It can be very frustrating searching for all possible solutions. But don't worry, I will give you some help.
The first thing you can do is to click symmetric patterns, because all solutions in my app are symmetric. If that doesn't help you, you can try the algorithm I explained on this page. If you still need help, you can view any solution you want on this page.
Just select the dimensions and the number of the solution you want to view.
It's definitely more fun finding solutions yourself, so please don't use this feature too often.
