Cast Coaster is shiny, pretty and seemingly simple puzzle. Disassembling it is a straightforward task, but the difficulty arises when you try to put it back together. The puzzle consists of three triangular-shaped pieces which have to be stacked on top of each other in a proper manner. Solving Cast Coaster does not take too much time and effort, but is definitely fun while it lasts. Overall, this is a very good puzzle and it deservedly receives my recommendation.
