The point of this thread isn't to post all hard machines, just any machines you like the easyier ones give every one a chance to play not just people with an encylopedia like knowledge of fruitys! Relax and have a bit of fun, don't take it so seriously lol.
That said if I get to post another I'll make it hard, since the other 2 were easy.
I don't take it seriously, but if you are going to step in and take someones turn at something, try and pick something on a similar level. Magz obviously seems to know his older machines, so don't pick a sub-5 year old Red Gaming machine which everyone knows

The easier ones don't give everyone a chance - you negated that point as yours was guessed by ONE person within a small time-frame. The older, more unusual machines give more people a chance to get involved as they can guess names, and stand a chance at flukeing a win.
