Flood Duel
A head-to-head colour flood: spread from your corner while the AI spreads from its own. You can never take the AI's current colour, so every pick is also a block. Beat 15 ever-smarter rivals.

About the game
Flood Duel turns the classic colour-flood puzzle into a head-to-head race. You start in the top-left corner, an AI starts in the opposite one, and each turn you pick a colour: your whole region switches to it and swallows every touching tile of that colour. Whoever owns more than half the board wins.
The catch is that you can never pick the colour the AI currently owns, and it can never pick yours. So every pick also decides what the AI is allowed to take next turn. Fifteen rivals, from Puddle to Leviathan, each on a fixed board that was checked to be winnable, and later ones play smarter. Bigger wins earn more stars.
