Flood Frontier
Flood Frontier starts from the top-left connected region. Choose a new color, absorb every edge-connected cell of that color and keep expanding until the complete board belongs to you.

How to play
- Choose a color touching the current territory boundary.
- The whole territory changes to that color and absorbs every newly connected matching cell.
- Capture all cells before the move budget runs out.
What to expect
- Diagonal contact never connects territory and a no-gain color does not consume a move.
- Every generated board stores and replays a successful path before it is served, so unsolvable boards fail closed.
- Practice includes undo and reset; scoring rewards complete boards over every incomplete result.
Difficulty
Easy is 6×6 with four colors, Medium is 8×8 with five, and Hard is 10×10 with six.
