In each of the 24 compartments of the Exit Advent Calendar for ages 10 and up, a tricky puzzle challenges the player. To find the right door for the following day, the puzzle must be solved in the room. To do this, clues can be found in the richly detailed illustrated compartments, on a total of 47 puzzle cards with a wide variety of puzzle types. Who cleverly combines, finds the solution, and thus to the symbol of the following door. This is the mission: In a yellowed letter from 1803, which appears in a historical atlas, the explorer Lord Ernest Pickleton reports on a hidden Maya temple in Guatemala. Its exact location, however, is a mystery to be explored. Exploring the hidden temple is a challenge: only one room may be entered each day. The journey was successful if the heart of the temple was found within 24 days. Now clever powers of deduction and creativity are required. Each family member can contribute his strengths. But don't worry, if you get stuck, a table on the back of the pack with 2 hints per puzzle and a breakdown of the solution will help.
