Balatro University Explains “naneinf” And How To Reach It

How do you reach an impossible score, so high that the counting system malfunctions and vomits up gibberish?

Everyone’s hooked on Balatro, the deck builder where the deck you build is made, not of nonsense cards with wizards on them, but basic types like Aces and Jacks. You start with a deck of 52 cards and try to make an increasingly valuable set of poker hands, but you can get Jokers that change the rules, Tarot cards that let you replace or remove cards from your deck, and can outright buy new cards to put in. Buy you can also mod your cards to be worth more, or multiply your score. You can advance your hands so they’re more valuable, and make secret hands like Five of a Kind.

The ultimate goal of Balatro is to reach 100,000 chips in one round, a goal that seems impossible when the first round sees you struggling to make 300. But 100,000 isn’t the end, it keeps scaling past that in its “Endless Mode” where Ante goal requirements can increase by a factor of 20 or more.

But Endless Mode has an end. Balatro uses Lua’s math routines to handle its goal and chip counters, and if either gets too high it loses track, throws up its hands and calls it “naneinf,” a value that always compares false, and so is useless to get and can’t be reached. This score is so big that written out entirely it’d have over 308 digits.

The channel Balatro University covers many aspects of the game, and they have a new 28-minute video where they explain what the word means (it’s “nan e inf,” or “Not a Number raised to the power of 10 times Infinity”) and the six specific ways to reach it. I’m afraid that people who aren’t already soaked in the details of the game might not get much out of it, it’s made for addicts and uses game terms without explaining them, but it might be interesting to visit that world for a bit, and let the weirdness wash over you.
