Double Trouble
Double trouble is another puzzle by Jean Claude Constantin. It consists of two linked mazes. You push a ball through each of the two centre holes and have to retrieve from the outer holes.
Artistic Ratings
The ratings I have chosen for this puzzle is 6,7,6. It is pleasant to look at and has a good aesthetic appeal. The design is interesting and its implementation is slightly rickety.
Solution (Spoilers - click to reveal)One way to solve this puzzle is to turn it upside down and position one of the balls in the entry hole. This will stop it locking the maze. Keeping it upside down, you can now solve the other half of the maze. Once that side is completed, solve the second side. Not sure if this is a cheat or if this is the intended solution.
A great puzzle.
