Description
Select two numbers on the grid and erase all the numbers of the theme!
The number of squares and the number of the theme are displayed.
Choose two numbers in the squares to make up the theme number.
If it is correct, the number of the subject disappears.
If you can't make the number of the theme, it's game over.
If you erase all the numbers of the theme, the stage is cleared.
It is a slightly difficult addition puzzle game.
