Episode 1: the king's study with magic squares at 33:17 again at father "simplifies" magic squares
Episode 2: lunchbox action starts around 46:00 then again at the AHA moment
- at , there is no green circle on the 2nd row 3rd column square.
- at , I should have said: take any 3 or more of the numbers that add to 15, then the corresponding pieces combine into the 4x4 with the bite important because 7 and 8 don't work.
- at one of the pentominoes is a hexomino :
