Can Check box be required in Sales Force

Yesterday i was working on something and to full fill a requirement i tried to make a check box required. Without looking at the feasibility i start going ahead and found this can't be done.

A field can be made Required at the time of creation or on the page layout and i tried both but no luck.

Then i tried with the help of Validation rule and created a rule like:

IF( test__c , FALSE, TRUE)

Although it worked fine but i rechecked it as being a tester and then i found it is not feasible at all.

How?

Let suppose you want it required but what if user don't want it to be checked in that case rule will not fire and that is the reason why Sales Force haven't provide facility to make a check box required.
