What is Number Line
A sharp, no-nonsense puzzle about putting numbers in their rightful spots. If you enjoy untangling logic, this one's for you.
How to Play
Read the clues that describe how numbers relate—like one being to the left of another or a fixed gap. Drag or click to place numbers on the line, using the clues to narrow down the arrangement until all are correct.
Tips for Playing
- Start with the most restrictive clues that mention exact positions or adjacencies.
- Cross off impossible spots for each number as you go.
- If stuck, pick a clue with two options and test one mentally.
- Keep a mental image of the line—left means smaller, right means larger.
- Re-read clues after placing a few numbers; new info often emerges.
