At the beginning of each game there are 3 different colors of blocks for you to crash. To crash blocks you must find groups of similar colored blocks that are all in contact with each other. The smallest group of blocks that can be crashed is 3 but removing larger groups will get you many more points because the more blocks you clear at once the more points you get! To reach the next level you must clear the number of blocks shown in the remaining field and with each passing level the number you must clear increases. Depending on the difficulty the will be 3, 4 or even 5 different colored blocks to crash.
