When you start the game, the number drop blocks

with numbers will drop from the top.

The blocks are gradually piled up.

Since the answer block flows from top to bottom on the left side,

Press the answer button when it becomes

the same as the number obtained by adding the bottom line.

If the answer is correct, the bottom line disappears.

The game is over when the blocks are piled up to the top.

Let's erase the numbers so that the game is not over

I will do it with such a rule
