Grade starts with D, and changes into C, B, and A according to the score.
The numbers turns unknown (white square) after some changes, which becomes earlier as grade ups.

When the game is over, the player's ID is displayed on the screen. ID indicates the level of your intelligence, particularly the capacity of your working memory, among a population, which could possibly be the entire humans in the 21st century on the planet.
ID is determined according to the game's pattern level, line level, and score.
A deviation is an indicator of a person's ranking in the population. It is often used in Japan to represent students' school performances. ID (Intelligence Deviation) resembles IQ (Intelligence Quotient), which may be better known globally. The comparison between ID and IQ is as follows.
ID | IQ | Rank | Statistical meaning |
---|---|---|---|
20 | 55 | 999th of 1000 | m-3s | 30 | 70 | 978th of 1000 | m-2s | 40 | 85 | 842nd of 1000 | m-s | 50 | 100 | 501st of 1000 | m | 60 | 115 | 159th of 1000 | m+s | 70 | 130 | 23rd of 1000 | m+2s | 80 | 145 | 2nd of 1000 | m+3s |
