There's an android app called MicRogue which is pretty much exactly that. The only RNG is in the setup of each level (which monsters are where to start). All attacks will always hit (with some predictable exceptions), and any hit will kill a monster... or the player. The fun of the game is in learning the rules that guide all the monsters movements, and predicting what will happen in a very chess-like manner.
Super deep in the coffee-break arena...
Think of a rouge with chess-like movement and you've got it. Not a lot of replayability but I dug it.

The old public build of Microgue plays like a cross between this and chess. Mouse-only controls, though. I sure wish I could find more games like it, as it's super short (3 floors, iirc) and the current commercial version is mobile-only (~~and isn't available for Android in the USA, apparently~~ EDIT: it actually is available, the website just links to the wrong address for some reason)...
That surprises me, I downloaded it on Android last year O_o
