GalaXXy brain

*For the remix, see galaXXy brain (Neutral Moon Remix).*

## Story Context

While the group are practicing their new song, “galaXXy brain”, a Noise Beast intrudes.

## Level Gimmicks

In the chart, there are many math problems that show up during the song. There are 4 different types of questions: arithmetic, “Which one is prime?”, “Which one is divisible by X?”, and a final solve for X equation at the end of the song. To answer these questions, a set of 4 notes with numbers scroll down from the top of the screen that require you to tap the right note(s) that has the same number as the answer to the problem. If you answer the question wrong, you take damage. How hard the math problems are and how many answers you have to tap at once scales on the difficulty of the song.

## Strategies

For “Which one is divisible by X?” questions, there are some divisibility rules that you can use to quickly find out if a number is divisible by another:

 3
 4
 5
 6
 7
 8
 9

For “Which one is prime?” questions, you can either use the tricks for divisibility or memorize some of the prime numbers. Since the answers are all under 100, you only need to memorize the first 25 prime numbers:

For the quadratic equation in Hard Verse 4, it is recommended to solve it by factoring:

```
ax2 + bx + c = 0
(px + q)(rx + s) = 0

x^2 - 2x - 15 = 0
(x + 3)(x - 5) = 0
(x + 3 = 0) or (x - 5 = 0)
(x = -3) or (x = 5)

```

These programs will help train your reaction time and solving speed with the same questions used in galaXXy brain. The second one is for training the final question on the Overload difficulty:

* Trainer program by Supershocky
* Overload difficulty cubic trainer by Supershocky

Lowering your Scroll Rate on the game options helps with this song since it gives you more time to think about the answers.

Keep in mind that while you can pause the game to get more time for thinking, this will change all the answers to ”?”, so you will need to remember which answer was which as well.

♠♥ Somehow we'll make it through
♦♣ A path will open to a brighter future
♦♣ New worlds arise for you
♠♥ The courage driving us to new adventure
♦♣ I know we'll make it through
♦♣ When countless fates collide, galaxies within your mind
♠♥ Light years of void between us all
♠♥ But when we look inside, we'll find our hearts will resonate
♠♥ Our song will take us to a new dimension

♠♥ A close encounter lights the spark of friendship
♠♥ New worlds arise for you

 A sea of shining lights, reflecting in your eyes
When countless fates collide, galaxies within your mind
Hand in hand, we'll win this fight
