Squayles
This is a game for two players. You will need 31 sticks (match sticks are about the right size, but craft sticks are better).
Do NOT use live matches. Get a grown-up to prepare some dead matches for you. .
Lay out the sticks to make three rows of four squares.
Each player takes turns at removing any stick along with all the others that touch it. For example, if you chose the blue stick below, then the six red sticks must be taken too.
