Category Adventure at this moment contain 5 adventure games. Each game has couple of levels, usually 10 or more. Each adventure has own story and there are level dependencies which means that you need to solve the game level by level. Once you have first level you can go to second one. In this category you can find the mix of riddles from other categories.
Orbis pictus
Easy category if we are talking about the rules. In each riddle you will see the picture and you have to answer what you see.
It is the known person ? Try his name. City ? Which one ? And what about animals. space objects, ..
It is quite popular category. Of course there are also some complicated object which you have not know at the first try. then you have to investigate and start searching. Internet is allowed and google is mighty wizard :)
Logic
Logical task. There you can find mathematic riddles which have chance to see them in the schools. Mostly they are extended with some trick. More riddles you can find in this category there is better chance that some of the riddles you have not ever seen.
Mathematic is important but mostly you will need to use logic. I have tried to do my best to select only the riddles which have only one unique answer.
You can find here several number or letter sequences, some of them you will solve it using math, some of them by logic or by using little bit of associaction.
Associations
Name of the category is Association and is quite clear. This is new category I have created just for test if the people will like it or not. At this moment some people love this category and others hate it, still it is popular for most of the solvers. Associations are individual so there is no only one correct answer and you have to find the chosen one (expected). You will have a chance to find many hints to help you find the correct answer.
How it works ? I will give you the word FIRE. Association for this word can be WATER. Sometimes you need to find opposite word, sometimes the symbol, meaning or what two words can show together. One more example: Dartagnan .. association can be musketeer , Dumas, book, ..
Mix
In the Mix category you can find riddles for which I didnt had time to put them into correct section or simply they do not belong to any of existing category. Because all of them are different, it is hard to explain how to proceed. Unfortunately there are no rules showing how to solve this riddles and you have to find the solution by your own.
Crypto
Crypto is from greek word Kryptos which means hidden, secret. Our category Crypto is directly related with cryptography. Cryptography in our category is also close related with encryption. Easy explanation is: convertion of readable text into nonsense. There are a lot of methods how to encrypt/decrypt the messages or easily can be invented new method. Or just to modify existing one.
For all of you which do not know how to start and what is cryptography about, at the begining you can start to read someting about ASCII. Or some history about Cryptography.
Stegano
Stenography is older sister of cryptography which means hiding messages as is. There can be found methods like invisible ink.
In the modern age secret messages can be hidden in files containing sounds or pictures. Messages can be hidden using several methods and on several places.
Zebra
Zebra category is based only on pure logic. In the text you can find everything what you will need for the solution. Some of the riddles can be solved right from the head and for others you will need to use at least pen and paper. Be sure that you really do not need anything else then logic.
