 Also located on the runs are moguls ( bumps ) that , when hit , causes the racer to go airborne and slow down slightly when landing . While airborne , players can perform freestyle tricks and earn bonus points . However , if the player botches the trick , the racer may tumble and fall , losing time . At the end of each run , final scores are calculated based on the amount of time remaining on the run and points scored from completing freestyle tricks . If the player earns enough points , they may race the next level " solo " ( without other skiers onscreen ) . The points earned in qualifying runs convert to additional seconds on the solo run timer . The high scores on each of the runs are saved in memory until the console is powered off .
