Sindokus: Sudoku with different worlds

In Sindokus you solve a logic grid using Sudoku rules. You choose the type of field: numbers, large details or portraits, and then fill in the cells.

How to start solving a mesh

  1. Choose a world: Wild-oku, Cat-oku, Plants-oku or Su-Dog-ku.
  2. Choose the type of field: numbers, details or portraits.
  3. Click or tap a cell, then select a number or picture.
  4. Fill each row, column and 3x3 block with one character.

How do worlds and field types differ?

In Wild-oku you read animals by their skin and faces, in Cat-oku - cats by poses and breeds, in Plants-oku - plants by leaves and flowers, and in Su-Dog-ku - dogs by things and puppies. A grid with symbols and 3x3 blocks - familiar from Sudoku Classic.

When to enable Extreme mode

In Extreme mode, each block mixes all three types at once. Then there are numbers, details and portraits in one grid, and you need to check them as one set of symbols.

  • Mouse - select cell and symbol
