As a maker of jigsaw puzzles, Heye established itself worldwide as a supplier of high-quality products with original and innovative designs. Heye originally focused on humour and cartoons but over time developed a comprehensive product range featuring a variety of formats and topics. Some of the products quickly became bestsellers, and renowned international artists like Mordillo, Hugo Prades, Marino Degano, Rosina Wachtmeister or Victoria Francés became long-time partners.
