Again, awesome video!!! Thank you very much! Just a few comments: 1) You can flip the card of the slot blocked by a bug to mark it more clearly. 2) I would use NOT in basic games, then add OR, AND and XOR, then NOR, NAND, XNOR, and finally ADD and SUB. 3) I love the explanation of the "negated" operations (NOR, NAND, XNOR). They are the same as they non-negated counterparts + a NOT. 4) Using SUB with negative results is VERY tricky but you explained just perfectly! Great job! :)
