As the main mechanism theme of the secret room shop, the theme of Fan Cage is relatively large, and players with big brains need to cooperate with each other to complete the game, which is quite difficult, and the theme of the store "The Room That Can't Be Opened" has been rated as "2016 Best Mechanism Theme". At present, Fan Long has two stores in Guangzhou, and each store offers different themed games. There are four themes in the store in Jiangnanxi, among which the design of "The Last Code" is biased towards the industrial mechanical wind, which is a very difficult theme game, its mechanism has a lot of novelty, the rhythm of each link is relatively compact, and the fly in the ointment is that there is a lot of interference information in the final level, and the difficulty is a bit too high, and it is easy to waste time. "The Room That Can't Be Opened" is a must-play theme for high-end escape room lovers in Guangzhou, and has won the first place in the first Guangzhou escape scene. Due to the use of various technological elements, classical elements and highly retro props, the overall scene layout is exquisite and enhances the player's sense of substitution. This theme has a lot of processes that require teamwork, so at least four people should play. Its gameplay is different from the regular secret room, there are more pure physical mechanisms, and you need to complete the escape through your own groping throughout the process, but the disadvantage of this game mode is that players often don't know what to do next, and some of the tips of the store are not available at the moment, or the props are too small to trigger and it is difficult to notice, although there will be enthusiastic staff to explain before entering, but in the actual experience process, you will still feel that there are more cases of stuck. At present, the new Fanlong store on Tiyu West Road also has two themes, namely "Counter-Terrorism SWAT Team" and "Legacy of the Mysterious Island". The former is a beginner's theme, while the latter is a new theme with human-computer interaction, which is totally worth checking out for both new and experienced players.
