We, like many buyers, had some difficulty climbing the castle. Like many we had one day of about 4cm which it seemed he had to fill the pan with a non-existent wall. That said, reading the explanations of other buyers comments, we found the solution. (Without cutting room with a kitchen knife). Two elements are important: secure the wall *** *** on the front of the tower (to the left when viewed from the drawbridge) and not in the middle (which there are notches). read the documentation page 7, if necessary counting slots to verify that the right parts are in the right place.
Castle closes perfectly and is very solid. (Just a little under the onslaught of little brother 2 years, but it is understood in advance!)
the castle is big enough (about 60x60) to play with others. Personally I prefer the older version, and less typed "war" of Playmobil castles where there was a "daily life of the Middle Ages" section in addition to the "knights, swords and maces." But my children are very happy (including girls)
