Thanks for your time.
In the game millionaire, in the part see attempts does not allow me to erase attempts of the participants. I am in version 3.4+ of Moodle and 2017081401 of the game module. I had the opportunity to review in moodle 2.7.3, version 2014071317 of the game module and the same thing happens. There is some way to solve this problem.
Best regards.
Neider.
