So, you explore and stockpile the easier colors (which are also not as contested), and if you win a blue SS it will be possible to immediately try for purple SS and finish up the set.

No Nemuri, difficulty of finding stone is different for each players. For me, the most difficult to get are green and orange. So, he has to figure it out himself.
