Spiralling Decimals

Today my maths group did spiral decimals. It was a game. For me I had a little strategy witch was start with the smaller numbers then go to the big ones. It doesn't matter who goes first in the game.The number you pick first doesn't really matter. You need a buddy for this game First one to get three in a row with no one blocking them wins. You need to of the sheets and play one round on each sheet.
