About this app

Lottoria645 is an integrated lottery analysis assistant app based on data from the Korea Donghang Lottery (formerly Nanum Lotto) Lotto 6/45. It provides features such as looking up winning numbers, predicting excluded numbers, analyzing winning number trends, AI-based recommendations, generating conditional combinations, managing your numbers, QR/OCR recognition, searching for retailers, and PC/Tablet web browser analysis.

Going beyond a simple lottery number generator, it analyzes historical winning number data under various conditions and helps users create number combinations tailored to their desired criteria.

In particular, the biggest differentiator of Lottoria645 is its PC/Tablet web browser analysis feature for Master-tier users.

On the PC, you can broadly view various data such as winning number trends, inclusion/exclusion recommendations, conditional analysis, and ticket patterns, while on the mobile phone, you can simultaneously generate, save, recognize QR codes, and manage purchased numbers.
