The game is viewed primarily through the Nintendo DS Touch Screen. Players write answers with the stylus, read passages aloud for certain exercises, and solve timed tasks involving numbers, words, symbols, and memory.

Daily Training presents a limited set of exercises and records the result in the player's calendar. Practice and Brain Age Check modes provide additional ways to repeat activities or measure performance. More exercises and features become available as the player returns on later days and earns stamps.

Use the stylus lightly and write clearly, especially in recognition-based activities. Read instructions before starting, because some tests measure speed as well as accuracy.

• Practice arithmetic and reading regularly rather than repeating only the easiest exercise.
• Keep sessions consistent and avoid rushing through answers that require careful listening or writing.
• Treat the brain-age number as a progress indicator, not a scientific diagnosis.
