Kingdom Rush

best game to play whenever you have a little time to spare (just switch to casual setting to avoid frustration).

This is a really good Tower Defense Game. I played first the flash version and now this PC port wich has all the DLCs of the Steam version. It has many "easter eggs" like the movie quotes that you can hear during the game wich makes this a very funny game to play. http://kingdomrushtd.wikia.com/wiki/Trivia There are some levels where the difficulty in normal is quite high, and you have to repeat the mission many times until you know how to deal with each wave. Highly recommended, great game, great music and very funny quotes.

Played this on Android before, and purchased from GOG to have the desktop version (Linux). Kingdom Rush is an excellent tower defense game with a fantasy twist and an entertaining campaign. It features several gameplay modes and will keep you entertained for hours. Some levels will get very challenging and may require a completely different plan to beat. Compared to the mobile version, this features 130 vs. 110 possible "stars" (which you get for completing levels in different modes). Maximum number per level is 5 so presumably there are four new stages. If you like TD and fantasy and a little humor, GET this, and play on your PC regardless of OS :)

I love Tower Defense games and this one seems too short if you ask me. It's a great game with alot of fun and challenges.

This is one of the best Tower Defence games of all time, but I must say it is a bit too challenging for me. It makes me feel like an amateur to play games on easy or casual ... but this is a game that requires a lot of time and skill to play beyond the first set of levels on normal or hard.
