Lattice: Number Logic
Cross math, beautifully.
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Cross math is only the beginning.
Lattice turns number logic into calm, tactile puzzles. Place every number so each connected equation becomes true. Start with familiar cross-math boards, then explore waves, orbits, dials, a pyramid, a rotating cube, and other structures.
WHY PLAY LATTICE?
• 1,000+ engine-verified puzzles across 11 worlds
• Five difficulty levels, from Easy to Master
• A fresh Daily puzzle and an Endless mode
• Optional hints that teach the next useful step
• Calm themes, satisfying sound, and thoughtful haptics
• No account, energy timer, or subscription
• Core puzzles work offline after installation
PLAY FREE OR UNLOCK COMPLETE
Play for free with ads. When eligible, a rewarded ad can grant a hint. Lattice Complete is one optional purchase that removes ads and unlocks the complete experience—there is no recurring subscription.
BUILT FOR REAL PUZZLE SOLVERS
Every included puzzle is verified to have one solution. Difficulty comes from the deduction required, not from guessing. Choose your level and learn each new shape at your own pace. Daily verification and the optional Endless leaderboard require a network connection.

New in 1.0.4:
• Endless now offers one optional second chance when the board overflows. Watch a rewarded ad to remove the oldest row and continue the same run.
• Continued runs are clearly marked unranked and are not submitted to the leaderboard.
• Stability and localization improvements.
