Kings to Empty Columns
Level: Basic
Move a King to open face-down cards and start a long sequence.
The only card that can fill an empty column is a King. Which King you place determines the direction of the alternating-color sequence that will build in that column.
When possible, choose a King whose move also flips a face-down card. That opens information while making use of the empty column — two birds with one stone.
If you already have an opposite-color Queen ready, favor a King you can immediately extend with that Queen, so you start a long build.
