Machine hints are directly available after you have started a machine. Please note that a machine must be running to access its hints, and you are only able to access three hints in a 24 hour period. This means that if you access a hint at 8AM, and then a second at 10AM, and a third at Noon, you will be able to access one more hint at 8AM the next day, another hint at 10AM, and a sixth hint at Noon.

Note: Using hints decreases the total point value of the machine. However, hints can also be used for free when you are able to submit all flags for the machine.
