Quiet, fair, and beautiful.
Cross-math, the way it should feel.
Fill the grid so every equation is true. No guessing — ever. Our engine proves each puzzle has exactly one solution and grades it by how deep the deduction goes, not how big the board is. 1,000+ machine-verified puzzles across the campaign and Daily rotation.
Deduction, never a dice roll.
Every board is a closed argument. Each number you place is forced by the ones around it — follow the logic and the grid resolves itself. We generate each puzzle under strict design rules, then let the engine certify it before it ever reaches you.
Every screen is a different way
to think in numbers.
Nine-plus distinct mechanics, all machine-verified. Swipe through a few of them.
1,000+ puzzles, each proven to have one answer.
This is the heart of Lattice. Forged tiles anchor the grid; the rest you deduce, one certain step at a time. Every board is machine-verified before it ships — if there are two ways to solve it, it never reaches you.
Rotate the cube. Solve every face.
One of two true 3D worlds. Spin a cube in your hand and the equations wrap around its edges — the same fair, single-solution logic, now with a sense of space you can actually feel.
Deduce the hidden operators.
Some grids hand you the numbers but hide the signs. Is it times or minus? The math tells you — there's always exactly one arrangement that makes every line true, and finding it is the whole, quiet thrill.
Rings of logic, one quiet hub.
Numbers circle a shared center, and every ring has to agree with it at once. It looks like a constellation and solves like a proof — a calm, satisfying loop of cause and effect.
Both sides, one truth.
Two halves of an equation, meeting in the middle. Tip one and the other has to answer. It's cross-math as a quiet act of equilibrium — nothing settles until everything does.
Twist the rings into truth.
Drag a ring and it clicks between positions; every spoke has to balance, inner against outer. Align them all at once and the dial resolves with a click you can almost hear.
The details you only notice
when they're missing.
Fair puzzles, honest scores, and a game that respects your time and your privacy.
1,000+ proven puzzles
Every board is machine-verified to have exactly one solution before it ever reaches you. No dead ends, no ambiguity.
12 playable shapes, 9+ mechanics
Frozen slots, forged tiles, mystery operators, orbits, dials — even a real 3D cube and pyramid. The grid keeps reinventing itself.
Hints that teach
Stuck? "Explain" replays the engine's own deduction, step by step — so you learn the move instead of just unblocking it.
