Oginov Tumbler is a game from Drumond Park that's designed for children aged 8 and over. Invented by the mathematics professor, Dr Pantazis Houlis, the game operates on a gravity/tilt system whereby pyramids must be tumbled into a certain sequence with the use of a transparent rotating ball. The game challenges your spatial awareness and is also useful for developing numeracy skills.

The Oginov Tumbler Starter Set features two different games: The Dots and The Colours. The beauty of both games is that players can choose how hard they want them to be. Being able to affect the level of challenge of the game means the possibilities are endless. For example, you may like to introduce a time-limit to the game or come up with a handicap system if there's a large age-gap between the players.
