Scoring + Timing
- Correct answer: +1 score and a new equation.
- Wrong answer: game over.
- If time runs out, the game auto-submits your current lane.
Arcade Mode
- Fixed challenge: 5 seconds and 4 answer lanes for every player.
- Level up: the operation mix and levels change every 3 questions.
- Unlocks: Subtraction begins at question 10, Multiplication at 25, and Division at 40.
- Late game: negatives and decimals can appear through normal randomness from question 70.
- Leaderboard: only Arcade scores can enter the public Top 100.
Custom Game
- Operations: enable any combination of +, -, ×, and ÷.
- Level (1-10): each operation has its own level. Higher means bigger numbers and trickier wrong answers.
- Timer and lanes: choose 2-10 seconds and 2-8 answer choices.
- Negatives: available when Subtraction level is 5+.
- Decimals: available when Division level is 5+. Decimal answers are rounded to 2 decimals.
- Personal practice: Custom Game keeps a local best for each setup and does not submit to the public leaderboard.
