Daily challenge
Answer a logic, number, riddle, or general knowledge question. You get three attempts: a correct answer on the first is worth 100 points, the second 70, and the third 40. If you run out of attempts, you'll see the answer and an explanation. The calendar uses the Europe/Madrid time zone.
Visual memory
Press “Start” and watch the highlighted tiles. Repeat the sequence in the same order. Each round adds one tile and earns points; choosing a different tile ends the game.
Number sequences
Find the rule in the sequence and choose the next number. There are six prepared questions and three attempts for each one. The explanation appears after each sequence is solved.
Word challenge
Read the clue, unscramble the letters, and type the word. Answers with or without accents are accepted. You get up to three attempts per word.
