GAMEPLAY

We present the game items below. It is advisable to learn the item characteristics as they have a major impact on playing.

GAME ELEMENTS
	Generator - with regular intervals it generates balls.
	Ordinary rotator - clicking the rotator makes it turn; with the left mouse button, it turns anticlockwise; with the right mouse button, it turns clockwise.
	Gravitational ordinary rotator - a ball which falls on the rotator overbalances it on the side it has fallen. If two balls fall on it, the rotator remains still. Besides, like in case of an ordinary rotator clicking the rotator with the left mouse button, turns it anticlockwise and with the right mouse button, turns it clockwise.
	Combined gravitational rotator - it operates like the one above with a slight difference - other rotators can be attached to it. If one of them moves, all the attached ones move with it.
	Delayed combined gravitational rotator - it operates like the one above with the exception that the attached ones move with a little delay.
	Gravitational rotator with changing colors - it operates like an ordinary gravitational rotator, but the turn makes it change the color into another one.
	Gravitational rotator with changing the color - it operates like the previous one, but the color changes in a strictly defined way.
	Blocker - the field with a blocker is inaccessible to balls. Blockers can occupy several fields horizontally and horizontally.

GAME RULES

The general game rule is manipulating the rotators in order to combine four balls into a square. It makes them disappear from the board and scores four points.
NOTE: It is possible to combine not only 4 balls, but also 6 at a time. At the level with a limited number of balls, such situations should be avoided, as the it could be impossible to finish level then and player will be forced to use RESTART button.

Playing at different levels can be based on three rules:

1. Time game - There is a defined period of time, which is presented under the level number as a bar which decreases in time. A player is supposed to remove balls as they are generated by generators. Switching to another level takes place when the time for a particular level passes. When a ball is blocked by another one on the generator field, and another one is generated, a player loses one life. When a player loses their last life, they lose the game.

2. Logical game - A number of balls is generated and a player is supposed to remove all of them from the board. There are no generators. Time does not matter.

3. Logical time game - A number of balls is generated and a player is supposed to remove them all from the board within a defined period of tome. When the time is over, a player loses one of their lives. When a player loses their last life, they lose the game.
