About this app

"Route 21" is a series of brain training apps that you can easily enjoy in your spare time.
There are no forced ads during gameplay. It also works offline (without network coverage), so you can train at your own pace regardless of location, such as while traveling or underground.

■ Train Your Brain with 3 Genres
This app offers three genres: "Calculation," "Logic," and "Memory." Each has a different play time, allowing you to choose the mode best suited to your spare time.

① Route 21 (Calculation)
Within a one-minute time limit, tap the numbers on the board to match the sum of the numbers to the target value. Quickly find the correct answer from 18 cards and clear stages one after another to aim for a high score.

② Sudoku 21 (Logic)
Fill in the numbers according to the rules of Sudoku, aiming for combos by making the sum of the entered correct numbers exactly "21." Utilize strategic stage skipping to compete for the highest score across three stages.

③ Memory 21 (Memory)
This is a memory puzzle where you must memorize the arrangement of all cards in the first 5 seconds and make the sum of the numbers you flip over "21". If you can't remember, you can use the "Hint button" to re-memorize. Sharpen your concentration and aim for the final stage with consecutive correct answers.
