Math Express

About this game

A math-learning take on classic train routing games — here, math isn't a popup quiz, it's how you control the railway!

Colorful trains race across the tracks toward matching stations, but every junction is locked. To flip a switch, clear a path, or stop a train before a collision, you must solve a quick math problem. Here, you don't practice math because you are forced to — you do it because the green express is speeding toward the wrong station!

KEY FEATURES
• Action-Driven Learning: Math directly controls the game. Solving a problem turns a switch, holds a train, or prevents a crash in real time while everything keeps rolling.
• Fully Adjustable Practice: Choose from ready-made presets for ages 6 to 11 (Grades 1–5) or set your own — addition, subtraction, multiplication, division, number ranges, and timers.
• Two Input Modes: Type the digits directly, or pick from six answers — for players who know the result but lose time on the keypad.
• Adaptive Challenge: As mental math gets easier with practice, the game scales up with more trains, longer trains, and faster speeds.
• Colorblind-Friendly: Station colors come from a palette designed to stay apart for every kind of color vision, and you can swap them for others in settings.

STREAKS, SPECIAL EVENTS & BADGES
Ten correct answers in a row unlock something extraordinary, and every further correct answer makes it more likely to appear.
• Rare locomotives, themed trains, and things that happen above the tracks rather than on them — the railway keeps a few surprises to itself.
• Achievement Badges: Collect a badge for every mystery you uncover, and watch your best scores ride past the main menu on a dedicated train.

PARENTS & SAFETY FIRST

WHY IT IS FREE
I made this game for my daughter, and it caught her more than I expected. So I am giving it to every other child who needs to practice. That is the whole reason there are no ads and nothing to buy.
