### AI overview

The author searches for the least erratic Erratic deck in Balatro by examining every possible game seed. After finding Lua too slow for the 2.3 trillion-seed search, they optimize the Lua implementation and then port it to Rust, using all CPU cores to reach about 100 million seeds per minute. The article also explains a bug that can produce decks filled with the ten of spades.

### Source excerpt

My most recent "just for fun" project was to find the least erratic of the Erratic decks in Balatro (a poker-ish roguelike deckbuilder game). Before each game, you pick a deck that has a special power. The Erratic deck completely randomizes the ranks/suits of the cards
