A little rest can help you increase productivity when working or studying. You don't have to sit in front of a 'puter and a pile of papers all day and deny yourself any entertainment, fearing that you won't be able to adjust to the routine after the rest. While really stressed-out people might prefer the simplicity of a 3D-shooter to relieve them of their tension, others will enjoy playing a simple puzzle game - 4Free.
     4Free is a game with very simple rules and an easily-grasped goal: you play against the computer or another person, in turn trying to place balls of one color in a row. The one who manages to build a row of four balls is the winner. The game can be played in ten different levels of difficulty and you can choose who plays first - you or your opponent.
     The game engine is open source: if you're a programmer, you might want to build your own engine for the existing interface. The game can be played full-screen with 640x480 resolution only. Download this free game today and have a bit of rest!
