The built-in calculator handles complex scoring with full arithmetic, undo history, and a layout that adapts to your device orientation.
How It Works

- The calculator opens with the player’s current score
- Build an expression using numbers and operators
- Tap = to apply the result to the player’s score
Features
Section titled “Features”Arithmetic Operations
Section titled “Arithmetic Operations”The calculator supports four operations:
| Operator | Symbol | Example |
|---|---|---|
| Add | + | 42 + 8 → 50 |
| Subtract | − | 50 − 15 → 35 |
| Multiply | × | 6 × 7 → 42 |
| Divide | ÷ | 100 ÷ 4 → 25 |
Operator precedence is respected — multiplication and division evaluate before addition and subtraction. For example, 10 + 3 × 5 equals 25, not 65.
Undo & Backspace
Section titled “Undo & Backspace”- Undo — Step back through up to 50 levels of scoring history
- Backspace — Delete characters one at a time while building an expression
- AC (All Clear) — Reset the current expression
Decimal Support
Section titled “Decimal Support”Tap the decimal point for fractional scores. The display shows up to 8 digits.
Landscape Mode
Section titled “Landscape Mode”Rotate your device for an adapted layout:
| Orientation | Layout | Details |
|---|---|---|
| Portrait | 4×5 grid | Standard calculator layout |
| Landscape | 5×4 grid | Repositioned utility keys for wider screens |
Score Range
Section titled “Score Range”All scores are clamped to ±999,999. If a calculation would exceed this range, the result is clamped to the nearest limit.
- Use the calculator for multi-step scoring — enter
15 + 3 × 2in one expression instead of multiple taps - The calculator respects order of operations, so you can enter expressions naturally
- Swipe right on the display to backspace (in addition to the backspace button)

Does the calculator follow order of operations?
Section titled “Does the calculator follow order of operations?”Yes. Multiplication (×) and division (÷) are evaluated before addition (+) and subtraction (−), just like a standard calculator.
What happens if I divide by zero?
Section titled “What happens if I divide by zero?”The app handles this gracefully — division by zero returns 0 rather than crashing.
Can I enter negative numbers directly?
Section titled “Can I enter negative numbers directly?”Use the subtract operator. For example, to set a score to −10, enter 0 − 10 and tap =.
