With this app, you can create sequences of random numbers by yourself. Great to use when you need to generate random numbers. Basically, each ball is bouncing around, collide with other balls and walls along the way, and finally some of the balls will reach 'target points' and they will serve as your result balls. There're a bunch of different physics-based ball machines in this app, they use accelerometer datas from your device to simulate real world movements and collisions. Each ball machine is well designed with the thought of adding real world random data into the system. With all of these, they gives you ball combinations, that are high quality in terms of randomness. Shake and rotate your phone, let those balls collide and mix, put the phone up-right and you will have sequence of random balls. Each ball machines are slightly different to operate. # Each ball machine can generate up to 20 random balls in up to 100 balls. # You can group as many as 10 ball machines together # The final results are only for your references.

Adjust the range and tap. Need a binary yes-or-no decision? Range 1 to 2. The whole app is built around that one workflow: choose your range, tap, get a number. Whether you call it a random number generator, a random picker, an RNG, a randomizer, or a number chooser — this is what you came for. No ads cluttering the screen, no in-app purchases blocking features, no account required. Use cases people love it for: • Raffle and giveaway draws — pick a winner from your entry list by number • Lottery numbers — generate Powerball, Mega Millions, EuroMillions style picks • Decision making — set range to 1-2 for yes/no, 1-3 for rock/paper/scissors-style choices • Classroom number picker — random student selection from a roster size • Sports — pick a starting position, set order, or random tiebreaker • Tabletop and party games — generate a number when you don't have dice handy • Guessing games — set a range and have someone guess your number • Naming numbered options — pick a meal, a movie, a chore from a numbered list • Statistics and sampling — pick random samples from a numbered population • Programming and testing — quick PRNG output for prototypes and demos Why pick Lucky Random Number Generator over the dozens of clones? • One-tap simplicity — most generators bury the action behind menus • True custom range — not just dice (1-6) or lottery (1-49); set any min/max • Lightweight — minimal storage and instant launch • Honest — no fake "wheel of names" or "dice roller" UIs we don't have. Just numbers. • Trusted — part of the Lucky family of utility apps with 100k+ collective installs Common questions: Q: Is this truly random? A: It uses a high-quality pseudo-random number generator (PRNG) seeded from the system. Sufficient for raffles, decisions, games, and casual use. For cryptographic randomness, use a dedicated CSPRNG library — not any consumer app. Q: Does it remember my last range? A: Yes. Set your min/max once and the app remembers it next time you open it. Q: Can I get the same number twice? A: Each tap is independent. Two taps can produce the same number — that's how randomness works. If you need unique picks (a draw without replacement), generate enough numbers and discard duplicates. Q: Will I see ads? A: A minimal banner only. No video ads, no interruptions during use. Q: Privacy? A: We don't collect personal data. The app generates numbers locally on your device — no internet required.
