It seems I was wrong in a review I recently left, for a game called "Make Everyone OK". That one WASN'T the first to get the idea for ternary lights out. Here we have one here, that did it in 2007, and got shamefully little recognition for it, while make everyone ok gets top page results on newgrounds. And this is clearly a superior game.
higgles, that's got to be one of the most ignorant comments in the history of comments. And I think you weren't even deliberately trying to be a troll. By the way, I can solve a Rubik's cube in about 30 seconds. Also, I can spell impossible. and Rubik's. So you rate down a puzzle game because it's too hard for you, even though you know it has a solution? "I'm stupid and angry so I'm going to give this game a score in proportion to my IQ! Grr! Grr!" Well sorry higgles, of we're rating this game in proportion to our IQs, I can't maintain the same ratio of stars to IQ points as you, I can only give it 5 stars total. Rate down a puzzle game if you think there's a problem with it and it doesn't HAVE a solution. Don't rate it down if you think it probably has a solution but you can't find it. Maybe unless it's maybe a nasty NP complete problem which just involves searching through a horrendous number of permutations, like this would be if the board were a little larger. But there are algorithms that you could figure out for solving this where you don't have to search through thousands of possibilities.
