Smileys aren’t just populating text messages, emails and forums anymore. They’ve gathered in Smiley Showdown 2 to create a game in which you destroy smileys through explosive chain reactions. Blow up your smiley and it will break into many tiny pieces that fly off and detonate the smileys they hit. Click at just the right time to create the longest chain reaction and destroy the most smileys. Blow up the indicated number of smileys to beat a level. As you go through the levels, you get to destroy the smileys with other weapons, such as cannons and lasers. When you see a special smiley, get a high score or create a long chain reaction, you earn an achievement.
