+Strip a chessboard to one row of eight squares and you'd think the game collapses — instead the puzzles get harder to see, because the spatial intuition that helps in 2D is gone. A small browser toy that takes about thirty seconds to learn and longer than expected to get good at. Free, no signup, no ads.
