In this game you start out by jotting down numbers 1 through 19 on a squared paper into 9 columns (and skip 10, there are no zeroes).
Then you start striking out numbers that are adjacent (diagonally doesn't count) and are the same numbers or have a sum of ten. Also, the struck out numbers don't count either, for example, if you have 4
5 6, then you can strike out 4 and 6 (their sum is 10).
If you have struck out all the pairs you can find, you write the left over numbers again and look for new pairs. You win if you've struck out all the numbers.
My question is - does this game have an actual name or is it "that numbers game that everyone played in high school"?
