Can they all be solved?

The first release of Cogismo Logic Puzzles shipped with 229 level 1 to 4 puzzles.  All of these can be solved.  I know because I’ve solved all of them.  The first release of Cogismo shipped with 43 level 5 puzzles.  I have solved about one quarter of them.  As for the other three quarters,  there is scope for you to be the first in the world to solve these 😉
