Feed The Monster

Yesterday we played a came called Feed The Monster.    We took number cards and laid them face down.

 One of us would flip over a card.  We had to decide what number we would need to add to it to get a sum of 10.  Then, we would flip a card over.

If we made a match by making a sum of ten, then we took the two cards and fed them to the monster. 

If the numbers were not a match because they did NOT equal then, we would flip them back over.

Sorry, not a match there Trinity.
