Invisible snakes and ladders board game New For Christmas. Condition is New. Dispatched with Royal Mail New twist on the classic board game Ideal for Christmas family fun Invisible Snakes and Ladders has no visible snakes on the gameboard. Instead, we use 80 game cards that possess unique coordinates for the heads and tails of snakes in order to create a roller coaster of a family game. Snakes can be at the top of ladders one minute and gone the next. Every game is different, and with the unique "snakes eyes" cards option, yet another variable is injected into this highly competitive, rip-roaring, compelling, and totally unpredictable family game...in fact it is a totally new and unique experience.
