A strategic, competitive colouring in game.
Two players take turns to colour in areas, each player trying to make the finished sheet look like one of two objectives.
The game ends when every section is coloured in.
At the end of the game, the players show the sheet to an impartial judge (or post it on social media) to determine the winner - the person aiming for whichever objective the judge(s) think it looks most like.
Will you focus on your picture, or on ruining your opponent's? To succeed, you'll need a balance of aggression/defense, an understanding of how things might be percieved, and a smidgen of empathy.
Though the final result is determined by aesthetics rather than maths, this is essentially a perfect information abstract strategy game.
