Mastermind: A sequence of four coloured pegs sit behind screen at the end of the board. The player has 9 attempts to guess the correct combination.

The player makes a guess by dragging four pegs from the rack into each of the holes in the board. The guess may be submitted for marking by clicking on the blueish disk to the right of the board. Marks are awarded as follows:

  • A black mark is awarded of the right colour is in the right place
  • A white mark is awarded if the right colour is on the board but in the wrong position.
Cubes Puzzle: Each row or column of cubes may be rotated either clockwise or anti-clockwise by clicking on one of the smaller spheres. The larger sphere will scramble the cubes - your job is to put them back so that they are all facing the same way. 7
Tower of Hanoi:

Each disk is seated on a peg. No disk may be placed on a smaller disk. The tower on the leftmost peg must be transported to the rightmost peg.


Grand Mastermind In this version there are six possible colours and six possible shapes giving a total of 36 possible "pegs". Black and white marks are awarded as above - in addition a blue mark may be awarded if either a colour or a shape is in the right place.
  • A black mark is awarded of the right colour and shape combination is in the right place.
  • A white mark is awarded of the right colour and shape combination is in the wrong place.
  • A blue mark is awarded where the right shape with the wrong colour, or the wrong shape with the right colour is in the right place.

Note that once a guess peg or a hidden peg has contributed to a black or a white mark it does not contribute to a blue mark.
