Stenciletto Avis

The game was designed to help him improve his visual perception skills and problem solving abilities, whilst reducing his urge to tap randomly.

Stenciletto is a shapes game based on an IQ test for children created a century ago - reimagined as a fun game.

You need to really study the shapes, rather than just quickly glancing: most mistakes are due to poor visual perception rather than incorrect logical reasoning.

The game works like this: solid and cut-out shapes (stencils) are placed one on top of another to make a pattern.

As the timer doesn't start until you tap a shape, you can take as long as you need to study the the shapes, think, and plan your answer.

The game is navigable using colours and symbols, so is usable by people with limited reading ability.

Many of the stencils in the game are from her original test, with a few new ones added by us.

THINK! Accurate logical reasoning is absolutely vital! Because you can only see a little bit of each stencil in the pattern, you must work out which stencils are in use.

You must match this pattern precisely, starting with the solid shape at the back and finishing with the top shape.

She was an innovative psychologist who developed a range of non-verbal reasoning tests, and demonstrated the many of the verbal IQ tests in use were discriminatory.

The urge to tap a shape can be overpowering, but trial-and-error behavior rarely solves a problem correctly.

The Stencil Design (IQ) Test was developed by Grace Arthur in the 1920s.

Most puzzles are solvable in less than a minute, and there are 15 puzzles in each game.

The shape at the back is always solid - so that’s easy too.
