Since the recent spike America taking interest in soccer..eehhh I mean football, my employer has put this stupid web filter up to keep us from watching the game on our computers because it seriously crippled our whole network. 1000 people trying to stream at the same time is no bueno for our system. We were warned several times before this stupid filter went up. Anyways one serious side effect is now I have no access to any awesome sites labeled: Game play and streaming, Streaming media, adult content, etc.. you get the point. I can't look up gaming news anymore or stupid youtube videos. I need help bypassing this web filter I'm sure there are a few pros out here.
I personally have to take the train to work about 40 min one way and I'd say get a handheld console, preferably 3DS, with some great games like Fire Emblem or Bravely Default. But since you asked Clash of Clans is a really good one its gotten a lot more clan war oriented and is very nice for long commutes. Radiant Defense is a cool tower defense type. Bloons TD Battles, another TD game except you play against another person. Bloons TD 5 if you want more variety and less competitive gameplay. Final Frontier is cool. FF3. Gran Theft Auto 3.
Now my personal favorites for android involve an app called ttorent. With this app you can download old school roms like FF7, Shining Force, any old game from ps1 and earlier, etc. You can play these rom files with emulator apps on the play store. Also you can play gameboy advanced games like pokemon and whatever. I don't really call it stealing since I've at one point owned these games and I still own most of them with the functioning consoles but whatevs.
I hope this helps your entertainment needs have fun.
