Pressure is one of the factors that make even the most mundane of games to become very exciting. Tempoma is a free online jewel game which gives you only 60 seconds to complete each level. This is obviously quite a lot of pressure, but you can alleviate it by concentrating on the tiles which have the symbol of a yellow clock; matching these will give an extra 5 seconds. Five seconds is not a lot for a novice, who may use it all trying to figure out where the next set is, but for an expert, it is quite a reprieve. You are supposed to swap adjacent gems to form a match of 3 or more identical gems. Click on the gem you want to move and then click on its intended destination; you may also drag the gem to the same position. Once you do so, the other gems will fall in to fill the empty space, and if they form another set, then you get what is known as a combo score. A combo multiplies your score, and this is the reason why most players of online jewel games strive to achieve this. When you get a set that has four or more gems, then you get a power gem out of the set. Speed is of the essence given that you only have a minute to complete the milestone required so you can proceed to the next level. This is a game that is suitable for advanced users, and those novices who never give up. Try and see how far up the levels you can go and then submit your highscore. This is an excellent way for you to spend an afternoon and be challenged as you try to better your score every time you play the game.
