Jaiho Spin: Must Every Card Group Have the Same Length?

Two groups contain three cards each; another contains four.

Editorial note: This is a conditional card-rule teaching example, not a verified description of the named platform.

Two groups contain three cards each; another contains four. Is the longer group invalid? For a Jaiho Spin rules article, the answer must come from the size condition, not from the neatness of the layout.

Minimum is not exact

Suppose an exercise allows sequences of at least three cards. Under that condition, both 3♠–4♠–5♠ and 9♥–10♥–J♥–Q♥ meet the length requirement. Their different lengths do not create a fault. If the instruction instead says exactly three cards, the four-card group fails that particular test.

Length is only one check

A group can be long enough and still fail another condition. Three unrelated cards do not become a sequence simply because the minimum is three. Suit, order and any permitted substitutions require separate checks under the chosen rules.

When explaining a complete hand, list each group’s length and then apply the actual conditions. Equal-looking rows are a display choice. Unless the rule demands equal sizes, forcing every row to match introduces a restriction the text never contained.
