Instead of predictions or personal picks, it lets you see every combination that matches your filter criteria as concrete numbers, and compare them against historical draw frequencies. Work directly with the numbers. Set your own criteria, enumerate combination samples, inspect per-number frequencies across past draws, and save filter presets — a study and reference utility for probability statistics. ■ Made for you if... · You want to analyze lottery draw data yourself · You want to visualize probability, combinatorics and the possibility space · You want a combination counter that tells you how many combos match a filter · You want per-number frequency across recent draws in one clear view ■ A typical study flow · Open "Algorithm Filter" from home · Set odd/even 3:3, low/high 3:3, sum 100–175, consecutive pairs max 2 · Watch the matching combination count update instantly as a counter · Tap "View Combinations" to scroll the actual number list · Open "Report" to compare your filter against recent draws as coverage stats · Save as a preset and enable a draw-day reminder ■ Filter types · Odd/even · low/high · sum range · last-digit sum · column sum · Consecutive numbers (pair 1–7) · number spacing · number repeat · Missing draws · AC value · pair distribution · division rank · Include/exclude sets · number range ■ Features · Combination sample enumeration — actual combinations matching your criteria, with total count · AI Statistical Combination Samples (Premium) — advanced algorithm generates study-oriented samples instantly · Historical draw analysis report — how often your filter would have covered past draw numbers, as clear statistics · User opinion aggregate community — browse aggregated opinion statistics for reference · Past results & algorithm reference — filter settings stored alongside verified past results · Draw-day reminder — informational notice the evening before and afternoon of each draw · History management — saved combination samples auto-archived, results viewable in one place · Data visualization — per-number frequency charts, trend graphs, heat maps · 16 languages, auto-detected from device settings Supported lotteries (statistical scope only — no ticket handling): Mega Millions, Powerball (USA), EuroMillions, EuroJackpot (Europe), UK Lotto, Lotto 6/45 (Korea), Loto 6 / Mini Loto / Loto 7 (Japan), Lotto 6/49 & Lotto Max (Canada), Saturday Lotto, Weekday Windfall, Set for Life, Powerball, Oz Lotto (Australia), Mark Six (Hong Kong), Toto (Singapore), Taiwan Lotto & Daily Cash 539, Vietnam games, PCSO 6/42–6/58 (Philippines), Sports Toto Malaysia. ■ Data · Privacy · Free · Historical draws aggregated server-side from official operator sources, refreshed daily · Every statistical study feature works without an account (guest mode) · Saved settings and history live on-device by default (cloud sync only when signed in) · Sign in with Apple / Google is optional — receipt validation and cross-device sync only ■ Ad Removal (optional subscription) Every statistical study feature is free (with ads).
