This is the roof jump game! All you have to do to win is try and trip them while they're jumping. The way to do that is that you say who you wanted to trip, then you spell part of a word and they have to guess the rest.

Here's an example:

I target "name". Here's the word hint for that person:
AW--O-E.

If they guess wrong they trip over the roof and are out of the game.
Hope you enjoy!
