Gem Invasion is a wonderful free online bejeweled game, and it has some different rules than those you may be familiar with. To begin with, the board is not filled with gems as you would find in other jewel games; the gems only cover a part of it and they are on the right side of the game. There is a reason for this. The gems will begin moving towards the left side of the game, and you have to stop them from reaching the red line bordering the board. If you the gems get to the red line then the game will come to an end. The trick here is to understand how to score well. You will get extra moves when you clear special gems. This slows down the movement of the gems; when you see the gems with a +1 on them, you should strive to match them more. If you get two combos, you will get a gem that has a bolt of lightning. This is a very special gem, since when you match it; it will remove all other gems of the same color. When you match 6 gems in one move, you will get a bomb, in the color of one of the groups that you matched. When you match a bomb, it will blow up 10 jewels. 9 in a 3x3 grid, and a single one, part of the gems that you have matched. In order to get to the next level, you need to meet the set score, which is at the bottom left hand corner. Use the meter on the left of the game to see how far you are from the given target. This is definitely a free online jewels game that will leave you bedazzled; get ready for the challenge.
