ATM there are 22 squares allocated. Each square would become worth 4 squares - so anyone who has bought 4 squares actually gets 16 squares.

That then leaves 12 squares left over. Every square purchase is allocated a random number from 1-22 and the first 12 numbers drawn out a hat get an additional square.
