MPS-LightUp 2006

When you're fed up with Sudoku and Kakuro, try MPS-LightUp. The aim is to 'Light Up' every empty square by placing bulbs on the grid. Each light bulb illuminates the square it is on, plus all squares in line with it horizontally or vertically. No bulb may illuminate another, and some squares must have a certain number of bulbs placed around them. Version 2.11 now includes puzzle scoring, which adds the incentive not to guess your way to the solution, and high scores to track your progress.
