Given a search space S={1,2,...,n}, an unknown element x^*@?S and fixed integers @?=1 and q=1, a q+1-ary @?-restricted query is of the following form: which one of the set {A"0,A"1,...,A"q} is the x^* in?, where (A"0,A"1,...,A"q) is a partition of S and |A"i|@?@? for i=1,2,...,q. The problem of finding x^* from S with q+1-ary size-restricted queries is called as a q+1-ary search game with small sets. In this paper, we consider sequential algorithms for the above problem, and establish the minimum number of average-case sequential queries when x^* satisfies the uniform distribution on S.
