This is really one of the good brain challenge games for adults. Here is the answer of this brain teaser game.
Answer: 3 bulbs and 3 switches puzzle solution:
Turn on the first switch and wait for a while before turning it off.
Then, turn on the second switch and enter the room to control bulbs. Two of the bulbs should be off while one is on.
The one that’s on and still lighting is controlled by the second switch.
Now, touch the bulbs that are off. The one that’s cold is controlled by the third switch, and the one that’s warm is controlled by the first switch.
