Basic Maths Flash Game 3

I have an online game to be made. This is the third in the series. This one in particular already has 90% of the graphics and animation made. It just needs some updates and alterations in order to change the process of the game. The game is essentially battleships. It will involve in-putting mathematical co-ordiantes in order to find 3 items of 'buried treasure' by some gold miners. It will require one player and two player mode. Single player will involve 3 random items on the co-ordinate grid to be found by the player. Two player will involve players next to each other hiding the items. Then taking it in turns to find each others hidden items. More information available.
