Feb 27, 2016 at 3:59 comment added Mark S. When 0 is not in the validmove array, this game is called a "finite subtraction game" or a "subtraction game with a finite subtraction set". The nimber sequence will not always be purely periodic. For example, if the validmove array is $\{3,4,6,10\}$, the nimber sequence (with commas and braces omitted since the nimbers are all less than $10$) is $00011122203314\overline{00201312}$. These types of games are discussed in many combinatorial game theory texts, including the undergraduate textbook "Lessons in Play: An Introduction to Combinatorial Game Theory" where the above example comes from.
