Where can I play really fun babysitting online games?

I love playing baby games online like nanny mania. But i can not download.......So I need an onli ne one.

What are some games and activities to play while babysitting 3 boys?

I babysit for this family quite often. Their kids are 7, 5, and 2. I always bring games, activities, videos, and books for them so they don't ever get bored while I'm there. (All 3 kids are boys!)Normally I do "themed" nights (We've had Baseball Night- play baseball, eat hotdogs for dinner, and watch a baseball movie. We've had 4th of July- fireworks craft and make cookies with red, white, and blue icing. We've had the Olympics Night and so on...) I'm kind of running out of ideas and activities and games to bring. Normally I'm there at night for 2 or 3 hours (7-10 pm) and the 2 year old is asleep by 7:45 and the other kids go to bed at 9:00... What are some more activities I can bring or games we can play that will be fun for them???
Take into consideration that they really don't like to play games that involve competition... One of them always loses and cries.
