This 1920s IQ test was invented by pioneering American psychologist, Dr. Grace Arthur. Stenciletto recreates her work as a fun game to challenge your thinking skills.
Stenciletto is a shapes game based on an IQ test for children created a century ago - reimagined as a fun game.
The Stencil Design (IQ) Test was developed by Grace Arthur in the 1920s. 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.
This cognitive game is suitable for all ages and abilities. There are a range of levels, from very easy to very challenging, with a free training level. And, just like Grace Arthur’s IQ test, it's designed to make you think.
Many of the stencils in the game are from her original test, with a few new ones added by us. To date, we’ve only been able to see some of her designs, but we know more exist. If we ever find them, we’ll add them into the game.
What we don't know is how Grace Arthur timed or scored her IQ test, so in reimagining it, we’ve made these decisions…
- The activity is timed
- Unlimited attempts allowed
- You can get help
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.
You can ask for help. At the bottom of the puzzle screen is a Helping Hand and a View Solution button. Alternatively, you can reset the puzzle and start again.
Stenciletto has been developed over 10 years. At the heart of it is our son who has learning disabilities, a visual impairment and cerebral palsy. The game was designed to help him improve his visual perception skills and problem solving abilities, whilst reducing his urge to tap randomly.
The game is navigable using colours and symbols, so is usable by people with limited reading ability. It has been tested with our son’s friends at Mencap, a UK charity for people with a learning disability. Most of them got it and enjoyed it.
Can you solve it?
The game works like this: solid and cut-out shapes (stencils) are placed one on top of another to make a pattern. You must match this pattern precisely, starting with the solid shape at the back and finishing with the top shape.
There are 3 simple stages… LOOK, THINK, TAP!
LOOK! What can you see? Good visual perception is key to solving the puzzles. 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.
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. The only shape that's fully visible is the top one, so that's the easy part. The shape at the back is always solid - so that’s easy too. But what shapes are in the middle? That’s the tricky bit for you to solve.
TAP! Finally, restraining your impulsivity is essential. The urge to tap a shape can be overpowering, but trial-and-error behavior rarely solves a problem correctly. Taking your time and using your intelligence is a far more effective way to solve a problem. Once you work out a solution, simply tap the shapes to see if you’re correct.
However, some words of warning!
- Once you tap a shape, the timer starts.
- Tap before you think and you’ll fail.
- Think first - and you’ll succeed!
Most puzzles are solvable in less than a minute, and there are 15 puzzles in each game. And, as a reward for completing 15 puzzles, you’ll win a fun animated Smiley character!

Ratings and Reviews
Fun but settings don’t work
I have had fun solving the puzzles. I don’t mind the time limit, but maybe have an option to have this switched off, so every player can enjoy the game their way. I haven’t had an issue with in app purchases so far and have parental settings due to family sharing. I managed to purchase the immortality which has freed me up to play as often as I like. This cost £2.99 I like that it’s a one off payment and not some weekly or monthly subscription. I know someone has to put the time in to make such things. But I do think it’s wrong how other games/apps think you have an endless money bank to pay for a basic game on a weekly/monthly basis. So this game suits my pocket. I dropped a star because I do have one issue. I switched off music and sound effects. But every time I open the game to play, it plays music. If your customer has chosen to mute all sounds they have done so for a reason. Please fix this. Otherwise I enjoy the puzzles

We've fixed how the sounds works and updated the music settings and controls in the latest version, it's in the App Store now. We'll be adding a 'casual' mode in a coming update.
Great game but needs a bit more work
I downloaded this after reading about it in the paper. It’s been great fun so far, pleasantly taxing and really great practice for thinking through rather than impatiently responding, but at present it’s hard to get back and forth between levels and menus. Also I puchased ‘immortality’, but it didn’t do anything, and am stuck waiting for lives like before.

We've changed the way lives are topped up in 'immortal mode'. It was a bit confusing - sorry. Check the 'hints & tips' for more details on modes and puzzle strategy. The update is in the App Store now.
Time limits and scoring stop it being fun
What should be a relatively relaxed and cerebral puzzle game is spoiled by tight time limits on each level, and scoring that punishes you for taking too long. It’s a shame because the basic puzzle mechanic is very clever and enjoyable to solve, but not when you have a timer ticking down at the bottom of the screen. I’d happily pay for a version of this game where I was given time to consider each move and not given arbitrary scores for time taken and “accuracy”.

The next major release will add a 'casual' mode. Think that will suit you. It will be ready in a few weeks.
