Grid Recall

Take a look at the nine palaces and get into your heart!

In Grid Recall, memory is no longer just a linear sequence, but an accurate test of spatial layout and visual coding ability. The system will show a 3×3 number nine squares-nine positions and nine numbers, which are arranged clearly but fleeting. You need to remember the location of each number in a limited time, and then enter all 9 digits completely after the grid disappears.
Grid Recall is derived from the classic spatial memory paradigm, which is suitable for students to improve their concentration, professionals to exercise their information integration ability, or any player who pursues mental sharpness. A few minutes every day, let your brain be between square inches, and practice the ability to never forget.
