Puzzle Machine is a collection of 4 different logic games with thousands of predefined puzzles in 10 levels of difficulty each. Play without time limit and solve 3 randomly selected puzzles in a row to unlock the next level of difficulty. Play more and more puzzles at your preferred level of difficulty. Who does what? There are always 6 people and you have to find out what they eat, what hobbies they have and so on. There are always 6 possible answers but each answer only fits one person! For example, if you know that Ben rides a motorcycle, none of the other 5 people can also ride a motorcycle. This allows you to clearly match each person with the statements you see. You can click on the statements to highlight or hide them. Grid of Things Items from different categories and in different colors must be placed on a grid. The rows and columns show you how many items of a certain color, from a certain category or with a certain name there are. This is not a Sudoku: completely identical objects may appear several times in a row or column. Knight, Pirate and Spy Each person in this game is either a knight, a pirate or a spy. A knight always tells the truth, a pirate always lies and a spy can decide for himself whether he wants to tell the truth or lie. Each person makes a statement about themselves or the other persons. From this you must recognize who is a knight, who is a pirate and who is a spy. It is important to know that there can never be more than one spy. But there can be several pirates and knights. Zoo Director As zoo director, you have to find out how many animals there are of each species and color. There are always between 1 and 9 animals. With the statements you see, you should be able to determine the exact quantity. Please note that animals can belong to several groups at the same time (e.g. mammals and carnivores).
