„Only” logic – or not?

Abstract

In this paper I intend to show some playful logical puzzles which we have used for several years in the teaching of primary school teachers and pre-school teachers in their mathematical classes. Each of the games presented is basically a logical game (some of them are based on the well-known Sudoku game). However, for solving some of the exercises one needs not only logical thinking but for example the use of the four basic operations. In the case of some other puzzles the correct way of spatial orientation is also necessary for solving the logical problem. In some other cases we meet the problem of covering spaces and some basic properties of graphs.
