I see there isn't any guides yet so I thought I'd make one. An important thing to understand in this speedrun is that you don't need to win, here are all the games and the basic stats behind them.

Yatzee- Play the game normally, but as soon as you get a match, play it, don't save up.

Clue- Accuse as soon as possible, it is going to be wrong, but that makes the other person win as fast as possible.

Life- If you go first, choose university, this is because the AI will choose the opposite and does slower menuing in university. If the AI goes first always choose career.

Twister- Play the game normally.

Mouse Trap- play the game normally but pull the trap no matter what.
