There are two sections, one for compositions with normal force and one for compositions with promoted force, with 3 book prizes each.
To enter the competition in either section, a series-mover with not less than 45 moves is required.

All compositions should have a unique solution in "n-1" moves, and no solution in "n" moves.

Obviously, the two problems above (recently republished in feenschach 176!) would have not qualified for this tournament, both having less than 45 moves.
As an example, a problem that (barely!) meets the criteria for Section 1 is shown below:
