Like a cross between Desktop Dungeons and Minesweeper.
I find this wildly addictive, even though the strategy has mostly reduced to a few rules now. Finally cleared all challenges 7 March 2026. Maybe I'll be able to put it down.
These kind of “fixed cost, fixed reward, hidden information” games really work for me. I wonder if they'd work for multiple players? Probably not, too much mental math, analysis paralysis. That might make them a good match for “grand strategy lite” though - almost what I wanted Dawnfolk to be.
