Draw one line. Run the shift. Watch every parcel find its way. One-Line Factory is a compact logistics puzzle about planning one continuous conveyor from IN to OUT. Guide every parcel through its stations in order, then start the line and see whether your design can meet the quota before time runs out. MASTER 36 HANDCRAFTED BOARDS Six factory departments build on the rules one shift at a time. Route around blockers, obey one-way gates, balance limited belt tiles and tight corner budgets, use fast and slow cells, cross your own path with overpasses, and time shutters that open and close on their own rhythm. COMPLETE, THEN OPTIMIZE Solving a board is only the start. Rework your route to earn three independent stamps: - Completion โ deliver the full quota - Compact โ stay within the route target - Express โ beat the expert time CLOCK ON FOR ENDLESS SHIFT Unlock an ever-changing mode where each procedurally generated floor has a route to discover. Keep going as quotas, blockers, and the clock grow tougher from shift to shift. DESIGNED FOR TOUCH Draw with one finger and drag backward to erase. Start the conveyor whenever you are ready, watch the parcels move, then adjust your line and try again. Solver-backed hints can give you a nudge without solving the whole board for you. MADE FOR QUICK BREAKS AND THOUGHTFUL REPLAYS - Save campaign progress, best times, routes, and stamps on your device - Play the core game offline; an internet connection is used for ads - Adjust larger text, reduced motion, high contrast, music, sound effects, and haptics - Play in English, German, Spanish, French, Italian, Brazilian Portuguese, Russian, Japanese, Korean, or Simplified Chinese One-Line Factory is free and supported by ads.

Shadow Grid is a calm, satisfying 3D puzzle: stack and rotate simple blocks on a grid until the shadows they cast on two walls match the target silhouette exactly. - 200 handcrafted levels, from a gentle two-piece start to real spatial-reasoning challenges. - A separate 100-level Pro pack for players who want a tougher challenge - bigger grids, more pieces, and blocks that sit at different heights so the shadows overlap in ways you can't just read off the floor. - Drag pieces along the floor and tap to rotate - no timers, no penalties, just figure it out at your own pace. - Global leaderboard: pick a username and an avatar, and see how your progress compares to other players. - Five visual skins to re-color your blocks, from a classic monochrome look to warmer palettes. - Reset any level instantly and try again as many times as you like. No sign-up required - just open the app and start stacking. An optional one-time purchase removes ads entirely.

Verdict
The clearest difference is in-app purchases: One at none against ShadowGrid's 2. One also leads on iOS requirement (15.0 vs 17.0). On price, ads and device support there is nothing between them.
