A block puzzle is a frame of wooden blocks in different sizes, with two empty squares. Slide the blocks around until the big crate lines up with the gap at the bottom and comes out. On Survivor it has been built giant, with four or six players working one puzzle together.
Get the crate, X, out through the gap in the bottom of the frame. Press a block's letter to pick it up, then use the arrow keys to slide it. Escape puts it down. R reads the board row by row. H gives a hint in practice. Space starts a new game.
The block puzzle has shown up 3 times across 3 seasons, from All-Stars (season 8) in 2004 to Edge of Extinction (season 38) in 2019. Here is every one we could confirm.
