Level99: Level99

Huge world in a mall of "challenges" featuring 40+ rooms, scavenger hunts and "arenas" where you compete against another player. You buy time, and then use your wristband to enter the individual rooms which last 1-4 minutes. You then earn stars or puzzle pieces which you can use to change your avatar, get physical items e.g. food at the venue. 

Largely physical based games (e.g. the floor is lava, walk a plank, climbing) but some mental/puzzle and skill games also. This is what the Crystal Maze should be. In 4 hours, we tried if not completed, all the rooms and played several of the arena games. The food/drink on offer was also excellent (far better than expected). Be prepared to get (mildly!) bruised playing some games and some upper body strength required for some of the physical games. 

Played during term time during the day, but imagine at weekends/evenings it would be extremely busy with teenagers - so ideally plan the timing of your visit to avoid so you don't need to wait for rooms to be available. Possible to visit without a car (we were in Boston, and took the commuter rail to Natick and then got an Uber easily).
