Games/Puzzels

Can we have a game thread?

I have a puzzel,

There are 4 people, they all need to get across the bridge, because it's dark they need to take a torch across each time. Person 1 takes 1 minute to cross, person 2 takes 2 minutes to cross, person 3 takes 5 minutes, person 4 takes 10 minutes.
They only have 17 minutes to cross the bridge because that's when the cannibals will get there.

Hint: If person 1 crosses with person 4 then it will take 10 minutes for them because they both go at the same pace. Also, they only have torch which they need to keep on taking backwards and forwards.

hello eva
do they all go togther?

you most probably know this one anyway
a man has only 4 things, a boat, a fox, a rabbit and a bag of grain. and he needs to take them across a river but his boat can only 1 thing at a time, and if he leaves fox and rabbit together the fox will eat the rabbit and if he leaves rabbit and the bag of grain together the rabbit will eat the grain. how will he get all his things across the river?

Ooops, I forgot to write that only 2 people at a time can cross.

As to the answer to yours, he takes the rabbit, then the bag of grain, he takes the rabbit back to the first side, then he takes the fox to the other side, then finally the rabbit again.

They need to bring the torch back each time. And I think the ammount of time might have been 19 minutes.
