Make Ten

Point your camera at a carriage number and see if you can make 10!

Make Ten turns your daily commute into a puzzle. Inspired by the Sydney Trains Make Ten Challenge, the goal is simple: every train carriage has a unique four-digit number, and using all four of those digits together with basic arithmetic, you try to make the number 10.

Point your camera at a carriage number and Make Ten reads the digits automatically, or type the four digits in yourself. Instantly see whether a solution exists, and reveal the full working equation whenever you're ready.

Features:

• Camera scanning — point at a carriage number plate and the digits are detected automatically, no typing required
• Manual entry — enter any 4-digit code by hand
• Instant solvability check — know right away if the code can be made into 10
• Spoiler Guard — hide the solution until you choose to reveal it, so you can try solving it yourself first
• Optional exponentials — allow powers (^) as well as +, −, ×, ÷ for trickier codes
• Practice mode — generate random solvable codes to sharpen your mental arithmetic anywhere, even without a train in sight

Whether you're killing time on the platform or just enjoy a quick daily arithmetic challenge, Make Ten is a lightweight, offline-friendly way to keep your mental maths sharp.
