How to play

The game

Each puzzle shows a sequence — or a 3×3 grid — with the last figure missing. Pick the option that truly continues the pattern. You have 60 seconds: a correct answer adds 2 seconds and points (a streak grows your multiplier), a wrong one costs 3 seconds.

Three levels

Foundations — one rule, one thing changing. Superposition — three rules at once, plus 3×3 matrices. Composite — five-attribute glyphs, no pity.

Where it comes from

nth is an abstract-reasoning trainer in the spirit of visual IQ tests like Raven’s Progressive Matrices. Every figure is generated and self-checked in your browser, so the puzzles never run out. The name is the puzzle itself: find the nth figure. Made by kermesse.eu.
