The word catalyst must be a familiar term from your grade school and high school chemistry. A catalyst is a substance that hastens chemical reaction. By merely hearing that definition, you already probably have a clue on what is in stored for you in the Catalyst game. In the catalyst game you will be taking charge of some chemical reaction. You will work just like the way a catalyst works in science. You must be able to hasten the chemical; reactions to be able to eliminate them. Your goal is to move the catalyst to the molecules that have the same color. You can move the catalyst by pressing on the up, down, left and right arrow keys. Once the catalyst is already in the molecules column, you can already press the space bar in your keyboard to eliminate the molecules. If the molecules have different colors, the catalyst will simply absorb them. You will also be encountering special molecules along your way in the catalyst game. These molecules will make your life easier in the catalyst game. Some of these special molecules can clear all the molecules behind them. The special molecules can also reshuffle the molecules or put a halt in the manufacturing of molecules for a few seconds. There is also a meter that will tell you how far more you must work as a catalyst. Be involved in you chemistry subject and get a chance to appreciate the world of atoms, molecules and catalysts in the Catalyst game.
