Minuend

Five cards, one target, four operators. Nine handcrafted modes, a real on-device AI rival, and an exact-fraction engine. Every puzzle is solvable.

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.

PLAY YOUR WAY • Easy, Medium, and Hard difficulty. • A real AI opponent computed entirely on your device — no servers, no internet needed. • Unlimited hints, undo, and reset, so you're never truly stuck. • 52 Game Center achievements, per-mode leaderboards, and an in-app stats dashboard.
