Shape Spy

The game

A grid of shapes is posted under a rule — ALL RED, ALL CONVEX, ALL UNDER 24° — and exactly one shape secretly breaks it. Spot the traitor before the timer burns down and the red SPOTTED stamp drops on its cell. Rounds escalate from six tiles to over twenty and rotate through eight rule families: kind, color, fill, side count, size, tilt angle, convexity and sharp corners. A false accusation flashes the board red, resets your streak and eats a third of the clock, so second-guessing costs. Everything is drawn as a Bauhaus poster: circles, triangles and squares in red, yellow and blue on cream with big geometric type.

How to play

• Click (or tap) the one shape that breaks the rule posted at the top of the screen.
• Start a run with the START INSPECTION button, or press Space/Enter.
• A correct find freezes the round for the SPOTTED stamp, bursts confetti and scores 100 plus a streak bonus (x30) and a time bonus (x10 per remaining second).
• Wrong accusations subtract time (at least 2.5 s), reset your streak and wobble the tile you blamed.
• The striped bar at the bottom is your round timer; when it empties, the run ends and your findings score, best score and Bauhaus rank are shown.
• Press P or Esc (or the ROUND chip) to pause; click or P again to resume.
