No worries, I just wanted to make sure I understood you.
BTW: I personally was having a hard time winning the Witch Hunt game.
Taking the time to aim carefully backfires as the AI will launch their balls at a very fast rate, so unless you can hit 100 and the bulls eye consistently, taking your time to aim won't likely result in a win.
A friend said she won by simply button mashing the launch button saying that what she lacked in accuracy she made up for in the number of balls launched. I tired that a few times and never won any race.
Finally, I tried a different tactic, each shot I would VERY quickly adjust the aiming arrow to be close to straight up, and set the power to less than half. This allowed me to launch more times and hit enough high value targets to win the race very consistently.
UPDATE: I've been told that another easy win is to just move the launcher all the way to the right or left and use full power at apparently it will go into the 150 point target enough times to insure a win.
If all else fails, you can try and get enough people to fill a multi-player game, and agree to take turns winning each game, but keep in mind, if you don't have enough people (max 6) then the game will still add AI, who won't make it easy for anyone to win.
Also, in case anyone was wondering, you get the same reward whether you win a multi-player game or single player game.
