Deal the entire deck out to all players as evenly as possible.

Whoever holds the five of a chosen starting suit plays it first to the center of the table.

Players take turns, in order, playing the four or six of that same suit next to the five already on the table, then extending the run outward in both directions as more cards become playable.

A player who cannot play a valid card passes their turn and keeps their card.

Once one suit's run from ace to king is underway, players may also start new suits by playing their fives when able.

The first player to play their entire hand wins the round.
