TITLE: Tap Defense
SCORE: 3 / 5
An oldie but goodie, Tap Defense is pretty much Tower Defense for your iPhone. The strategy is simple: start each level with a finite amount of gold and use it to set up a variety of different weaponry and trap defenses to hold back the oncoming horde of monsters. For each monster killed, you earn more gold to buy additional defense or upgrade what you already have.
RECOMMENDATION: Challenging and addictive with a fairly easy leaning curve. Go for it.
