Quick Reminder: What is a Two-String Kite?

A two-string kite uses one digit with exactly two places in a row and exactly two places in a column. One end of the row pair and one end of the column pair sit in the same box. The other two ends can’t both be false, so the cell that sees both of them loses the digit.

How to Practice

  1. For one digit, find a row and a column where it has exactly two places each, with one end of each in the same box.
  2. Remove the digit from the cell where the far end of the row and the far end of the column meet.
  3. On the board, tap each of those candidates to remove it.
  4. Press Check. On your first try you see how many you found; on the second, the ones you missed get a dashed ring.
