Some fun online games include “The Great Siege” and “Bloons Tower Defense 4.” Both of these games are available to play for free on arcade websites such as Kongregate.
In “The Great Siege,” players have to fight the Dark Lord who has sent his minions to enslave humanity. To avoid his wrath, the player has to build up the city and defend it from waves of minions to keep it from falling. In between battles, she can choose new buildings to construct to aid this cause in different ways. During battle, she defends the town, using the computer mouse to fling rocks at advancing enemies. At the end of the battle, the player gets a score based on the number of enemies killed, how long it took, the amount of damage that the barricade took and the type of victory that she achieved.
“Bloons Tower Defense 4” is a tower defense game in which players build tack-shooting towers to keep Bloons from successfully navigating to the end of the stage. Gamers have a certain number of lives, and they lose one life for every Bloon that is successful in reaching the end. Once the player runs out of lives, the game is over. Players receive money for each Bloon they pop and can use the money to buy new towers or upgrade existing towers.
