Not everyone codes the same.
Two challenges. Two ways to compete. One shared mission: to find Spain’s most talented tech youth.
If you're between 15 and 18 years old and programming is more than just a subject, Code Hunt is for you.
Take part, choose your challenge and compete for a 30% discount on the first year of IMMUNE’s Bachelor’s Degree in Software Development Engineering for a group of up to five people taking part in the challenge together.
Some people enjoy solving complex problems for days. And some people prefer to get straight into action, thinking quickly and resolving under pressure.
Code Hunt is born to detect both profiles. Here we don't measure memory or theory: we look for logic, judgement and real ability to build solutions.

FAQs
Preguntas frecuentes
What challenge should I choose?
If you're looking for a more in-depth, technical experience with more development time, your choice is Emergency City. If you prefer a faster, more direct, and conclusive test, you'll probably be a better fit for Repartidor Imposible.
Is the prize different depending on the challenge?
No. Both Emergency City and Repartidor Imposible offer the same final reward: the chance to claim a 30% discount during the first year of the programme for a group of up to five people taking part in the challenge together.
Do I need to know a lot to sign up?
You don't need a specific formal itinerary or mandatory language to participate. What's important is your genuine interest in programming and your problem-solving ability, although Emergency City demands more technical autonomy than Impossible Delivery.
Can I participate if I'm a minor?
Yes, provided you meet the age requirements and have the appropriate authorisation from your father, mother, or legal guardian.
Is there a cost to participate?
Entry is free for both challenges.
