My team came to Lost Canada because of a Groupon and we did the Aching Time of Pi.
Our first impression upon entering wasn't great. As you walk up the stairs you activate sensors that play a sound every time you take a step. It was quite annoying. The lobby was grim, poorly lit, and the only game to play was one that administered an electric shock to the loser. The men's restroom smelled disgusting. The only redeeming quality were the free chips being offered as a snack.
When we entered the room, is was quite dark, which ultimately frustrated us because it made it more difficult to solve the puzzles. The puzzles weren't enjoyable, and the room was falling apart. Even worse, this company uses an RFID system to unlock the door but the RFID card had broken and so we could not use it to escape. The staff had to let us out. But it took them a couple minutes to notice we had completed the room. So we stood around in confusion.
Moreover, it's not like he RFID system contributed to the room in any way - it could easily be replaced with a regular (functioning) lock and key.
Overall, not a great experience. Would not go back. Do your research and find a better company, the Groupon is not worth it.
