landmine protect
Buy a shield that will be placed on a given word. A shield will defuse all landmines placed on that word, and will prevent further landmines from being placed on it.
A shield is a very powerful item, that'll cost 500 points for any given word. You can however add a message that will be sent when trying to place a mine.
