Casual Jewels is not an easy free online jewel game, even though the name might suggest that it is. This is a challenging gems game, in which you match 3 or more gems in order to remove them from the game, and in the process, remove all the metal, wood and cement tiles in the background. When you remove five or more gems you get a special gem of the same kind. The first power-up that you get will give you a rocket. When matched with similar gems, it will remove four extra gems, one on each side. When you create another match of five gems, of the same kind as the one you had created before, you get a bomb. This will remove 12 tiles in the shape of a rhombus when it is matched with others of its kind. If you get another set of 5, then you will get a powerful bomb, which will remove 24 tiles. This will need you to match 6 similar gems. When you match 7 gems, you get a cracker which will remove gems in a 3X3 grid. A lightning gem is given when you have made 6 power-ups, and it will remove all gems of the same kind. You do not have to match it when it is given; you only need to double click it to remove all gems of its kind. With this small legend, you can now play the game and see how well you can perform. You need to be a good strategist if you want to create these power-ups. They need you to have a quick eye and fast finger, and also a very sharp mind. Playing gems games can help you improve your ability to solve problems very fast even in real life, something that will prove useful in the future.
