Here's what you should do, first score 3-4 goals in the first few seconds. This should be easy to do, the computer's normally a slow and easy opponent during the first couple of goals.

Now you have one of two options:
-Drop the ball in your goalkeeper's area but make sure that your goalie does not pick it up. The computer will keep circling around the ball but never really pick it up, this way you can just leave the game running and go do whatever you wanna do till the timer runs out.

-The second option is to simply leave the game running till the timer runs out. The computer usually scores a maximum of 2 goals (3 if you are unlucky), so you still win.
True this is no scoresending or "speeding" but it makes it easier to multitask while playing Yooyuball since you technically play for only a minute, this way the Altador won't steal your full attention. I hope this helped~
