This is part way through a game (I didn't lay it out the way the Rulebook had shown).

I'm likin' it (what else is new? 🙂), but I'm a bit unsure on a couple of points in the Rules. I'll Post a question on BGG. The Designer (John Grills) has been quite diligent answering the several questions already there (I knew the answers before I read 'em). My question hasn't been asked, yet. Nice and small (the box is only 2.5625" (6.5cm) long). Z, I think you could play it on a "train tray". It's a light, quick game made for just 1-Player.
I have a couple of other Solo games by John - The Great Escape & The Rat's Lair (both also small).
