I think you are big lover of this game...I like it also. When I fill boar from the same work I use to play it for some time and refresh my mood and go for work again. I like it because it has a place to think deeply with fast timing and I love to think deeply.
You can learn it through help section of this game. Its a very good game for mind and it increases concentration.
I already stopped playing the game. It gets bored after a while and have not touched it since. One thing which kills my interest is that the statistic that shows the top score can actually be edited.
I also like to play minesweeper, but still in beginner level, my score is is 19 sec on the beginner level
i find mindsweeper a bit pointless, usually try my hand at something a bit more advanced like an online mmorpg or something similar lol (although never a fan of WoW)
I generally play Minesweeper when I am in office and free from work. My score is 37 sec for intermediate level....
