The Formula 550 is a strategic card game. You "race" by playing Acceleration cards to accelerate and Attack cards to stop other players. Once stopped you need to play Service cards before you can move again. Super cards protect you from the attacks. Your objective is to be the first player to travel a distance of 550. You are the blue player. Your dashboard and cards are at the bottom. The green number on the dashbard is your speed. The white number is your distance. You play Acceleration cards to increase or decrease your speed. The distance you travel depends on your average speed for your turn.
You can stop players using one of four Attack cards: (1) Out-of-Gas, (2) Flat Tire, (3) Sharp Turn, and (4) Deer Crossing.
If you are attacked, you may need to play one or two Service cards.
The deck also contains four Super cards: (1) Super Gas Tank, (2) Super Tires, (3) Super Steering, and (4) Super Radar. These Super cards provide special features to protect you from Attack cards. There is only one of each Super card in the deck.
A Double Time card doubles the time of your turn to two or four.
HOW TO PLAY 1
You start with five cards. Your initial speed is zero and you do not need
service. On your turn you pick a card. Your options depend on whether or not
you have been attacked or need service. If you have been attacked, your status
indicator will be yellow. If you need service, your status indicator will be
red. Otherwise, your status indicator will be green.
No attack card on you: If you do not need service and no
Attack card has just been played on you, then you may play or discard any card.
If you discard, then your acceleration equals zero and the time for your turn
Attack card on you: If an Attack card has just been
played on you then you can (1) play the relevant Super card, (2) play an
Acceleration card to slow down to less than 25 if the Attack card is a
Deer Crossing or Sharp Turn, or (3) discard.
HOW TO PLAY 2
If you play the relevant Super card, you pick and play another card and your turn time is doubled.
Service is needed: If you need Service, then you can
discard or play any type of card except for an Acceleration and Double Time
card. At the end of your turn your final speed and position are calculated. If you are playing the manual version, you may be prompted with a question about your turn, depending on the type of card you played. Correctly answering questions increases your potential score. See the scoring section to see how your score is calculated. Play continues until all cards have been picked or someone travels a distance
of 550. If no one has traveled a distance of 550 after the final card has
been picked, then all cards in the discard pile are reshuffled and play
The Formula 550 is a race. You play Acceleration cards in order to change your
velocity and then use the average velocity for your turn in order to determine
the distance that you travel. In order to simplify the Physics of
the game, we assume that the direction that you are traveling is not
relevant and so the equations for straight-line motion apply.
Acceleration is defined as the change in velocity divided by the change in time:
a = (Vf - Vo)/(tf – to) = (Vf
– Vo)/t if to = 0 where:
Vf is the final velocity (at the end of your turn)
Vo is the initial velocity (at the start of your turn)
a is the acceleration (during your turn)
t is the time, either 1, 2, or 4.
The equation for acceleration can be rewritten to determine your final velocity:
(1) Vf = Vo + at
The average velocity for your turn is given by:
(2) Vave = ½(Vo + Vf)
The distance that you travel during your turn is given by:
(3) dturn = Vave t
The distance that you travel during your turn can also be found using
equation (4). Equation (4) can be derived from equations (1) to (3).
(4) dturn = Vot + ½ at2 Your total distance traveled, or your position x equals the position
at the start of your turn plus the distance traveled during your turn.
(5) x = x previous turn + dturn
Your score is equal to your distance traveled.
Your score is the larger of the two:
(1) Your distance (2) (Your distance - Average distance of competitors)*(Number correct)
You get a chance to solve a problem when you play an Acceleration, Double Time (if V > 0), or Super Card.
