Speed Circuit is a Formula I racing game published by 3M in 1971, and then republished by Avalon Hill in 1977. Description Speed Circuit is a racing game for 2-6 players (with an option to add up to six more players). Drivers customize their cars and then race them on a variety of Formula I tracks. Components The Avalon Hill edition includes: four piece folding mounted 32" x 22" game board with three Formula I race courses ( Monaco, Monza and Watkins Glen.) six cars (metal in the original edition, plastic in subsequent printings) pad of player logs 4-page rulesheet six-sided die Building cars Each player starts with a car with a Start Speed of 40 mph, Acceleration and Deceleration of 20 mph, Top Speed of 140 mph, and 4 Wear Points. Each player has a pool of 5 points. Using a pool of 5 points, each player spends 0, 1 or 2 points on each of those categories, resulting in: Start Speed (40, 60 or 80 mph) Acceleration (20, 40 or 60 per turn) Deceleration (20, 40 or 60 per turn) Top Speed (140, 160 or 180 mph) Wear Points (4, 5 or 6) Setup The players select which of the three tracks to use, and how many laps each race will be. Start position is determined by start speed — the player with the highest start speed gets the inside lane front row start position. The second fastest start speed gets the middle lane front row, and so on. If two or more players have the identical start speed, their order is determined randomly. Start The players write down their speed for the first turn (their listed Start Speed) on their player log. A player can choose to increase their start speed by 20 mph, but risks stalling (rolling a 5 or a 6 on a die), which leaves them on the start line until the second turn. The drive can again try to increase start speed by 20 mph on the second turn, but a car that stalls two turns in a row is out of the race. The car in the lead moves first, moving 1 square ahead for every 20 mph of speed. The second car then moves, and so on. A car cannot voluntarily leave the track if its path is blocked by another car — a collision results instead. Race Once all players
