“This is a second of these amazing challenges by Lucie Pauwels to match the Minimal Frame from the last release. Like its’ predecessor, it is a very colourful 2D packing puzzle with multiple different woods combined with an anti-slide puzzle using a very minimal frame but this time the edges of the frame are formed by single voxel pieces in the centre of each side (unlike the last one which had only 2 corner pieces). There are 9 pieces to be fit inside the 7×7 square. There is an overlap between the two puzzles with some shared pieces but the very simple ones are different.

I went to work and yet again, realised that tray packing puzzles are very difficult for me. I did manage after an hour or so to find a single assembly. It is oddly difficult to place these pieces into such an open tray. Like the Minimal frame, I was able to get many “not quite there” solutions but actually making the complete square shape proved very tough. The solution I found was satisfying but it did not fulfil the anti slide requirement. There are 2 pieces in the puzzle which must be oriented in a certain way to prevent them slipping out an edge or you must find a way to confine them to the interior of the assembly shape. A quick resort to Burrtools showed me that there are 15 possible assemblies of the square but only one of them is also anti-slide. I won’t show the final solution but once you look at it, it is a marvellous thing to behold! This is a huge challenge and very attractive! If you have the Minimal Frame then you owe it to yourself to get this one to go with it.”
