Screen shot

You can place number on cells. And also can put or remove memo.

If your number obviously placed wrong position, it will be high-lighted.

How to play

1. Move the cursor into the cell you want to place the number or put/remove memo.
2. Type the number key 1, 2, 3, ..., 9 to place the number.
3. Or number key with Alt (or option if you use macOS) to put memo.
4. You can remove memo to type number key with Alt and Shift.
5. You can delete your placed number with Backspace key.

With Alt + Z, you can back the history. Alt + Shift + Z, you can go forward.

There is no EDIT and SAVE/LOAD. (I'm now working on these)
