Factor Fields
Factor Fields is a multiplication and factors game that plays in the browser on phones, tablets and computers, for one player.
Plant exactly the number of seedlings a farmer orders, in equal rows, and find every field that works. Each new way of making the number from rows is a factor pair that goes on its page of a 144-page number book. A prime number allows only one strip, and saying you have found them all proves it.
How to play
- Drag on the plot to mark rows of seedlings, then let go to plant
- Each new way to fill the order exactly is a new field for the number book
- Every field found? Tap All found. A prime has only its one-row strip
The game shows these steps as you play, the first time.
Controls
- Drag on the plot and let go to plant, or use the steppers and Plant
- Arrows change rows and seedlings, type digits, X switches box, Enter plants, F says all found
Tips
- Count up from one row: try 1, 2, 3 and so on, and stop once the rows outnumber the seedlings in each row.
- Three rows of eight and eight rows of three are the same field turned round, so each pair only counts once.
- Saying all found too early counts as a slip, and an order with no slips earns three stars, so check every row count first.
How do I plant a long strip like 1 by 36?
The plot holds 12 rows of 24, so drag for anything that fits and use the minus and plus steppers or type the numbers for longer fields. A field that is too long is still planted and checked, and is drawn smaller on the plot.
What are the badges in the number book?
A page is ticked once every field for that number is found and you say all found. Primes, which only have the one-row strip, get a P seal, and square numbers such as 36 show a square mark beside their middle field.
