Corners Up Game by Fat Brain Toys - 8yrs+Are you clever enough to collect the most corners? Each player gets 20 game pieces of one colour. On each turn, players have to place one of their pieces adjacent to or on top of the other pieces within a 4x4 grid, building a pyramid as they go. When a 2x2 square is completed, whoever has the most pieces within that 2x2 square gets to place one of their pieces on top of those four. Can you trick everyone else into providing you with the best moves?
