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/card

green goes first - and wins

green goes first - and loses





'pick it' involves placing counters in a ring (around any regular polygon)
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)
