I loved playing flash games on Kongregate, Ninjakiwi and Freewebarcade about 4ish years ago. I still do, but that was the peak time for me. Notable ones which I can think of include:
- Epic war series
- Swords and Sandals series
- Bloons Tower Defence series
- Age of War
- Warlords
- Empire of the Galaldur
- Gemcraft series
There are definitely more, but these are ones which I can recall now.
If anyone wants to download these flash games, to have them permanently as a SWF movie (flash movie):
1. Go on freewebarcade.com
2. Go on the game you want to play
3. Right click, view page source
4. Ctrl F, ".swf"
5. The link that has .swf at the end - click and then it will download the file
6. This should work for MOST games on this website - it is a cool thing that I do for games that I liked and downloaded them permanently.
7. Enjoy!
