九九リス　九九のゲーム（ドリルではない真のゲーム）

Let's start with a "trial"...
・ You can "trial" for free from the following site.

If it seems to work...
・This app is free. There are no ads or in-app purchases (purchases). I would appreciate it if you could install the app and give it a try.

subject
・Elementary school students and their parents who want to master the multiplication table perfectly.
・ Everyone who wants to do a little brain training in their spare time

what kind of game
・Make a multiplication (99) formula with the falling numbers and erase it.
・If you erase one, you get 3 points. If you are lucky, you will get 2 bonus points. If you make the same formula, you will get 1 point from the second time.
・The image changes every time you score. (100 sheets from 0 to 99)

manner
-Tap "Start" to start the game. "Reload" when stopping in the middle.
・The numbers move left and right with the arrows (⇦ ⇨). (⇩) to fall at once.
・Unnecessary numbers can be thrown in the trash can with (⇧). (up to 5)
・When the trash can is full, you can reuse the trash. With (⇧), the falling number goes into the trash can, and the trash at the bottom comes out instead. (However, it can be reused up to 99 times.)
・The numbers in the 2nd column from the left will change to a multiplication sign "x", and the 4th column will change to an equal sign "=".
・If the answer is one digit, it is necessary to put "0" in the tens place, such as "06" and "09".
・Although it is not in the multiplication table, it can be multiplied by 0. However, there are no bonuses.

others
・The falling speed of the numbers gradually increases, but returns to normal when it becomes very fast.
・If the number does not reach the bottom, it will not be judged. (The formula will not be completed during the fall)
・The ceiling (upper wall) falls down one step every 99 seconds. (up to 8 steps)
・If the reuse point is less than 99, the ceiling will be lifted one step when the bonus is scored, and after the reuse point is 99, when 3 points are scored.
・Wrong formulas remain, but you can erase them together by completing the formula on the upper row and erasing it.

How to capture (This is the basics. Please discover your own method.)
・Falling numbers, next numbers, garbage numbers Find combinations that can make a multiplication formula from a total of seven numbers, and arrange the numbers in the field using the reuse function. "×" can be made, but "=" is not yet made. Repeat the work and build up the formula.
・If you can't make a multiplication formula, make a form in the field that waits for one of the numbers. Then put an ``='' to erase one expression, and the trash will be cleared, giving you a greater chance of getting the number you're waiting for.
・Let's aim for over 99 points by making full use of "discovery power", "decision power", "concentration power", and "luck".
