Fun.addictive flash/ios games?

I was wondering if anyone had a fun game that they play on their ipod or iphone that don't have very much publicity. I have been through several of the 'top 25 Ios games of all' lists, and none look very appealing.
I'm also looking for a good computer flash game, free of course.
For ideas of what I play:
Ios -
Temple run 1 and 2
Slenders - free
Extreme road trip 2
Curiosity - what's inside the cube
Simpsons all tapped out
Jetpack joyride
Songquiz
slamdunk king
flow free
Bejeweled

Flash:
Sas zombie assault
Bloons tower defense 1 to 5
Boxhead zombie wars
most games where you can upgrade things, but I just about exausted that search xD

Thanks for all your suggestions
I want to waste tons of time with these, so make sure they are extremely addictive!

Fastball 2 and 3, geodefense swarm, ninjump

  • Why is gadgets are so addictive? I had my iphone last year. It is my first time to own a smartphone. It is even fun to have when all my friends had it too. I realized I spent to much of my times on smartphone for social network and whatsapp. I can't control myself. I tried not to online but failed somehow.
  • What is the most realistic/addictive game for iPhone? I have an iPhone 4 and was just wondering what is the best game, any recommendations on what I should download… I don't want to pay loads either, free games would be even better, thanks.
  • What are some good, addictive iPhone games? School holidays are here and I have nothing to do! I need some good, addictive iPhone games, similar to Sunday lawn and Parking mania!
  • What are some fun iPhone games? Games that can kill time and boredom like when I don't want to pay attention in class lol, or when I'm standing in a long line. I've downloaded so many apps from the Top Games category on the app store but maybe there are games that are fun that's not on that list… So feel free to list them!
