2 hours is really not enough to play, because some machines have multiple games in one machine, and there are people queuing behind, so you can't play all the games at once, and you need to queue up multiple times to play them all. Customers who come here for the first time generally don't know how to play each game. Due to the 2-hour limit, they can't read the instructions for playing slowly (you have to fight for time to play, rather than wasting time reading the instructions). Therefore, it is recommended that at least one staff member explain the gameplay for each game, which will save time and make the gameplay clearer. It seems that there are not enough staff on site. I have to praise the staff at G/F Ninja, they are all very nice, enthusiastic and willing to listen to customers' inquiries patiently. Adults and children have fun here, and the overall experience is good! But for the price of more than 200 yuan, it would be more appropriate if you can play for 3 hours, because queuing also takes up a lot of time!
