PlaySlip is a clean, honest utility for lottery players. Generate number sets, keep the numbers you actually play, and look up what any number has really done — all from published draw results. LATEST RESULTS, FIRST THING Choose which games appear on your home screen and see the newest drawings the moment you open the app. Daily 3 and Daily 4 show midday and evening separately. Results refresh on their own, and you can pull down any time to check right now. NUMBER LOOKUP Type a three- or four-digit number and see its real history: how many times it has fallen straight, how many times boxed, when it last came in, the midday and evening split, and how long it has been since. Built on 16 years of official Michigan Lottery results — more than 24,000 drawings. You can also look up any date to see everything that fell that day. MY LINES (PET NUMBERS) Save the numbers you play, whether you generated them or looked them up. Tag each one with how you play it — Straight, Box, 2-Way, Wheel or 1-Off — and log every time you play it. DID I WIN? Check your saved lines against the latest published results. PlaySlip judges each line by the bet type you selected, because a Straight ticket doesn't pay when the digits fall out of order. It tells you exactly what your number did and points you to the official lottery to confirm anything. THREE WAYS TO PICK • Quick Pick — uniform random across the full range • Personal Seed — a repeatable set derived mathematically from a date and name you enter • Balanced — re-rolled for a mix of odd/even and low/high Every mode has identical odds. The modes are about how you like to choose, not about improving your chances. NUMBER STATS Hot and cold digits, overall and by position, plus longest droughts and frequency leaders — all computed from real published draw data, with the math shown plainly. GAMES COVERED Powerball, Mega Millions, Daily 3, Daily 4, Daily 5 (launching in Michigan August 28, 2026), Fantasy 5, Lotto 47 and Club Keno.
