Best tower defense games

I play a lot of online flash games. My favorite games are the tower defense games, mainly because they keep me interested for more than a few minutes. Here are my favorites from the ones I’ve played so far:

#1: Desktop Tower Defense 1.5 — By far and away the best tower defense game. Create your own maze with many towers. Towers are upgradeable through 5 levels. Three levels of difficulty plus many challenges. My favorite online game.

#2. Vector Tower defense — The selection of where to place the vectors, different mazes, and the variety of upgrades kept me interested for hours. The graphics and music fit the theme very well.

#3. Flash Element defense - One game I can easily say that the sequel is better than the first. The variety of enemies, towers, and upgrades were amazing. Also the ability to purchase elements back, move elements back, and other purchase-able upgrades made this game really enjoyable. It was a bit easy though.

#4. Bloons tower defense 2 - Pop the balloons and don’t let them escape. Pop the balloons using monkeys of different sorts. Many strategies you can form here by using tacs, cannon towers, dart towers, and more. There are certain ballons that are immune to certain attacks. Three difficulty levels are sure to challenge you for quite some time.

#5. Defender — Heros, upgradaeable unit-towers, and unlockable speciality towers put this game over the top. It takes a while to get used to the map grid though.

#6. Elite Forces Defense - A really good follow-the-path game. New paths for the creeps appear every so often so you have to pay attention. What really makes this game good is the numerous upgrade paths for towers and the hero.

#7. Anti-TD — Not so much great as it is for the novel idea. This is the opposite of tower defense. You must build a creep that can go through the defenses.

#8. Temple Guardian 2 — This plays more like an RTS than any other game. You have to collect numerous resource, build stuff like markets to increase your economy and then defend your temple.

#9. Turret Wars — Whats cool about this game is that you get to set up your own turrets and use natural obstructions to defend against enemies.

#10. Xeno Tactic - Alot like desktop tower defense but futuristic. Its not as robust as DTD, but the theme kept me entertained for a long time. A good variety of difficulties for maps too.
