winning ways

(supplementing your income...)

two games - both with a definite winning strategy, based on types of symmetry

'cover it' involves covering two adjacent squares


you could use dominoes
red Cuisenaire rods
sticks (or cut up bits of paper)







green goes first - and wins

green goes first - and loses





'pick it' involves placing counters in a ring (around any regular polygon) and at each turn a player chooses to pick either one or two adjacent counters
if they choose two counters then they must have been joined by a line in the initial configuration (i.e. be neighbours)
