In Nivos there are 25 building blocks of different shape and colour. Each turn you place one block with simple rules: when played on the starting grid: don't put it on an empty space and don't touch a block of the same colour.

For every infraction you get a wooden cylinder. Every cylinder being a little bigger than the one before. You stack them on top of each other.

Make sure that by the end of the game you have the smallest cylinder stack.
