Whenever I play EarthBound, I always avoid getting Lucky Sandwiches since they’re pretty meh and I don’t like gambling with limited inventory space. But I’ve never really known how these Lucky Sandwiches actually work – all I knew was that they have random effects.
A few years ago some skilled hackers dug into the ROM and found out a bunch of technical stuff, including how Lucky Sandwiches work. So here’s the deal with them:
When you buy a Lucky Sandwich (more precisely, immediately before the text “Lucky sandwich? Who is going to carry this?”), the game chooses from one of six Lucky Sandwich item entries to use. The recovery effect of a Lucky Sandwich is set in stone once bought, so it’s possible to stockpile certain types.
Determination Process:
Generate a random number 0-15. If less than 7, 60 HP sandwich.
Else generate a random number 0-8. If less than 4, 240 HP sandwich.
Else generate a random number 0-4. If less than 3, full HP sandwich.
Else generate a random number 0-1. If 0, 5 PP sandwich.
Else generate a random number 0-2. If nonzero, 20 PP sandwich.
Else full HP+PP sandwich.Probabilities:
- 60 HP: 44% (21/48)
- 240 HP: 25% (12/48)
- full HP: 19% (9/48)
- 5 PP: 6% (3/48)
- 20 PP: 4% (2/48)
- full HP+PP: 2% (1/48)
So there you go! It looks like over 50% of the time it gives a “meh” result, so I guess that’s why I never buy them. I feel like I’m in the minority though – does anyone actually buy them often?

Ha, looks like I’m not in the minority after all. I always assumed everyone else got them regularly.

I got so annoyed because they always gave me 5 PP, or if I’d be “lucky” (ha ha), 20 HP. So I gave up on those, too.

I rarely use food for healing purposes in games, so I’m not sure I ever actually bought a Lucky Sandwich.

I get them rarely, and only to use outside of battle at that. I think I got a good one once during the mall blackout, but aside from that, I don’t think they have ever pulled me out of trouble. I guess it’s another “useful useless item” along with the ruler and protractor.
Never bothered with them, but now that I think about it, you could probably test and stockpile the best sandwiches using the condiment trick–reset if it’s a bad one, and keep it if it’s a good one. Probably more trouble than it’s worth though at those odds, even at a fraction the price of Brain Food Lunches.
The only time I every actually try to obtain a lucky sandwich is during one those rare plays where I just want to buy/use everything. Otherwise, I’m with you Mato. I usually just ignore them.
Wow. I don’t think I’ve ever even heard of a Lucky Sandwich before! Then again, I rarely use food to recover health.
I’m recording my playthrough for my friend, and I’m still before Onett.
Didn’t use it that much myself but I suppose since it’s determined when one buy’s it with enough money and save points you could get a pocket full of max hp and max pp items. >:3
In RPGs I usually only use a few items, because I can never remember what the rest do! lol Especially in battle.
And I never bothered with the condiment system.
Yeah, I never bothered with condiments either. It was a cool idea, but it never seemed beneficial enough to sacrifice that much room in your inventory for it.
I used condiments sometimes just to see what works with what food, I used them with weaker foods to boost them up. I still think they’re worth it in those situations.
When ever I buy lucky sandwiches I get full recovery of hp pp or hp and pp!
I think I used to think that they impacted luck somehow? I don’t even know if I ate them at all… I couldn’t see the point. (Maybe I thought that, tried it out, and got a bad result?) I actually think they’re kind of cool, seeing the different chances. “A gamble in every bite!”
hmm i feel like a sandwich now…wish i could go buy a sandwich and try my luck
@Ace: I don’t always eat Lucky Sandwiches, but when I do, I always recovery full HP.
I always just buy the weirdest things in video games – the stuff nobody else does. It’s kinda fun.
I don’t recall — is it possible to find a Lucky Sandwich in a trash can or gift box? If so, it it always a specific type of Lucky Sandwich, or is there a random draw at some point?
