Rules[edit]

Falling Letters Example.png Falling Letters Example Solution.png

Place letters into some cells in the grid. Same letters cannot share a side, and blank cells cannot share a side. Each outlined region must be filled in alphabetical order, starting with ‘A’, from left to right and top to bottom. Each outlined region contains at least one blank cell. Cells with the letters form a single connected area.

(Rules and example from WPC 2017 IB)
