Deduction Sort

The color lies.

A parcel comes down the belt. It is red. There is a red box right in front of you. Wrong box.

Deduction Sort is a sorting puzzle where the obvious answer is the trap. Every level runs on a hidden rule - type, color, quantity, pattern, orientation, shape - and your job is to work out which one before the clock starts punishing you.

HOW IT PLAYS
- Drag each parcel from the belt into the box where it belongs
- Read the boxes: the samples already inside them tell you the rule
- Chain correct drops to build a combo; a mistake costs you time
- Fill a box and it ships out, making room for the next order

NOT JUST ANOTHER SORTING GAME
- The rule moves as you progress: what worked ten levels ago becomes the decoy
- Color only enters the game once you have learned to look past it
- Close categories - dogs, cats, birds - turn sorting into real deduction
- Rush orders raise the pressure without turning the game into a reflex test

BUILT FOR SHORT SESSIONS
- One hand, portrait, no walls of tutorial text
- Levels are generated, so they keep coming
- Pick it up for one minute or forty
