*************** Descriptions of the Free Features ***************
Here's a brief description of Natural 20 Lite’s screens, which are available free!
~ Quick Roll
Simply pick your dice, and you have an instant result. Ideal for Dungeons & Dragons, Quick Roll offers the following eight dice; D2, D4, D6, D8, D10, D12, D20 and D100.
~ Multiple Dice
In multiple dice mode you can mix your dice together as you please. Tap each row to add five at a time, or use the plus or minus to add or remove one. You can roll or remove individual dice again. Stats, such as average and the sum, are displayed for each roll saving you counting on screen.
~ Teachers Die
Handy for the classroom, this die will be helpful for Maths and English. You can use it to randomly pick letters, numbers and mathematical operators.
~ Roll History
Natural 20 keeps track of all your rolls, so you can prove you actually rolled that 20! The dice stored in your history can be easily re-rolled and filtered. You can move the dice around the screen, and it will remember your order.
~ Distribution
Distribution allows you to create probability distribution plots for specified dice. These will show you the percentage chance of rolling a particular face value, and you can compare actual rolls against theoretical results. However, large numbers of dice can take a long time to calculate for theoretical plots.
*************** Features unlocked with an in-App Purchase ***************
For $0.99 USD you can permanently unlock the following screens, with a single in-app purchase.
~ Calculator
Great for large numbers of dice, or combinations with a modifier.
~ Custom Die
Custom Die lets you choose the sides of the dice, by separating them with commas. Natural 20 will pick a single item, or order them randomly into a list.
~ Colour Die
This will give you a random colour, just run your finger across the screen like a paintbrush. Displayed on the screen will be some basic information. For example the colour’s hex number, HSB and RGB values.
~ Direction Die
This will point you in a totally random direction with each spin. Swipe the screen to spin it, however you can only influence which way it spins, not the outcome!
~ Success Die
Repeatedly rolls D6’s, discarding when they fail to meet a certain value. The total successes are displayed.
~ Word Die
Keep collections of words, to randomise at a touch. Ideal for selecting locations and enemies randomly. You can even randomise your words as a whole list.
~ My Dice
My Dice allows you to save your own collections of dice, along with a description and optional modifier. These can be easily searched through, and rolled from a single tap.
~ Dice Builder
Chose how many sides your dice have, and their colours!
*************** Random Number Generation ***************
Natural 20 Lite uses your devices built in randomiser (arc4random_uniform) to generate values. This has been tested with large numbers of dice, to ensure there is no bias present. In the full version, Natural 20 offers a screen called "Distribution". This allows you to test this yourself, with rolls of 100,000 dice at a time.
