To play this game, start by understanding the map of Mumbai where you'll be making deliveries. Plan your routes in advance to ensure you can deliver the dabbas on time. Be quick in picking up and dropping off the lunchboxes. Remember, time is crucial here. As for maintenance, there aren't any physical items to maintain, but keep your strategic skills sharp by trying different routes and delivery sequences. Pay attention to the time limits given for each delivery. If you face any issues, just restart the delivery mission and try a new approach. Have fun being a Dabba Walla!
