Site for English Learning

I work for a few companies in Japan.
Yesterday my work finished at 23:30,
so I couldn't leave anything here.

One day I happened to find several interesting sites
for English Learning when I was working at one of my offices.

These sites must be interesting for Japanese learners, I think.
They are like games on the inter-net.

I am going to introduce one of them today.

Level 1 is boring, but some of them from Level 2 can be interesting.
Click several parts and enjoy them to be a better English speaker.
