Voltorb Flip: Row Permutations

0 Extra Points Left: Row is cleared. All remaining cards are 1s or Voltorbs.

1 Extra Point: One 2 is left in the row. No cards can be 3s. Rows where only 1 extra point is left are called 2-rows.
- 2P, 4V: One 2 is in the row; rest are Voltorbs. If a card is part of a null row, it is a Voltorb. Also applies if V is one less than the number of remaining cards (3P, 3V, and one card revealed to be a 1).

2 Extra Points: Either one 3 is left, or two 2s are left.
- If only two active cards are left in the row, and one of those cards is in a 2-row, the other card cannot be a Voltorb. Either that card will have a 3 (which will clear the row), or both cards have 2s.
- 3P, 4V: One 3 is in the row. Cards part of null rows or 2 rows must be Voltorbs. Also applies if V = RC - 1. Called 3-rows.

3 Extra Points: Either one 3 and one 2 are left, or three 2s are left.
- If only 2 active cards are left, both are safe and can be opened. One will be a 3, the other a 2.
- If 3 active cards are left, and two are in 2-rows, the third is safe. If it is a 3, one of the other cards is a 2; if it is a 2, both other cards are 2s.

4 Extra Points: Either two 3s are left, one 3 and two 2s are left, or four 2s are left.
- If only 2 active cards are left, both must be 3s.
- If 3 active cards are left, and two of them are in 2 rows, all three cards are safe.
- 6P, 3V: Two 3s in the row. Cards part of null or 2 rows must be Voltorbs. Similar situations can apply depending on revealed cards (7P, 2V with a 1 revealed). Also called 3-rows.

5 Extra Points: Either two 3s and a 2 are left, or one 3 and three 2s are left. If only 3 cards are left, all three are safe.

6 Extra Points: Either three 3s are left, or two 3s and two 2s are left.
- 9P, 2V: 3-row.

7 Extra Points: Three 3s and one 2 are left.

8 Extra Points: Four 3s are left; only of concern if the non-3 card is a Voltorb, so it is a 3-row.
