Operand
Six numbers. One target. Combine them with + − × ÷ until they land. Operand is a one-minute daily ritual for people who miss the days of NYT's Digits — three fresh puzzles every morning, each one guaranteed solvable.
Free · No ads, no accounts, no tracking · Requires iOS 26 or later
Today looks something like this.
Reach the target using each number at most once. Every puzzle is generated on device and verified solvable before it ever reaches you.
A real Gold-tier puzzle from the generator. One road there starts with (100 + 50 + 10) × 5 — you take it from here.
Three tiers, every day
Bronze warms you up, Silver makes you think, Gold makes you sweat. New puzzles at midnight — no repeats, ever.
Streaks worth keeping
Solve daily, build the streak, and share a spoiler-free result card that shows how you fought — never the answer.
Practice without limits
An endless practice mode for long lines and short flights. Fully offline, forever.
Free. Actually free.
No ads, no account, no tracking, no paywall. Operand is fxjima's hello to the world.
Built for everyone
Full VoiceOver and Dynamic Type support, generous haptics, and no timers or fail states — undo as much as you like.
The same puzzle, everywhere
Everyone in the world gets the same three puzzles each day. Solve all of them for a Perfect Day, then compare without spoiling the answer.
First ashore.
Operand led the fxjima launch — and three puzzles are waiting for you today.
Free on iPhone. Requires iOS 26 or later.
