How would you perform the "Calc Magic" routine?

Please be sure to check the video of the comment.
There is a commentary on [ Developer Website ]


【What kind of magic?】
Computing some numbers randomly pushed by multiple parties will match the numbers predicted in advance!


【How difficult is it? 】
I made it so easy that everyone can do it. Please try using it by all means.


【Difference between free and charged app version】
The free version is for confirming whether there is no problem using it actually and whether this application is the application you thought.

Therefore, there is a "free version" logo.If you really want performance, please purchase a charged version.
