I noticed a student spamming solution in Algebra Cyphers, so I changed the solution verification.  Before it only ejected incorrect tiles.  But this made it so someone could put in tiles until they had the solution.  For now it ejects all the tiles in the solution row if any are wrong.  I would like to have some better sort of feedback, but I don't know how to do that yet.

I need to figure something out for Hexagon Functions, because that has a similar issue.  I was thinking about a temporary slowing during each error or having a danger element like Venn Diagrams has (with a reroll of the random elements).  Maybe there is another idea that would be better.
