I got a V-Cube 8 for Christmas 2019. It now takes me approximately one hour to solve it. I need to combine the algorithms of the 3x3x3, 4x4x4 and 5x5x5 cubes to solve it. A good workout for the gray matter!
I like a lot of different kinds of word puzzles and jigsaw puzzles. I too don't have a lot of table space to do them so I use one of those large white boards you can write on and erase.
It is large enough to hold big puzzles and light enough to carry easily. It can be set on a dresser or any surface out of the way when I'm not working on the puzzle. The frame around it also helps to keep pieces from falling off if is bumped.
I'm thinking about buying one of those large mats that jigsaw puzzles are done on. They can be rolled up & put away. I just want to be sure that after I complete a puzzle I can remove it so that I can reuse the mat.
