Top tip! Test your knowledge of Dutch geography with this free game

Tijmen Klein, a 38-year-old developer, has created a free daily geography game called Polderprikker to test users' knowledge of the Netherlands. The game was initially developed for friends to fill a gap in the market for Dutch-focused topographical puzzles, but it has since grown to attract between 2,500 and 3,000 daily active players. Participants must accurately pinpoint five locations on a map each day, ranging from major cities like Haarlem to smaller towns, castles, and landmarks.

The challenge is intensified by the use of satellite imagery, which lacks traditional political borders and clear infrastructure markings, forcing players to develop a better spatial understanding of the country. Klein intends for the game to remain a fun, brief activity, though he has occasionally introduced thematic editions such as one honoring the Gronings Ontzet. With some dedicated fans having played for over seventy consecutive days, the game has become a successful, community-driven project that continues to evolve with new potential themed iterations.
