| One-Tap Moves |
When on, the higher die will be displayed on the left. Tapping on a checker will move it using the left die if possible. If not possible, it will move using the right die. Tapping on the dice will swap the positions of the left and right dice. |
| Autoplay Forced Moves |
When on, the computer will automatically move for the player when there is only one possible move. |
| Automatic Bearoff |
When on, the computer will automatically move for the player in a bearoff situation without opposition. When set on Greedy, it will choose the move that bears off as many checkers as possible, as long as there is only one such move. If there are multiple moves of this type, then Greedy mode will not activate. Note: the Greedy move may not always be optimal. When set on Best Move, the computer will choose the best move according to its AI. This is equivalent to pressing Hint. |
| Checker Speed |
Select the checker movement speed. |
| Auto Finish Speed |
Select the speed at which Auto Finish plays. |
| Move Tutor Threshold |
When on, the Hint button will glow blue when you make a bad move. The threshold level that you select will determine what is considered a bad move. |
| Cube Tutor Mode |
When on, the doubling cube will glow blue when you should double. Also, when your opponent doubles you, the Accept or Resign button will glow blue to tell you which action to take. When off, you can tap the Hint button during a cube decision to see the correct action to take. |
| Confirm Doubles |
When on, you will be asked to confirm when you double. This is used to prevent accidental doubling. |
| Confirm Exit |
When on, you will be asked to confirm when you exit the app using the Back button. |
| Sound |
Turn sound effects on or off. |
| Manual Rolls |
When on, you can roll real dice and enter the rolls into the game. This option is used to prove that the computer does not cheat. |
| Random Number Generator (RNG) |
| RNG Seed |
Select the random number generator seed that determines the list of dice rolls for the current session. Setting the seed to a particular value will reproduce the same list of dice rolls. This seed can be used to print out and analyze upcoming dice rolls.

| Next Roll Number |
Select the next roll number to use, ranging from 0-99999. While the seed determines the list of dice rolls, the next roll number determines which roll in the list will be used next in the game. You can set this along with the seed in order to replay games. For example, if you start a game on roll 40, then after the game, you can set the roll number back to 40 in order to play a new game with the same dice rolls. |
| Save RNG Seed |
When on, the RNG Seed and Next Roll Number will be saved across sessions. When off, the RNG Seed and Next Roll Number will be reset each time you restart the app. Note: The saved roll number is limited to 99,999 rolls. If the limit is reached, the RNG Seed and Next Roll Number will be reset the next time you restart the app. |
| Swap Opening Rolls |
When on, the dice for the opening roll will be swapped. This will result in the opposite side winning the opening roll, and thus, all subsequent rolls in the game will also be swapped. For example, if the opening roll were 6-1, normally the player would move first because the player uses the first die (6), and the computer uses the second die (1). If the Swap Opening Rolls option is turned on, the opening roll would become 1-6, and the computer would win the opening roll. This option can be used in conjunction with the previous two options to replay a game where each side receives the other side's dice rolls. |
