■ AI Lotto Lab: New Recommended Numbers Every Week

An AI agent analyzes the latest Lotto draw data and generates Lab recommended numbers through 14 statistical filters and a 3-stage analysis pipeline.

Various criteria are applied step-by-step, including appearance frequency, non-appearance intervals, Bayesian analysis, interval distribution, odd/even ratios, sum ranges, consecutive numbers, and number flow.

Conveniently check and save the Lotto Lab recommended numbers that are updated weekly.

■ AI Number Generator: Automatic, Semi-automatic, and Manual Number Generation

You can generate Lotto numbers anytime, anywhere, in your preferred way. • Automatic Generation: Generates numbers using statistical filters or random methods
• Semi-Automatic Generation: Fix your desired numbers and auto-complete the rest
• Manual Generation: Create your own unique number set by directly selecting numbers from 1 to 45

Generated numbers can be saved in the app and used immediately via QR purchase slips.

■ AI Coach: From Questions to Number Generation in One Go

If you find Lotto analysis and number selection difficult, feel free to ask the AI ​​Coach.

You can make requests as if having a conversation, ranging from analyzing recent winning numbers and statistics by number to including/excluding conditions and generating multiple number combinations.

“Analyze the recent winning numbers,” “Give me 5 numbers including 7 and 13,” “Recommend numbers excluding those in the 20s.”

The AI ​​Coach understands even complex conditions and provides appropriate analysis and number combinations.

■ QR Verification: Quickly Check Lotto Winning Results

You can quickly and easily check your winning results by scanning the QR code on your purchased Lotto ticket.

Check your results with a single QR scan, without the need to manually enter numbers or compare them directly with the winning numbers.

■ QR Purchase Slip: No more inconvenience of writing numbers on paper

Converts saved Lotto numbers into QR Purchase Slips that can be used at retailer terminals.

• Select 1 to 5 games from saved numbers
