Just bare in mind if you do jump your time while a room is panicking it wont reset your rush cool down correctly and you'll miss out on xp. Then rush the room until it can't be rushed anymore and then jump another 20 minutes. I suggest just jumping 20 minutes at a time while leaving the game open (which makes it a lot easier to do on PC). But you can also change the time on your xbox/PC and speed the whole thing up. The finally thing I would suggest and is up to you as its kind of cheating. I recommend having at least two dwellers with these stats in the lab, then all you do is simple rush the room, with higher luck you can risk a higher failure percentage, but I wouldn't risk going over 50% unless you've got luck maxed at in which case you can push to around 60 to 65%.

Then find a dweller with high Intelligence and ideally high Luck as well, you can also argument this by put them in formal ware and training them in a game room to boost luck or put them in a lab coat and train them in the class room to boost intelligence. Build 3 of these next to each up then upgrade them to full. A diner is placed automatically at the start of the game on the top level of the vault.The first thing you'll want to do is get enough dwellers so you can build a science lab which allows you to produce stimpacks.

In Fallout Shelter: The Board Game the diner produces either two (doubled with Agility training) or one (doubled with Luck training) food. The diner will randomly play Nuka-World theme song with the Nuka-World themed patch 1.7.

The diner is the only food production facility to which faction-specific themes can be applied.The diner was updated with a Halloween themed patch 1.2.Being the Tier I room for food production, the diner becomes obsolete once the Garden is unlocked at 70 dwellers, which subsequently becomes obsolete once the Nuka-Cola bottler is unlocked at 100 dwellers.Upgrade costs will be 25% cheaper for a double room and about 34% cheaper when upgrading a triple room vs upgrading 3 single rooms. The room will gain a +2 production bonus for each connected room. The dining room, like other rooms, gains a production bonus from being connected to another of the same type and level.
