This challenge shows potential but has significant limitations. A more comprehensive and nuanced challenge about snooker breaks would greatly benefit the platform. Developing a replacement that captures the full complexity of snooker rules would be a valuable contribution. Should I have a go at creating a new challenge, aimed at replacing this one, or can this existing one be effectively resurrected and improved?

Player class should be preloaded.

The rules have to be explained in the description - the user should not have to look up other resource just to understand what he's supposed to do.

my solution should be invalid if it only passes sometimes

Would be helpful to state that the break is being made from a table in it's initial state (i.e. all balls are present on the table).

For example, the test says that a break of just the pink ball is invalid, but that would be a valid break if there was only two balls left on the table.
