If you love a daily logic puzzle that rewards deduction over luck, Parcel sits in great company alongside Sudoku and Shikaku. Here's how they differ — and why Parcel is worth adding to your routine.
Sudoku: numbers and constraints
Sudoku is about placing digits so rows, columns and boxes each hold 1–9 once. It's pure constraint-satisfaction — no spatial reasoning, just careful elimination across a fixed grid.
Shikaku: dividing into rectangles
Shikaku asks you to split a grid into rectangles, each containing one number equal to its area. It adds spatial thinking — you're reasoning about how shapes pack together, not just which digit goes where.
Parcel: area plus shape
Parcel takes Shikaku's tiling idea and adds an orientation clue to every box — wide, tall, square or any. That extra hint makes the opening more approachable while keeping the satisfying packing logic intact.
- Sudoku — constraint logic, no geometry
- Shikaku — rectangle tiling by area
- Parcel — tiling by area and shape, with a daily puzzle and stats
Which should you play?
Play Sudoku for pure number logic, Shikaku for spatial deduction, and Parcel when you want both in a quick daily hit with a streak to protect. Many puzzlers happily do all three.
