Factorscape

Multiply and divide your token by primes to land it exactly on the target, capturing rivals you share a factor with along the way.

How to play

Your token sits on a number track shown on a logarithmic scale. Multiply or divide by the primes 2, 3, 5 and 7 to change its value, aiming to land precisely on the target number. You can only divide by a prime that currently divides your position; capture rival markers by sharing a prime factor with them.

• Press a prime button to multiply or divide your current value
• Division is only legal when the prime actually divides your position
• Land exactly on the target's prime factorization to win
• Capture rivals en route and finish under par on moves for a higher score

Game modes

• Difficulty: Easy, Medium or Hard
• Daily: a fixed level shared each day
• Practice: fresh randomized levels

Controls

• Desktop: click the multiply and divide buttons for each prime; Undo and Hint are available
• Phone & tablet: tap the prime operation buttons (mouse or touch only)

Tips & strategy

• Compare your factorization to the target's and add or remove exactly the primes that differ
• Route through rivals that share a factor to capture them without wasting moves off the shortest path

What you'll learn

Factorscape is built on prime factorization, turning the building blocks of numbers into a landscape to navigate.

• Skills: prime factorization, number theory, factors and multiples
• Best for: roughly grades 6–11 (ages 11–16)
• For parents & teachers: prime factorization as building blocks.
