Combiku™ rules are very simple.

  • You are given a 5x5 board which contains some Shapes and Colors on it.
  • Use the mouse to drag other Shapes or Colors from the sides into the board squares.
  • Your objective is to place one Shape and one Color in each square.
    • Two squares cannot have the same combination Shape-Color.
    • And a Shape (or Color) cannot be repeated in the same column (or row).
  • You may prefer to use Numbers and Letters instead of Shapes and Colors.

Don't hesitate to use the following features:

  • Save a puzzle to resume it later.
  • Let the computer play for you and explain the move.
  • Undo-Redo your movements.
  • Display little notes on each square to keep track of your own conclusions.
  • Switch between "Numbers and Letters" and "Shapes and Colors".
  • Highlight the first square with a mistake with respect to the puzzle solution.
