Fun flash games

I think this is my favorite:

I often play these little games/minigames for inspiration on projects.

What game gets your vote? It has to be smallish and made in flash.

Fantastic Contraption and Winterbells.

Definitely Heli Attack 2 and 3, they're on www.mousebreaker .com and I love playing them when I'm trying to pass the time.

Fantastic Contraption for me too.

Magic Pen/Incredibots gets my vote for physics games... Magic pen was way to easy though.

99 Bricks is a bit of fun.

I should probably mention that whilst it *looks* like Tetris, it really has more in common with Tower Of Goo.

You'll see. :o)

Tanks - very fun :)

Fantastic Contraption of course, but:
Shift is pretty cool.
Spin the Black Circle is very slick too.
