Minuend

Five cards. One number to hit. One satisfying click when it all snaps into place.

You're dealt five cards and a target. Combine all five — each used exactly once — with +, −, ×, and ÷ to land on the number exactly. Easy to learn in a minute. The kind of puzzle you'll still be turning over at the bus stop.

And here's the promise that makes it sing: every single deal is solvable by construction. No impossible hands, ever. A true exact-fraction engine means real fractions — never a rounding error, never a "that should have worked." When you solve it, you earned it, and the confetti, the spring, and the little sound all agree.

NINE MODES, NINE FEELS
• Classic — untimed and calm. Just you and the numbers.
• Daily — one shared puzzle every day, with a spoiler-free result to share.
• Blitz — fast, timed, limited lives. Pure adrenaline.
• Marathon — settle in for the long haul.
• Survivor — keep solving until your lives run out.
• vs Computer — race a real on-device AI rival (Easy/Medium/Hard) in a best-of series.
• Operation Lockout — one operator is disabled each round. Improvise.
• Target Hunt — same hand, how many different targets can you reach?
• Unrestricted — fractions and negatives unlocked. For when you want a fight.

Each one has its own goal, pressure, scoring, and finish — they genuinely play differently.
