Riga Add-a-Piece competition 2022

The program of Riga ECSC 2022 ( includes a new kind of Solving-Composing event, named Add-a-Piece competition. It was aimed to entertain the participants, and described on the official website, with a set of 6 examples offered for participates to solve and comment.
Several registered participants have already commented the tasks and kindly informed me about the time they used for solving. Surprisingly, the reported times varied from 30 minutes (with 1 mistake) to 3 hours.
I would be glad if some of the MPF members try their hands on it and send me a feedback to, especially about the time needed for solving. To the already written details I should add that no retro trick were intended.

Interesting! (But not THAT different from classic "reconstruction" challenges.)
Is it allowed to computer-check the correctness of the own "solutions"?
(As usual, this takes me only a few seconds to solve - for the #2!! -,
but I don't know yet if I'm correct.)

No, computer is excluded!
I want to know the real time needed for solving without computer in Riga.
Thanks to Wouter van Rijn, I already got to know there was an unintended solution in No.4!
As about comparison with reconstruction, you will see the differences when you solve them.
