With over 15 different levels to play, the game has great playability. Modern browsers can support this game easily and it runs smoothly. To complete a level, you must survive with at least one gem - this might sound easy but you must place towers carefully so that you can defeat the invading armies.
Certain towers can only be placed on certain types of land. Take this into consideration when placing your defenses. Moreover, different towers do different damage to enemy units. Orcs undead and demons are some of the enemies you will face.
When playing, you can also speed up the waves of enemies if you feel confident. Some players prefer to place their defenses early to prevent the enemies from ever getting close. Others prefer to have a mixed defense and a bulwark right at the end.
