Just like your body, your brain gradually declines if it isn't used.
To stay youthful and keep your mind sharp every day,
start a "daily brain health habit" right now—easily, using just your smartphone!

There are no difficult controls or complex rules.
The gameplay is simple: just tap the screen with a single finger. Even seniors or those not confident with smartphones can enjoy it immediately without any confusion.

◆ Four great features that make you want to keep playing every day!

① Just a few minutes a day! Perfect for spare moments in the morning or during a break.
Simply play once a day—it feels just like flipping through a newspaper.
You can easily keep up the habit during spare moments, such as while waiting for a train, between household chores, or during your relaxing time before bed.
As you continue playing, you'll unlock even more brain-training games.

② "Reward Stamps" on your calendar & daily missions.
Play once a day, and a stamp is marked on your calendar.
Plus, clear the "Mission of the Day" to earn a "Medal" reward!
The sense of accomplishment from seeing your stamps line up, combined with fun daily missions, makes it easy to turn this into a natural daily routine.

③ Exchange collected medals for your "favorite stamps"!
Use the medals you've saved up to trade for stamps featuring various designs in the shop.
You can switch up the stamps you use on your calendar to match the season or your mood, making stamp collecting even more fun!

④ See your progress with "Brain Age Checks" & "Performance Graphs."
The app includes a "Brain Age Check" to see your current ability at a glance, as well as "Performance Graphs" that summarize your daily results. You can stay motivated as you feel yourself growing day by day—saying things like, "I solved it faster than yesterday!" or "My mind feels sharper."

*Note: "Brain Age" is not based on medical evidence but is an estimate calculated using the app's own unique formula. Please enjoy it as a fun guideline for your daily mental exercises.
