What We Do

Automatic crossword puzzle generating

We have developed the world’s most robust and efficient crossword puzzle generating system. In efficiency benchmarks it outclasses any other software currently in existence by factor of 20. Quixler Core is the only software in the world capable of generating very large and complex puzzle grids in mere seconds.

We have been experimenting with an in-Design-like GUI for puzzle compilers, building a full-vector prototype, operating at 3600 DPI and offering working conditions that are unavailable in any other solution on the market. The generating system that is a part of the Quixler Core solution is cloud-based and can be run in a SaaS business model. Additionally, there can exist multiple user interfaces, with different sets of access rights and privileges, enabling remote work for your team. The software is modular and every function is available via API, so it is easy to integrate it with tools that you are currently using in your operations.

Conversion of puzzle magazine readers to digital platforms

Nokia produced a touch-screen mobile phone in the early 2000’s. Nobody cared, because mobile Internet access was not wide-spread enough for anyone to be able to make much use of the touch-screen. In 2007 Apple released the iPhone and created the single most profitable product in the world.

We believe we might be facing a similar crossroads. All puzzle content publishers tried to convert their readers to mobile or webpages in the 2010’s. For the most part the solverbase didn’t care, because many of them didn’t have access to the Internet and for those who had, the products didn’t offer much extra compared to printed puzzle magazines.

2020 is for puzzle content publishing what 2007 was for mobile phones. Access to the Internet among elderly people has skyrocketed. In the UK, in 2018, every other person aged 65+ had already bought something online. The digital infrastructure exists. What is needed next is an attractive product that makes the most of this opportunity.

The Quixler Reader App is this product. It can operate as a standard app that you run on your tablet or, in an advanced mode, can run on a tablet-like, intuitively functioning, stylus-operated device that imitates the paper solving experience of puzzles while offering unprecedentedly engaging puzzle content.

Brain monitoring & training

According to our market research in Poland, cognitive health until late age is important or very important for 90% of people aged 60+. Most of them, 70% of people, exercise cognitive fitness deliberately at least once a month. For these people, we wanted to create a product that provides cognitive health benefits as a side-effect of enjoyable interactions with puzzle content.

The benefits of using such a product are twofold. First, solving fresh and original puzzles keeps the brain fit. Here, our attention is focused on delivering optimally challenging solving experiences. If they are too easy, they don’t develop cognitive functions. If they are too difficult, they lead to frustration and quitting. Thanks to our expertise we are able to perform this optimization at the highest level. In order to craft the most suiting challenge types we began a collaboration with the SWPS University. Gaining access to scientific literature on cognitive training and the support of their neuropsychologists.

The second benefit is the constant monitoring of cognitive brain functions. Cognitive health check-ups are unfortunately still infrequent, even among elderly people. A meta-analysis (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5293981/) of studies about the prevalence of undiagnosed dementia concluded that 62% of dementia cases go unnoticed. Many diagnoses occur later than optimal. Early diagnosis improves the chances for treatment and the regulation of cognitive decline.

Interaction with puzzle content provides an effective basis for the monitoring of cognitive functions. One of the first symptoms of Alzheimer’s disease is typically the difficulty to remember newly learned information. Language-based puzzles like crossword puzzles offer methods of monitoring the rate at which solvers learn new words. Analogically, different puzzle types can be deployed to monitor changes in distinct cognitive functions. Since the performance in cognitively demanding tasks is influenced by multiple factors, including mood, alertness, tiredness and stress-levels, the monitoring process does not rely solely on the user input, but also on measures of relevant physiological states.
