Power Grid

I'm stuck on the Power Grid puzzle. Even though I don't need to complete it to finish the game, can someone help me solve it ?

    I didn't read the instructions on that one closely enough the first time around - you have to use all the available power outlets (so there'll be a line coming out of each circle). Does that help at all?
  • The instructions make no sense to me at all. I feel like an idiot. I wanna solve it, but the hints are way too vague, as well.

    You have to use all the available power outlets, and a generator's power is halved between its outlets, so essentially the numbers are like this:


    Then you just have to join them up so that the sum of the numbers attached to each appliance matches the number shown on that appliance.

    If you need help getting the computer hooked up to start with, check this screenshot.
    5 + 15 + 15 + 5 + 5 = 45

    And here's what the solution looks like.
  • There are multiple solutions, I've beated the game twice and, although I'm not sure if I got the same solution both times, I'm sure I didn't have puzzlebox's solution

    Clearly I should have said "Here's what a solution looks like"! ;)

    I wonder how many there are?
  • If you count every solution with a different set of lines separately, then there are 856 solutions.

    This includes many trivial variations though; for example, you can always swap each pair of connections coming from a single generator (and if they are connected to different machines, this gives a different solution), and similarly the four connections to the two 10 Watt generators can be freely permuted, et cetera.

    If you only consider solutions different if some machines draw different amounts of power from different sources, then there are only 8 solutions:
    1. 15=15; 15+25=40; 5+25=30; 5+5+5+15+15=45.
    2. 15=15; 15+25=40; 5+5+5+15=30; 5+15+25=45.
    3. 5+5+5=15; 15+25=40; 5+25=30; 15+15+15=45.
    4. 15=15; 15+25=40; 15+15=30; 5+5+5+5+25=45.
    5. 15=15; 5+5+15+15=40; 5+25=30; 5+15+25=45.
    6. 5+5+5=15; 15+25=40; 15+15=30; 5+15+25=45.
    7. 15=15; 5+5+5+25=40; 15+15=30; 5+15+25=45.
    8. 15=15; 5+5+5+25=40; 5+25=30; 15+15+15=45.
