RNGadget is the best way to generate random numbers on iOS! It offers a variety of basic and advanced modes to help you generate numbers in as many ways as I could think of. Basic Modes: - Numbers: Generate a single random number using only a minimum and maximum number. The simplest way to generate numbers. - Coins: Flip a series of coins! Flip up to 50 consecutive coins with fancy haptics. - Dice: Generate numbers using up to 9 standard 6-sided dice. - Cards: Generate numbers by drawing a hand of up to 7 cards. Optionally, you can display the point values of each card drawn, with the Ace being toggleable between 1 and 11 points. - Marbles: Generate up to 9 letters by rolling some marbles. (Kind of like when you play bingo.) Advanced Modes: - Dealer: Deal a deck of cards out to a set number of hands. All basic modes are also available in a smaller form (fewer coins, dice, cards, and marbles) on Apple Watch, for when you need to flip a coin or roll some dice in a pinch.
