Show hints in/on empty cells next to filled ones saying what could come there.

It could be good to help a new player to start.

Sounds cool! Can you please explain it in a more detailed way?

• How exactly
• How are you gonna display this in case there are multiple options (or super-multiple)
• We have to remember, that we can generate compounds in any direction vertically and horizontally! How this gonna be displayed?

How

• Scan all "lines" for non-empty cells standing next to empty ones. Let call it border-pair.
• For each border-pair see what could be a continuation involving more non-empty cells next to the border.

Result list

It should be stored/associated with the cell. Each empty cell could have several non-empty neighbours. It should store sum of all possibilities.

Display

Either of these

• Show most popular one.
• Show hint in a panel listing more possibilities.
• Show a popup/hint on right-click or long press.
• Filter the list by element available on the field.
