WFF 'N PROOF, the manufacturers of LinguiSHTIK, have produced many other games, all having the same parallel-universe board game feel, probably because most of them have educational value as their primary design goal. These games do a good job of challenging the player while being fun enough as a game to suck the player in. Equations: The Game of Creative Mathematics is similar to LinguiSHTIK in that players are setting constraints and trying to find a solution that meets them, but with numbers and mathematical operations instead of letters and words. WFF 'N PROOF cites research suggesting that students who sometimes get to play Equations in math class skip classes less often and are better at applying math concepts.
The even more interesting claim is that another game boosts I.Q. test scores:
The first studies published (in 1972) on the effects of resource allocation games involved I.Q. tests on groups of students playing WFF 'N PROOF: The Game of Modern Logic intensively for three weeks in summer school classes. The average increase in the non-verbal I.Q. scores was more than 20 points. Although researchers have questions about the sort of intelligence actually measured by such tests, it is clear that there was a dramatic improvement in the problem-solving skills utilized in such exercises.
Another game that seems really compelling to me is Queries 'N Theories: The Game of Science & Language

Like most of the WFF 'N PROOF games, Queries 'n Theories can be scaled down in complexity for the younger part of its age range (only sentences of length four for 12-year-olds) or scaled up to challenge more experienced players (sentences of length thirteen!). The most appealing part about this game, to my mind, is that it teaches scientific thinking and inductive reasoning.
There are two organizations that allow students to play some of these games against each other in a regular tournament: The Academic Games League of America and National Academic Games.
You can buy these games directly from Wff 'n Proof or you may be able to find them more cheaply (particularly The Game of Modern Logic
