Uno Player Machine!!!!!!  

Awesome!!

Great machine! The K'nex mechanisms were pretty neat and the trick at 0:15 was cool too :)

this is really cool! that car that rolls up the track at the beginning was really smooth!

Ooh, nice!

OMG that was such a cool machine! You really had some amazing ideas! I hope you do well

Okay now that’s clever

But it's not 1 meter square setup How it's still valid??
