We hope that you are up for more online tower defense games, since it is exactly such a game that we are now offering you all in the Armor Games category, where we are sure that you have enjoyed all the games we added in it today, and GemCraft is going to be no different, since we enjoyed it as well, and when we like a game, chances of it becoming popular on our website are very high. It is a classic game, with rudimentary graphics, but that does not take anything away from the fun you can have with it, trust us. We will offer you some information about how it works right here and now, so make sure that you pay attention! Well, you are going to use the mouse. Monsters are going to attack your base, which is why you are going to use the mouse to place gems along the towers, gems which have the ability of fending off these monsters. When you are successful in defending your kingdom, you will get money in return, which you use to either upgrade your defenses, or get new gems to place, because you need to get ready for the next time that you are going to be attacked. Give the game a go right now, only on our website, and have fun!
