You are given 9 "building complexes" and 1 water tower. Your objective is to lay them all into a City Block. You may start with the water tower in any of the 13 holes that are in the base. Now see if you can fit the rest of the buildings in place. If you are successful, try it with the water tower in a different starting point. Keep going and see if you can find all 13 possibilities! A fun and attractive puzzle that is quite challenging regardless of where you start the watertower. Measures about 4.75 x 4.75 x 2.75" We have recently made this puzzle even more attractive by toning some of the wood in the building. Very nice looking puzzle.Designer of this puzzle Jean Claude Constantin of France.Level of Difficulty: Level 4
