I love this game. I've been playing conceptis puzzles for years. This is my second favorite (to cross a pix). I can't wait for a new one each week.

I love Conceptis puzzles, and this one is different enough to make me think. Really enjoy it!

Interesting puzzles, I especially like the really big boards. Well made, like all Conceptis games.

The "simplified" ruler update means rulers don't work at all. Please restore to earlier version! :(
