All depends on if i feel like playing, i've had a few times where i try to play a game, and im just not into it and i'll just switch it off mid game
Its very sporadic with me.. sometimes i'll play at least one machine every day, or there'll be times where i'll go a whole week or so without even turning a game on!
But generally i'll try to have a game or two on at least one of my machines each day. Sometimes i'll turn them all on and play one game on each machine.
Plus working from home now and having the bulk of my machines in my workspace means i can have a game anytime i feel like it
Also i have one game set up im my dining room (soon to be two) which means i dont have to go down to the shed to play pins.. only trouble with that though is i sometimes have to wait til everyone else is out of the house
