Elf Defence

Elf Defence is a classic tower defense game in which players must repel wave after wave of invaders. The invaders in question are actually little yellow balls, which move in laps around the playing area. Installing guards at strategic locations around the board allows those little yellow blogs to be defeated. At the end of each round, there’s a boss character that must be defeated if the player is to progress. Towers can be upgraded by merging them. This isn’t straight addition, however; merge two towers of the same level to form a single one of the next. So, two twos make a three, and two threes make a four. This is a great game for tower defense fans!
