LottoLab: Lotto Number Picker

LottoLab is a statistics tool that draws numbers from the complete, real draw history of each game. ■ Five games in one app Powerball and Mega Millions (US), Lotto 6/45 (Korea), Loto 6 and Loto 7 (Japan) — each with its own number matrix and prize-tier rules. ■ Four generation methods - Frequency weighted: drawn in proportion to all-time hit counts - Hot/cold trend: weighted by the last N draws (hot, balanced, or cold) - Pattern filter: odd/even ratio, zone spread, and sum range constraints - ML prediction (experimental): blended frequency and recency score ■ Automatic result checking Saved picks are graded automatically once the draw results arrive — no manual comparison. ■ Per-number statistics Hit frequency and current dry spell for every number, across all draws or the last 10/20/50. ■ Offline first · no data collected The full draw history ships inside the app, so it works with no connection. There is no sign-in, no tracking, and no analytics — saved picks stay on your device. Note: LottoLab is a number-generation and record-keeping tool. It does not sell tickets, take payments, or pay out prizes. Statistical generation is for reference only and does not improve your odds of winning. LottoLab is an unofficial app, is not affiliated with any lottery operator, and officially published results are the only legal basis for a claim.
