Paciolino

What is Paciolino?

Paciolino is a daily logic puzzle set in a ledger, where each number must be marked as either a debit or a credit. The goal is to make every row and column balance. Each puzzle has exactly one solution and is designed to be solved through pure logic, with no guessing required.

A daily puzzle that actually honors its 'one solution, no guessing' promise is rare, and Paciolino's logic stays tight enough that the only thing you can blame when it stings is your own reasoning.

With a leaderboard, stats page, and a growing archive to mine, Paciolino hands you the numbers to track your solving times and streaks — and the daily format keeps the sample size climbing.

Between the full archive, the stats page, and leagues marked 'coming soon,' Paciolino is clearly built for completionists who want to clear every ledger and chase every badge the game will eventually

Paciolino works like a clean, minimal loop — one sharp hook per day with no filler, and the archive is the deep-cut B-side collection you'll actually want to revisit.

How to play Paciolino

You are shown a grid of numbers and must assign each one a debit or credit classification. Every row and every column must balance, meaning all the chosen values have to work together in a single consistent arrangement. Work through the grid logically to find the unique solution.

Tips & strategy

• Start with rows or columns that have the fewest numbers, since they tend to give the clearest constraints.
• Remember that every puzzle has exactly one logical solution; if you get stuck, re-examine your earlier choices instead of guessing.
• Consider each number’s role in both its row and its column before making a final decision.
• Use elimination: rule out classifications that would make a row or column impossible to balance.
• Check your work as you go, because a small error can make the rest of the puzzle unsolvable.
