A pure-deduction logic puzzle with two interlocked grids — same "one solution, no guessing" promise as Queens, twice the depth. Free on iOS and Android.
If you love LinkedIn Queens for the satisfaction of deductive completion — every puzzle has one solution, found by reasoning, never trial-and-error — Twilight Grids extends that core into a richer mechanical space without losing any of the strictness.

Queens uses one grid where you place queens following colour-region, row, column, and adjacency constraints. Twilight Grids uses two grids — Day and Night — that share the same board positions but follow different rule families. The Day grid focuses on counting and balance (similar to Queens' constraint-satisfaction). The Night grid focuses on shapes and connections.
Cells in one grid can constrain the other through "bridges" — special tiles where placing a value on the Day side automatically determines the value on the Night side. Mirror bridges copy the value identically; inverter bridges flip light to dark and vice-versa. This means you reason across both grids simultaneously, not as separate puzzles.
Twilight tiles count toward rules on both Day and Night grids at once. They are the most constraint-heavy cells — solving one usually unlocks insights on multiple rules across both sides.
Where Queens uses one rule set across all puzzles (just varying the board size and colour regions), Twilight Grids progressively introduces 7 rule families across 7 game levels: First Light (balance + connectivity), Island World (island count), Split World (mirrors + splits), Gradient World (column bands), Tornado World (Minesweeper-style + border paths), Equilibrium (equal rows + dual paths), and Polarity (alternating parity). Each game level is a learnable puzzle dialect.
Like Queens, Twilight Grids has a Daily Puzzle with streak tracking. Unlike Queens, you can also play infinite procedural puzzles between dailies — useful for sharpening before the next day's challenge or grinding for 3-star mastery on a specific game level.
Twilight Grids is free to play with no LiveOps mechanics, no energy gates, no pay-to-win, no subscriptions. The optional one-time Infinity Unlock ($9.99) removes ads and unlocks unlimited hints — buy once, owned forever. Same player-respecting ethos as Queens, just delivered as a native mobile app you actually own.
Yes — Twilight Grids shares Queens' pure-deduction approach. Every puzzle has exactly one solution found through reasoning, never guessing. The key difference: Twilight Grids uses two interlinked grids (Day and Night) instead of one, with bridges and twilight tiles linking cells across them — adding mechanical depth while keeping the same no-guessing core.
Yes. Twilight Grids is free to download on iOS and Android, with infinite procedurally-generated puzzles included at no cost. An optional one-time Infinity Unlock ($9.99) removes ads and unlocks unlimited hints, but is not required to play.
Yes. Twilight Grids works completely offline — puzzles are generated on your device. Unlike LinkedIn Queens which requires the LinkedIn app and internet, Twilight Grids plays anywhere with no connection required.
Twilight Grids is closest to Tango mechanically (binary tiles, balance rules, no guessing), with the dual-grid extension adding shape and connection rules from the Night grid. It is distinct from Pinpoint (word association) and Crossclimb (word laddering) — Twilight Grids is purely visual-spatial logic, no language required.
Twilight Grids is available on the Apple App Store (iPhone, iPad, Apple Silicon Mac) and Google Play (Android). Both versions are free with the same gameplay and the same optional Infinity Unlock.
Twilight Grids sits in the broader pure-deduction puzzle family alongside LinkedIn Tango, nonograms / Picross, Sudoku, and Hashi. The dual-grid mechanic is unique to Twilight Grids.
