Today in the new online game Brain Challenge we invite you to test your intelligence and try to solve some pretty interesting puzzles. In front of you on the screen you will see the playing field on which the cake will be located. There will be a candle installed on it, which you will need to burn. Clouds will be visible in the sky above the cake. Some of them can form lightning. They will be gray in color. You will have to drag one gray cloud to connect it to another. Having done this, you will see lightning strike and light a candle on the cake. For this you will be given points in the Brain Challenge game.
