Helping me Helping you

Please be attention with me because the game has a strange and unique idea. The game is about 4 players entering 4 different rooms and each room has a different puzzle, but there are puzzles in the rooms that have solutions in other rooms. For example, if there is a puzzle in the first player’s room and he does not know the solution, he will call the other players in the other rooms and say, “I do not know the solution to this puzzle, is there someone who has the solution?” He will find that the puzzle has a solution with the fourth player or the second player, for example.But you must hurry to solve the puzzle before the time runs out (10 minutes).In conclusion, everyone helps each other. I hope you like the game:)

Note:There are puzzles which don't need helping
