I've heard of All Fours! My grandpa used to play it on digs and he taught me when I was a kid. I think I remember how to play...

[He honestly hasn't played anything but Duel Monsters for a long while, which is why getting his old deck of cards is such a refresher. Yuugi tilts his head, ears flicking in contemplation before he nods to himself and rests his elbows on the table, thumbs pulling the cards apart.]

The player with the more valuable cards in tricks scores a point, but Sixes and Jacks are worth a bit more. The players are dealt six cards and a trump is involved...I think.
