pairs to clear the stage! DIFFICULTY - Easy (2×4, 10 s to memorize) / Normal (4×4, 5 s) / Hard (4×6, 3 s) - In Hard, card positions shuffle after the memorize phase - Endless mode: fixed 4×4 grid, one miss and you're out, with rising difficulty FEATURES - Rich Japanese-style design (ink black, golden yellow, vermilion) - Kanji are read aloud when you flip a card (can be turned off in settings) - Fully offline - No data collection, no ads - VoiceOver support

Support / FAQ

Frequently asked questions about Kanji Concentration and how to contact us.

  • A concentration (memory-matching) game played with cards that each show a single kanji. Unlike classic concentration, every card is first revealed face up for a limited time in the Memorize Phase. Once the cards flip over in the Answer Phase, use your memory to find the matching pairs. Clear all pairs to win.

    • Easy (2×4, 10 s to memorize) / Normal (4×4, 5 s) / Hard (4×6, 3 s): more cards and less time to memorize them.
    • Hard: card positions are shuffled after the Memorize Phase ends.
    • Endless: a fixed 4×4 grid where a single miss ends the run, with difficulty rising as you progress.

  • iPhone running iOS 17 or later.

  • No ads are shown, and there are no in-app purchases. The game is completely free.

  • Neither. The app works fully offline.

  • Your settings and your best Endless stage are stored on your device only. Nothing is sent to LFT servers. Note that deleting the app also deletes this data.
