Incomprehensible interface errative puzzle game. No instructions!

This product includes 3 different puzzles.

Native Windows Forms interface.

The goal of each of these errative puzzle games is to set all the flags and then perform the final control activation, typically a scrollbar movement.

All the flags are hinted in a message box which is shown by pressing a certain button in a previously unknown place.

Every game has a way to close itself unexpectedly - this is a gameover and you have to restart it manually.

Some controls reset your progress, but sometimes it is necessary to advance.

In the end, the game also closes itself. There is only one way to finish each puzzle.
