The term "solitaire" is also used for single-player games of concentration and skill using a set layout of tiles, pegs or stones rather than cards.

This puzzle game will give you a unique opportunity to improve your skills of solving problems and puzzles, train your brain, memory and spatial imagination.

The rules are very simple, and remind the classic Klondike Solitaire:

- There are 12 slots in the playing area, each of which can hold up to 4 balls (up to 5 at higher levels). Initially, the balls are arranged randomly, and your task is to sort them out so that only balls of the same color are in the same slot (thus forming a line of balls of the same color – a color line).

Balls can only be moved according to the following rules:
- To move a ball from one slot to another, you need to click on the desired ball, and then click on the slot where you want to move the ball.
- The ball must be put in an empty slot or placed over a ball of the same color (provided that there is a free space in the lot)

If in the process of moving the balls the built-in analyzer detects that the player has got to an impasse, the system will notify you of it and offer to roll back to the last solvable state.

We have streamlined the interface, leaving only basic features to make this mini-game simple and easy; however, this mini-game will carry you away, and bring you many pleasant moments when solving this sophisticated puzzle. You can pick various textures for the balls, which will make the game more enjoyable. We have also paid attention to the soundtrack and your tactile senses during the gameplay. Now you can truly enjoy the gameplay!

Brain Marbles puzzle is an exciting game that everyone can enjoy, from simple to super complex levels limited in time and number of moves.
