How to play
- Fill the grid so every row, column and thick-edged region holds each of the nine animals once.
- The regions are curved shapes, not the usual boxes. Their edges are drawn thicker.
- Tap a cell, then an animal. Notes mode lets you pencil in candidates. Conflicts show in red as you play.
- Pick Daily for today's puzzle, the same for everyone, or Easy and Hard for fresh ones. Your time is saved when you finish.
Controls: mouse, touch or keyboard. Made by CalcoTools.
Tips and strategy
- Count the animals in a region first. Regions with many animals already have the fewest choices.
- Look along the long, thin regions. They cross many rows and columns.
- If an animal can only go in one row of a region, it cannot go anywhere else in that row.
- Use notes in cells with two or three candidates and clear them as animals are placed.
FAQ
- Is it the same as Sudoku?
- Yes. The animals stand for 1 to 9, and the regions are curved like in Jigsaw Sudoku.
- Do I have to use the animals?
- The keypad and the grid both show the animals, and the keyboard keys 1 to 9 place the same ones in order.
- Is the daily the same for everyone?
- Yes, on the same UTC day.
