Make 10s -keep your mind sharp app for iPhone and iPad

Choose a number and make 10! A simple yet profound puzzle game!
Have you ever made 10s with 4-digit numbers, such as a car number or a train ticket?
From elementary school students to adults, lets train your brain with Make 10s!

-Game introduction-
At regular intervals, boxes with numbers from 1 to 9 will fall from the top.
Select a number and put +, -, ×, or ÷ between the four numbers to make 10.
When the result of the calculation reaches 10, the selected box disappears and your score is added at the same time.
The more boxes you stack, the more numbers you can select, and the more calculation options you have.
The game is over when the boxes pile up too much and exceed the red line on the screen.
The interval between the boxes falling down becomes shorter and shorter.

-About the modes-
There are two modes: Normal Mode and Fantastic Mode.
In Normal Mode, one point is awarded each time a box is erased.
In Fantastic Mode, the player can play for a total of 1 point for each box erased.

-Future update plan-
We are planning to implement a global ranking system.
