Sum Trail

Sum Trail is a quick math quiz built around one simple goal: solve as many equations as you can before time runs out.

Tap Play and jump straight into a 60-second round. Each question shows an equation with four answer choices — pick the correct one to earn points and keep going. A wrong answer costs one life. You start with 3 lives; lose them all and the run ends.

How it works

Addition & subtraction in early levels (numbers up to 20)
Multiplication from level 3 (factors up to 12)
Mixed questions at higher levels for a tougher challenge
Score grows with each correct answer; higher levels give more points per answer
Level up after 5 correct answers in a row
Timer counts down from 60 seconds — survive with lives left to win the round
After each run The results screen shows your final score, level reached, accuracy (correct vs total questions), time left, and your best score across sessions. Recent Runs lists your last 5 completed games on this device so you can compare your progress over time.
