Rocket Race is one of the Milton Bradley 'Flipsiders' games that resembles an audio cassette until you 'flip' the game open. The 2 players (starting at either Earth or Mars) compete to race their rockets to Pluto and back. On your turn you move your marker across the board the number showing on either spinner. The A spinner requires you to spend a fuel unit to use (you can refuel by landing on a planet). The B spinner only lets you drift 0 or 1 space. It is used if you are out of, or trying to conserve fuel. You might also spin an Explosion which causes you to lose all your fuel. Go to Pluto and return to your home planet first to win. - BoardGameGeek
