During a round a player may choose to not reveal yet if they aim to make a higher-scoring hand such as a quad (4 of a kind or a 4-card straight flush).

After end of round and scoring, shuffle deck and deal a new round. Players now pass to the right. (Third round passes left, fourth right, etc.)

Scores:
1 point for SK
3 points for quad
3 points for two SKs (No card can belong to more than one SK)
5 points for SK + quad (same rule)

First to N points wins (10 or whatever agreed on)
