The game has two players. On the board are four eels, three 3D escalator pieces, a start and a finish line.
The concept is for the player to make it to the finish point before their opponent. By rolling a pair of dice, they move a certain amount of spaces each turn. Instead of numbers, the dice has three sides with one eel each, and three sides with one escalator each. If they land on the eels, they'll be moved back a certain number of spaces by "riding" the closest eel, closer to the starting point. If they get an escalator, you "ride" the nearest escalator, moving you upward and towards the finish.
If the player rolls two eels, they move down the board towards the eels. If the player rolls two escalators, they go up the escalators.
If the player gets four eels, they lose. If the player gets three escalators, they win.
