Mosaic is a puzzle game, with different playing modes and various skill levels. They all are united by common interface and idea - the goal is to match color blocks and remove them from the board. You could also play against the computer. The rules are as simple as they get. When you click on the block of square pieces of one color, they will disappear and the rest will drop down and shift left to fill the gap. Your aim is to remove as many of them as you can, better still - to clear them all. To make the life easy the removable blocks are highlighted when you move the mouse over them. When only single squares, with no matching neighbours are left on the field, the game is over. Both installer and uninstaller are included. To install Mosaic on your PC, just run the "mosaic.exe" program that you downloaded or obtained on a CD, and follow the instructions. The trial copy of the program will expire in 14 days. You can obtain a registration key any time during or after the trial period.
