Seeing a score in the billions feels incredible until you discover that some Balatro players have pushed past every number the game can display, landing on what the community calls NANEINF: a score so massive the engine simply outputs infinity. If you've been staring at your 5-billion-point run wondering how that's even possible, this guide breaks down exactly what's happening and how you can replicate it.
NANEINF is shorthand for a score that exceeds the limits of standard floating-point arithmetic. The IEEE-754 standard defines log10(Infinity) as Infinity itself, which rounds down to Infinity and displays as inf in-game. The final step in score display tries to extract a mantissa from that value, producing NaN (Not a Number) as a prefix—hence NANEINF. You've scored so many points that the game's math library has given up trying to express the result as a real number.

The engine behind every NANEINF run is xMult stacking. Unlike flat +Mult additions, xMult values multiply your existing multiplier rather than adding to it, producing exponential rather than linear growth. Stack enough of them and you cross the threshold into infinity.
The most reliable path to infinite scoring centers on two jokers working together:
With multiple copies of Baron and Mime in play (achieved through joker-copying effects), each King in your hand triggers xMult several times per scoring event. Scale your hand size upward using consumables or jokers that increase cards held, and every additional King multiplies the effect further.

Hand size is the third lever in this setup. More cards held means more Kings visible, which means more Baron triggers per hand played. Players typically push hand size to 10 or higher before attempting the final scoring hand. Jokers and spectral cards that increase hand size are high-priority pickups in any NANEINF-focused run.
Community records show single-hand scores reaching 5.66 billion before the NANEINF threshold is crossed. Once the score hits infinity, the display breaks and the run effectively has no scoring ceiling. The achievement for reaching NANEINF is a recognized milestone, with players posting screenshots as proof.
| Score Range | What It Means | Difficulty to Achieve |
|---|---|---|
| Under 1 billion | Strong standard run | Moderate |
| 1-5 billion | Elite scaling build | Hard |
| 5.66 billion (recorded) | Near-NANEINF threshold | Very Hard |
| NANEINF (infinity) | Floating-point overflow | Extreme |
Scaling jokers are almost universally the strongest long-term investments in Balatro. Look for jokers that grow passively over rounds rather than those that offer a fixed bonus. This foundation makes the late-game xMult explosion possible because your base numbers are already elevated.
Joker order matters enormously. Flat +Mult additions should appear before xMult jokers in your joker slots so the multiplied value is as large as possible when the xMult jokers fire. Placing Baron and Mime at the end of your joker row ensures they multiply the fully accumulated +Mult total.
This is the hardest part of any NANEINF run. You need joker-copying effects, which are rare. Keep an eye on spectral cards and specific shop offerings that can duplicate jokers. Each additional Baron or Mime copy accelerates your xMult growth toward the overflow threshold.
Once Baron and Mime are in place, shift focus to filling your deck with Kings and increasing your hand size. Use tarot cards to remove low-value cards and improve deck consistency. A hand of 10 cards where 5 or more are Kings will generate xMult values that compound into the billions within a single scoring event.

Hand selection still matters even in a NANEINF build. Pairs are a reliable and consistent choice for triggering held-card effects repeatedly. Full House, despite sounding powerful, is widely considered one of the weakest builds in the game because it demands too many specific cards and delivers inconsistent results compared to simpler hand types.
Reaching NANEINF requires surviving long enough to assemble the pieces, which means your economy needs to be solid throughout.
One of the most important mechanical distinctions in Balatro is the difference between +Mult and xMult. Many newer players treat them as equivalent, but the math is completely different:
If your multiplier is currently 100 and you add +50 Mult, you reach 150. If you instead apply x2 Mult, you reach 200. Chain three x2 Mult sources and you reach 800. This exponential behavior is why Baron and Mime can push scores into infinity while flat +Mult jokers, no matter how many you stack, will never get close to NANEINF on their own.
The biggest misconception is that NANEINF requires luck above everything else. The setup is specific but learnable. The key insights that separate players who reach it from those who don't:

Reaching NANEINF in Balatro is one of the most satisfying achievements the game offers. The path there is consistent: build your economy early, acquire Baron and Mime copies, expand your hand size, fill your deck with Kings, and let exponential xMult do the rest. The scoring system literally can't keep up.
