French book publisher Hachette Livre today announced that it has entered in to exclusive negotiations for the purchase of Gigamic from founders Jean-Christophe Gires and Stéphane Gires. Gigamic, also based in France, publishes a variety of strategy and family games, with its best-known titles probably being Quarto and Quoridor.

For Hachette Livre, which already publishes party games (quiz games, etc.), and which added mobile games to its portfolio in 2016, this investment is part of a strategic decision to explore the leisure activity market that sits alongside publishing, in particular all the segments of the consumer gaming market.

Stéphane Gires will continue to manage Gigamic after the transaction closes.

According to the Hachette Livre announcement, Gigamic’s annual sales exceed €15 million.
