Jäynä is essentially a cheerful, good-spirited prank that delights both the prankster, the target as well as the outsiders at its best.
In the below game, move blocks with arrow keys or by swiping and merge blocks with equal values together. Scoring higher points unlocks stories of the all-time pranks through decades.
34th Jäynä Competition, the contest on this academic year's best jäynä is already on! Design, implement and document an original, clever jäynä of your own and take part in the competition at jayna.fi.
The best jäynäs are awarded heroically in the glamorous Jäynä Finals in the spring 🎉
