4 In A Row is one of Monty's Games for Windows and is a simple but very addictive strategy-logic game with beautiful Ray-traced graphics. Prevent the game field from filling up with blocks by moving blocks so they form lines of 4 or more of the same color. THERE MUST BE A PATH TO THE DESTINATION ! If there is a path to the destination, the chosen block is moved along that path to the destination and any new lines formed are removed and you earn points.After every move you make, the computer adds blocks to the playing field. The number of blocks added depends on the difficulty level choosen. When you remove 7 or more blocks at the same time you earn bombs. Use the bombs to remove blocks. This is especially useful when the game field starts filling up.You earn points for removing blocks, the more blocks you remove at one time the more points you earn. It's easy to remove 7 blocks at once. It is possible to remove 22 blocks at one time but I have never done it - it's worth a ton of points.
