This is not a "mate in X moves" type of puzzles game; it's the type of "mathematical chess" puzzle (for example, placing pieces on the board such that they don't attack each other, or such that every square is attacked, etc).
The puzzles are available in multiple difficulties / board sizes, to give the player the chance to gradually familiarize themselves with the problem. For example, the "eight queen" problem (place eight queens on the board in such a way that they don't attack each other) has an easy version (4 queens on a 4x4 board), a medium version (6 queens on a 6x6 board), and the hard version (8 queens on an 8x8 board).
More puzzles will be added soon, as the app will be updated.
