How good is this question! Before each game, the game master gives an introductory briefing. If you need a light to get through the game - we will give you a flashlight, otherwise - that is the game's intention. Please do not use your phone when playing. We have surveillance cameras installed in all of our rooms for security reasons. In case we notice a violation of this rule, the game will be stopped, and you will be asked to leave. Without any refund.
