Puzzles by Designer > Oskar van Deventer

Oskar lives in the Netherlands and is a telecommunications research engineer who started designing puzzles in 1978 and has since designed some hundreds of different mechanical puzzles not least of which are the wonderful take apart type puzzles he's designed for Hanayama in recent years. 

	H & H cast puzzle designed by Oskar	QTY:
	Difficulty Level 5 The puzzles is to try to separate the two H's that are locked together. As the name suggests this cast metal puzzle consists of two pieces shaped like the letter H.

	Anti Virus - The Bio-logical puzzle game	QTY:
	Ages 7+ (loved by Adults!) Multi-level Logic Game.  Develops strategic planning, visual and spatial perception.  60 Challenges.  5 levels.  Starter, Junior, Expert and Master. Put your immune system to work and get rid of the virus before it can multiply itself. Anti-virus is a sliding puzzle game with a new twist. Tiles that only slide diagonally and can move in groups!  Once you "catch the bug" it's hard to put this game down. Playing this game is a very tactile experience;  the tile pieces are moulded such that they 'fit' your fingers very well.   They also fit the game board which is moulded so the pieces fit exactly and force the diagonal moves.  A quite addictive puzzle.

	Marble - Cast Puzzle designed by Oskar	QTY:
	Difficulty Level 4 This puzzle has such a beautiful shape that it could easily be mistaken for a piece of jewelry. Its surface features extremely unusual cuts; actually, this marble is a puzzle that can be broken up into 4 pieces. This advanced design is the creation of Bram Cohen & Oskar van Deventner. If you succeed in breaking up the marble, carefully examine the surface of the sections of each piece. The theme of this puzzle is "Sphere."

	Chain - Japanese Cast Puzzle	QTY:
	Difficulty Level 6 Can you separate the three links of the chain and then get it back together again? What's special about this puzzle is that it can be solved three different ways, depending on which of the three pieces has been chosen as the middle link.

	Duet - Cast Disentanglement Puzzle	QTY:
	Difficulty Level 5 At first glance it looks like there is only one ring hanging from the grid but there are in fact two rings attached with a magnetic force. Can you separate the rings from the grid and return them to their original positions?

	Equa - Cast Take Apart Puzzle	QTY:
	Difficulty Level 5 The object of this brilliant cast metal puzzle is to take the two interlocked loops apart and take them out of the surrounding planet like structure, then get the puzzle back together again.  The puzzle was designed for Hanayama by Oskar van Deventner of The Netherlands and released in 2008.

	Nut Case - Cast Puzzle	QTY:
	Difficulty Level 6 There are two goals to the Cast Nutcase created by the Dutch puzzle inventor, Oskar van Deventner. 1. Remove the small nut by disassembling the Cast Nutcase. 2. Cast puzzle enthusiasts (some call them nutcases) can enjoy trying to change the wording on the bolt from "nut-case" to "case-nut".

	SOLD OUT 2 IN 1 - 12 piece interlocking burr	N/A
	Oskar van Deventer (inventor of Oskar’s Cube) designed this puzzle in Holland in 1985. He nearly always designs his puzzles in his head before completing detailed drawings for craftsmen to work from. He usually never makes the finished product himself. This puzzle was originally made with 12 aluminium pieces but here MR PUZZLE has created a beautiful wooden version from Queensland Silver Ash. The unusual pattern in which the 4 x 4 x 4 pieces are offset makes it an extremely difficult puzzle.
