Chains

Six numbers. One target. Can you build the chain?

Chains is a daily number puzzle with a simple rule: combine six numbers using add, subtract, multiply, and divide until you hit the target exactly. Each move chains two numbers into one — plan the whole path, or feel your way there.

Three fresh puzzles arrive every day — Easy, Tricky, and Expert — so the morning ritual takes two minutes or twenty, your choice.
