About Boxcar Sequence: Number Train Yard
All aboard the pattern express! Each train rolls in with one boxcar missing its number. Work out the rule — steps, doubling, squares, Fibonacci-style sums, primes and more — and couple the right wagon before departure time. A wrong pick reveals the rule so you learn as you go. 40 levels across Easy, Medium and Hard, with touch, mouse and keyboard controls and sound you can mute.
How to Play Boxcar Sequence: Number Train Yard
- Goal: complete every train.
- Read the sequence on the wagons, then tap the answer wagon that replaces the ? (or press 1-4) before the clock runs out.
- A wrong wagon or a timeout costs a heart (three hearts) and shows the rule.
- 40 yards in three difficulties, from simple addition patterns to interleaved sequences.
