In WarioWare Gold, the player must complete "microgames", which are small minigames with short time limits. If the player succeeds in a microgame, the game moves onto the next. If the player fails, they lose one of four lives. If the player runs out of lives, the game ends and the player's high score is displayed. The game will naturally speed up every few microgames, with its difficulty increasing each time a boss microgame is completed. (wikipedia.org)
