The game is a Civilization, Age of Empires type of game and has a very involved tutorial which will really get you off to a great start. The stories that I have written about the game should teach you everything you need to know about getting started and what creatures you should create in order to protect your village . If you are more aggressive, there is a thorough description of each monster so that you will choose the best monsters to build before you take off to attack other villages.
The game has both defense and offense available so that you can play in the most aggressive style or be able to concentrate on building up your monster army to protect your lovely village. Much like Starcraft, you will have to face monsters that come over trying to zerg your village. Towers will assist you in keeping your buildings and creatures safe.
If you just enjoy the match three type of games more than the war games, I have created a few pages to help you enjoy Jungle Jewels and Bejeweled Blitz.
