Japanese Puzzles are a kind of very addictive logic puzzles, in which you have to paint some fields following the numbers and you will see that the fields will form an image.

Reasons to like Logi puzzles:

Each puzzle has only one solution.
Puzzles are tested by a computer program designed by Urszula Marciniak, a mathematician and puzzle lover.
You can solve puzzles using only logical thinking - no guessing is needed.
The program is designed so that it uses only human kind of thinking. So even if a puzzle has only one solution, the program can reject it, because human will not be able to solve such puzzle without guessing and finding contradictions. This is what makes Logi puzzles enjoyable to solve.
Puzzles are created by professional graphic designers.
We have very high standards for graphics. We don't accept all images, they have to fulfill certain conditions, like no empty lines, clarity, and many other.
We set five difficulty levels.
The levels are set by a computer program, so they are always objective and the same.
No repeating puzzles.
The puzzles you see in this book are not published in any other non Polish language book. They were only published in our Polish monthly magazines available in Polish press stores or in online store at our website.
We publish puzzles since 2004 - we know well what puzzlers like.
If you have problems with solving a puzzle send it to us and we will show you a next step.
