It's night time, and this family must find its way across this bridge. Can you help them make it safely to the other side?
Only 1 lamp is available, and it only has light for 30 seconds total.
Only 2 people can cross at a time, and they must have the lamp with them.
Each person walks at a different rate: 1 sec, 3, 6, 8 and 12 seconds.
A pair crossing together will walk as fast as the SLOWER member.
One person has to come BACK with the lamp so another can cross
To choose a pair, click on two of the face icons at the top of the screen and click on 'GO'. You will see the seconds timer showing you how much lamp time you have left.
