As someone who played a lot of that game I can tell you it was not luck dependent at all. Entirely skill based, there was even a daily practice mode which would net you free plays. If the claw grabbed the piece it wouldn't drop it unless it got to the end. Most boards could easily be done with 5 plays.

Nintendo has kept scummy micro transactions to a minimum for as long as I can remember. Even Pokemon Picross had a maximum spend on micro transactions (after $40, any further premium currency was free)

The first and only time I tried it, 3 of my 5 free plays resulted in the claw dropping the better badges after picking them up, before reaching the end.
