Here are its permutations (e. g. using Algorithm::Permute; cf. also an explanation of permutations in Croatian, Faculty of Medicine, University of Zagreb):
ad eum est concursum ad est eum concursum est ad eum concursum ad concursum eum est ad concursum est eum ad est concursum eum est ad concursum eum concursum ad eum est concursum ad est eum concursum est ad eum est concursum ad eum eum ad concursum est eum ad est concursum eum est ad concursum est eum ad concursum eum concursum ad est eum concursum est ad eum est concursum ad est eum concursum ad concursum eum ad est concursum eum est ad concursum est eum ad est concursum eum ad
The game throws permutations at you — you have to decide (that is, put each into a basket) whether permutations are: a) impossible, that is meaningless; b) possible, but meaning something else; c) acceptable (but rare); d) probable.
Computer can play against you.

Inspired by predictive text entry. Use frequency data from the text we're reading to offer possibilities among which the player has to choose. Multiple grammatically correct, and linguistically possible, answers are offered, but Pythia shows no mercy, and accepts only what the author has actually written.
Meanings could be introduced as hints (then, of course, you lose some points).
