100 Coloured Circles. Only The Ten That You Need Must Remain!
100 coloured circles (ten each of ten different colours) sit inside a series of grids. 18 shaped blocks will together cover 90 of the circles. With each of the 45 multi-level puzzles, your task is to use a combination of logic and spatial awareness to ensure that once all of the blocks are in place, only the ten circles that you need to complete the challenge remain uncovered. Brilliant!
