Oskar's collection

All puzzles featured on this page have been developed, or co-developed, by puzzle designer extraordinaire Oskar van Deventer of the Netherlands. Ever wondered what a 4D maze might look like? Or how your alter-ego might feel if trapped in a parallel-universe maze? Well now you can find out.

Update June 2009: Oskar is now presenting many of his latest and greatest mechanical inventions on YouTube.

In 2007 Oskar's Triangler game (a collaborative geometric outdoor mobile interactive game for mobile phone) recently won two of the presigious IMG Awards! Grand Prix and Most Innovative. See The IMGA 2006 winners and IMGA 2006 Nominees -Triangler
