My dad due to hand surgery doesn’t have the best of fine motor control. The https://tbgd.blog/2019/01/13/turing-tumble/ review stated:
Handling the marbles is not the easiest, especially for someone with ‘regular sized’ fingers. I imagine it would be much easier done for children, but it feels like the tray could have been differently designed to make the marbles easier to retrieve and load, or maybe a tool provided (scoop, tweezers ,etc) to grab them with.
Does anyone have any suggestions?
