A paper is folded into a few sections depending on how many ppl are playing. The first person draws on the first section and leaves a hint for the second person in the next section. The hint should be a continuation of the work in section 1. The second person will draw in section 2 based on the hint given by the first person without seeing section 1. After section 2 is finished, the second person leaves a hint in the same manner in section 3 for next person and so on until the piece is finished!
