From 1913 to 1931, the Schneider Trophy took place. 4 nations (England, Italy, France and the United States) competed with daring and technique in extremely dangerous speed races. Hydroracers is a game of fast races interspersed with preparation phases where each nation improves its aircraft. The game is an alternation of development and racing phases. Races: each player takes a turn to play a card from his hand and move forward on the circuit. Development: like bingo, the player picks chips from a bag of the player’s color. When a chip is drawn, the player chooses on which development he wants to invest. The number of phases is defined according to the duration desired by the players. The game ends with a final race phase. The winner of the Schneider Trophy is the one who has accumulated the most victory points during the races.
