thanks,mate. I think the spring on the stepper (NOT the 0-9 unit) could have one more turn put on it, as it wants to reset but sometimes stops a few notches short of 're-set'. I set the tension before the game was ready to start, and didn't want to do it too hard, and make more pressure for the 'adding' coil........ I probably won't get a chance to do much more on this for a couple of weeks as my wife and I are going to Rainbow Bay for 2 weeks holiday. Thanks for your help. ... I look forward to what you have to say about the 0-9 unit on my post for 'Kings and Queens'. Cheers, Mark
