Random Number Generator, Dice Roller & Coin Flip Bring nine random tools together in one app. Generate numbers, roll dice, flip a coin, draw a playing card or explore other random results. RANDOM NUMBERS WITH YOUR SETTINGS Set your minimum and maximum, choose a quantity, then generate. Allow duplicates or request unique numbers, exclude specified values, sort the results and display their sum. Use numbered results for classroom activities, games or a numbered raffle. Input values can reach 999,999,999, and the quantity limit is 9,999. The available range and exclusions can further limit the number of unique results. DICE ROLLER Choose between one and six dice. Select dice with 2, 4, 6, 8, 10 or 12 sides, then roll to see their individual values and total. Use the available combinations for board games, classroom activities and other games that need random dice results. COIN FLIP Tap to flip the animated coin and see heads or tails. Use it when deciding between two options. Each flip produces another random result, so outcomes can repeat. MORE RANDOM TOOLS Draw a random playing card, generate a letter from A to Z, or choose a rock-paper-scissors throw. Generate colors with hexadecimal and RGB values, create random dates and times between 2000 and 2040, or get a yes/no answer. Letters, cards and other independently generated results can repeat. COPY AND EXPORT Copy generated results for use elsewhere. Export features are subject to the app’s access controls. Random-number exports include CSV and an Excel-compatible spreadsheet format. Localized labels help explain the results while preserving the underlying values. PREMIUM AND ACCESS The app includes free-use limits and Premium access.
