In all versions of Dimes Solitaire, the Foundations are started with a Ten (hence the name 'Dimes').
In this particular version, the Tens are placed on the Foundations as the game is being dealt.
Dimes is like Deuces with fewer columns. Inevitably this will make it harder to complete the game. As I've never completed Deuces successfully this strikes me as unnecessary!
At least the name makes sense.
