RustPike

RustPike is a vertical timed mental arithmetic challenge mobile game that turns addition and subtraction into a fast-paced quiz sprint. Players have 90 seconds to quickly read each question and tap the correct answer from diamond-shaped options. Correct answers build combos and move to the next question; wrong answers deduct two seconds and briefly highlight the correct answer, forcing you to stay calm under pressure. You can pause to adjust your rhythm during the round, and after the round ends, your score and historical high score are recorded. Simple controls, yet requiring a balance between speed, accuracy, and time management, perfect for challenging higher combos in short sessions.
