Having played this a number of times, I am going to have to argue that this uses deduction. You have a chart that shows all possible directions your pieces can move. When I try to move a piece, my opponent tells me yes or no. This allows me to eliminate some of the pieces that it could possibly be. Eventually, I have elliminated all but one possibility and have deduced which piece it must be. You can also used deduction to narrow down which piece is which because there are 5 that can move straight forward, 5 that can move diagonally forward, and 2 that can do both. Once I have identified 7 that can move straight forward, I can deduce that the remaining 5 must move diagonally forward.

This is a fabulous game--no matter which type of logic it falls under. And I must admit--I consider the line between what is inductive and what is deductive to be fuzzy sometimes. Often both are at work.

Looks interesting! I have never seen this one before but I would like to try it.

Valerie - you are of course right. Although finding out general rules, it is a deduction game, because you know the options.
The feeling is induction, the game is deductive

My fault...

Again, while this is considered a classic "induction" game, a good player will use both forms of logic.

Using induction, you try to discover all possible rules that could be correct. Using deduction, you test those "hypotheses" and eliminate them. You can often be efficient and eliminate several hypotheses at once with a good test.

Of course, many players do only use inductive logic. They think of one possible rule and get stuck on that option until they learn it is wrong. Then they use inductive reasoning to think of another one.

True, Val, but I think you could say that about any game based on inductive reasoning. I'd say that both Eleusis and Zendo qualify as pure induction games.

Of course. But this is exactly why some students struggle when trying to understand the difference between inductive and deductive reasoning. The fact that we often follow our induction with deduction makes it harder for students to distinguish the two. On the other hand, once students understand that it is okay to be confused because they overlap--and that their confusion is a sign that they are finally grasping the deeper concepts...well, they just throw their hands up in the air at that point.

Heh - Looks like you added your Zendo while I was typing mine. Well, it's twice as good as most other induction games, so...
