The Isis Adventure

I just bought an Isis, and cracked the clues... So,

1. I can't be sure of how many bearings are inside, is there any way to know that accurately?

2. To release the third, I have to have the correct combination? Is there any clue to that combination?

3. Finally, if a "brute force" method is required, Do I have to press the plunger after each comination, or will it just release?

Any help would be appreciated

Firstly, welcome to the forum, and well done on cracking the clues
Unfortunately due to the information your asking for your very unlikely to get the answers you expect or want.

1. Yes, there is a way to know accurately... you open it up On the basis your not at that stage yet, if you've solved the clues that should give you a good idea

2. Again, that's not the kind of question thats gonna get an answer to outside the 5% club, and again if you've solved the clues they should help.

3. This kinda relates to the previous question. In general though if you have an idea then give it a go, if it's not working then try something else.

The thing to remember is that all you need are the 10 clues that came with the Isis and the 11th clue which is scattered all over this forum.
Read the forum if you get really stuck, there's loads of information here

Good luck
