Numina: Mental Math Games

Nine math games: addition, multiplication, memory and logic. Free, offline, no account — and never an ad in the middle of a game.

Numina turns mental arithmetic into a daily habit. Nine fast, beautifully designed brain games — no account, no clutter, no tutorial to sit through. Open the app and you are playing in seconds.

Whether you have 60 seconds in a queue or 10 minutes on the sofa, there is a game here that fits.

NINE GAMES, NINE SKILLS

• Cascade — Speed & fluency. Equations fall like raindrops; type the answer before they hit the water. The same answer pops every matching drop, and solving the sun clears the screen. Miss three and it's over. How fast can your brain go?

• Libra — Comparison & reasoning. Two expressions, one question: which side is bigger? Tap the larger one — or EQUAL if they match — against the clock. Build a streak to raise your multiplier and earn bonus time.

• Equato — Reasoning & planning. Combine number tiles with +, −, × and ÷ to reach the target. Fewer tiles means more points. Play the timed Challenge, or relax in Zen mode with no clock at all.

• Echo — Memory & recall. A chain of operations flashes one step at a time, then vanishes. Hold it in your head, do the maths, type the result. Longer chains score more. The one game that trains working memory.

• Prisma — Patterns & logic. Read a number sequence and pick what comes next. Sums, products, growing steps, alternating jumps — the rule changes every round, and there is always exactly one right answer.

• Nexus — Paths & planning. Link neighbouring cells across a grid so the running total lands exactly on the target. Longer paths score more, and every grid is guaranteed solvable.

• Lacuna — Inverse thinking & number sense. An equation appears with one piece missing — a number, or sometimes the sign itself. Fill the gap before the timer runs out. Every gap has exactly one right answer, guaranteed.

• Tessera — Quiet thinking, no clock. A grid of numbers: merge two neighbouring tiles with an operation, then another, until a single tile holds the target. No timer, no losing, unlimited undo — take all the time you want. Every grid is guaranteed solvable.

• Indicia — Deduction, no clock. Identical tokens, one weighs wrong, and a balance scale. Load the pans, read the tilt, name the odd one. Nothing is decided in advance: guessing never works, reasoning always does.
