Green Leprechauns

Assist the leprechauns to cast their green magic and they will reward you handsomely! Your goal in this game is to place leprechauns onto the grid so as to turn the whole area green. When the game starts, you will be given a 10x10 grid which contains a number of shamrocks. Some of the shamrocks are marked with numbers, which indicate the quantities of leprechauns in the horizontally or vertically adjacent blocks. If a shamrock is not marked with a number, you can put any number of leprechauns beside it. A leprechaun can turn all the blocks that he can see green, but note that he cannot see through a block which contains a shamrock, and the leprechauns should not be seeing each other. Click an empty block to place a leprechaun, and the blocks that the leprechaun can see will all be turned into green color. You may also click the cross button on the right of the grid to mark a square which does not contain a leprechaun. The amount of time you have spent will be recorded at the top right corner of the screen. Will the mischievous leprechauns grant you wishes or will they escape from your hands?
