You know maths? There's divide, multiple, add and subtrate. And yes, we are talking about the multiplication in maths.
For example, your core number is 2. Multiples of 2 are 2, 4, 6, 8... You will need to use addition for your border and entry coins to get the multiples. Now you have 2 for your entry coin. Select it. The twinkle sound will be heard and you get a Core Break written across your screen and the next turn comes. You have achieve the multiples by selecting the correct number.
You do not get quota just using the entry coin. You will need to use border coins to add on your quota. For example, your core number is 7. Your entry coin only has 2,3,5 and 6. Select 3. There's no core break because you have not reach the criteria! Next, you have the choice to either use the border or the entry coins. Select 4, the border coin. 4+3=7. You reach the criteria! The twinkle sound comes, and Sphere Break! You used one border coins. So you will have one quota. Collect as much quota as possible before the set number of turns ends.
Techniques to win a game
Just getting the multiples per turn is NOT enough to get the required quota. Even if you are lucky, you can't meet a quota of 40 in 15 turns! Thus, you will need to do combos.
Coin Count Echoes
This is like a combo. For example, you use two coins to have a core break. Second turn comes in, you use two coins to have a core break again. By right, you should have only 2 quota right? Wrong! Since you use the same amount of coins for two turns, you did a coin count echo. Number of border coins you used X number of consecutive echo So in this scenario, you have the first echo. 2 X 1 = 2! You will get 2 bonus points for that turn.If the next turn, you use a different number of coins, you will break the echo, and start all over again. Build up the amount of echo, then getting quota won't be a big problem!
Multiplier Echoes
When making a core break, if you use that same multiplier as you used in your last turn, you receive bonus points for quota. For example, you have a core number 2. 2,4,6,8... You have a sum of 8, core break. Next turn, you have a core number 3. 3,6,9,12... You make a sum of 12, core break. 8 and 12 is a multiple of 4. In this case, you will get a echo bonus. Target multiplier X number of consecutive echoes In this case, 4 X 1 = 4. You will get 4 bonus points for that turn. This is a great way to get in quota. Even though the coin combo echo is easy to do and understand, mastering the multiplier echo technique could get you more quota and meeting 100 quota won't be a problem.
