Please watch the AILO workshop introduction video here on Youtube and try the three puzzles below.
Last year, we had two live Zoom Discussion sessions for any students / teachers who didn’t have an AILO tutor Zoom visit in their school. These took place at 6pm Wednesday 9th December 2020 and 6pm Wednesday 13th January 2021.
Please only look at the solutions below once you have tried the puzzles yourself. There is an introduction to the solutions on YouTube and this links to the videos below:

Ireland won a team award for the first time in the 17-year history of attending the International Linguistics Olympiad (IOL) in Bucharest, Romania this week. The team received an ‘honourable mention’, placing 9th out of 65 teams (255 students) from 46 countries and territories. Kirill Korostelev, from the Institute of Education, Dublin, won a bronze medal in the individual competition marking Ireland’s fourth bronze win at the International Olympiad. Joining Kirill on the team representing Ireland were Aidan Alexander from St Mac Dara’s Community College, Templeogue; and Jacob Roantree and Michael Costello, both from St Kilian’s German School, Clonskeagh. The Olympiad challenges participants to analyse the grammar, structure, culture, and history of different languages and to demonstrate their linguistic abilities through individual and team puzzles and problem-solving challenges.
Ireland has now won four individual bronze medals, one team honourable mention and ten individual honourable mentions at the International Olympiad since 2009.
The Irish team has been selected via the All Ireland Linguistics Olympiad (AILO) since 2009, which has been run by ADAPT, the Research Ireland Centre for AI-Driven Digital Content Technology, at the School of Computing, Dublin City University. The AILO competition is currently looking for sponsorship opportunties to be able to continue to run the AILO workshop programme and competition for 2026/7 as well as attend the international competition for 2027. Further information is available at https://ailo.adaptcentre.ie/sponsor/.
(L-R: Jacob, Michael, Kirill, and Aidan with their awards.)
Each year AILO has over 3,500 students, registered with schools on both sides of the border, attending free island-wide workshops and taking part in the preliminary round and – for some – the national finals. In the workshop programme, students work together, using their problem-solving and lateral thinking skills to work our the rules of a language they have never seen before. They then go on to take part in the competition proper of the AILO where they participate in individual and team rounds. School registration is open at https://ailo.adaptcentre.ie/enter/.
The 2026 National AILO final will take plae on Wednesday 4th March in Dublin City University (DCU). The finalists represent 56 secondary schools from 20 counties across the whole island and are competing for the chance to represent Ireland at the International Linguistics Olympiad in Bucharest, Romania this July. The competition challenges students to apply logic and reasoning to decode unfamiliar languages by analysing the language data they are given to work out the ‘rules’ of the new language. These transferable skills are critical in preparing young people for a wide range of careers in computing, linguistics and language.
The finalists progressed through a preliminary round, involving nearly 1,000 competitors, held in schools earlier this year. Competing in individual and team rounds, they will vie for the honour to be one of the four winners who will represent Ireland on the international stage in Bucharest this summer.
The results of the AILO final will be released mid-March. For those who want to try the challenge, sample puzzles can be downloaded from https://ailo.adaptcentre.ie/sample-puzzles/

The team representing Ireland at the International Linguistics Olympiad has just returned from Taipei, Taiwan. The team was made up of Michael Costello (St Kilian’s Deutsche Schule), Aidan Alexander (St Mac Dara’s Community College), Patrick Chen (St Gerard’s School Bray) and Kevin Lin (Adamstown Community College). All four students did us proud with Aidan taking home an honourable mention in the individual competition.
The Irish team is made up of the top four students from the 2025 All Ireland Linguistics Olympiad (AILO) which is run by ADAPT, the Research Ireland Centre for AI-Driven Digital Content Technology, at the School of Computing, Dublin City University.
In the IOL, the students come up against over 220 of the top linguistic problem-solvers, from 48 countries and territories to tackle some of the toughest puzzles in logic and linguistics in little-known languages from all over the globe. The students faced a 6-hour individual round paper on Tuesday 22nd. They also sat a challenging 4-hour team round on Friday 25th. The students got to take part in IOL traditions like Jeopardy!, Karaoke, a Taipei city tour and a visit out to the coast to the Yehliu Geopark.
The AILO finals see teenagers solve puzzles that require lateral thinking skills and the ability to think outside the box. Students must analyse the language data they are given to work out the ‘rules’ of the new language. These transferable skills are critical in preparing young people for a wide range of careers in computing, linguistics and language.
