Sea Salt & Paper

During your turn, you assemble your hand, maybe place cards for their effect, and decide if you want to end the round. But do you think you are the one with the most points in hand? You will have to choose: stop the round immediately or give the others an extra turn to try to extend the gap? Is it worth taking the risk? The game ends when you reach 30/35/40 points (4/3/2 players).
