Attempt board
Free daily logic game with no registration
One code. One day. The same challenge for everyone. El Código del Día is a free daily code-breaking game available in Spanish and English. Crack a secret four-colour code using logic and deduction. You have 10 attempts, colours can repeat and everyone plays the same daily challenge.
Basic rules
You have ten attempts. After each guess you receive two counters: how many colours are in the correct position and how many are in the code but placed elsewhere. These counters never identify a particular slot, so winning depends on combining logic, elimination and memory.
How to take part
Everyone solves the same daily code. You can play without an account and share your result without revealing the solution. Creating an account is optional: it lets you keep statistics across devices, join private groups and collect Aura by finishing the daily challenge and earning streak medals. That Aura can be used for optional clues after the fourth attempt.
Start today's challenge above or read the complete guide to learning how to play, the strategies for winning in fewer attempts, the private groups, the global ranking and the historical results.

Frequently asked questions
What do I have to guess?
A four-position code made from six colours. Colours may repeat.
What does the feedback mean?
The feedback shows how many colours are in the right place and how many appear elsewhere, without revealing where.
Can I play without an account?
Yes. Guest mode saves your progress and statistics in this browser.
Is there a new challenge every day?
Yes. Everyone plays the same daily code and can share the result without revealing the solution.
How do I earn Aura?
With an account you receive welcome Aura, earn Aura by finishing the daily challenge and gain bonuses for streak medals. Practice games and challenges do not generate Aura.
What is Aura used for?
After the fourth attempt, you can spend Aura on optional help: eliminate a colour, learn how many different colours appear or reveal one position. After finishing Daily mode, you can also analyse your own game or see how other players solved the code. Using Aura does not subtract points, but clues used are shown in the result.
