60m more users available to the Japanese connected gaming service.
London-based Mind Candy has enjoyed huge success with its family-friendly games brand Moshi Monsters, and clearly see this move as a means to expand its community.
GREE has 230 million worldwide users on a network that delivers community features like messaging, leader boards and micropayments.
The partnership will deliver two as yet unnamed new games, and will also expand upon Moshi Monster's global footprint by delivering localised games in English, French, Italian, German, Spanish, Portuguese, Japanese, Korean, Mandarin and more.
"Our fans love tablets and smartphones so we're really excited to take our much loved characters and stories to these new platforms," said Michael Acton Smith, Founder and CEO of Mind Candy.
"GREE has achieved phenomenal success, and we're looking forward to working with them on these two games."
Good news for GREE, which could do with some right now. Its business is under significant pressure across Asia following a landmark decision to better regulate the practice of selling virtual items.
In May, Japan state officials implemented a ban certain microtransaction techniques in social games, in a move that saw GREE's share price fall dramatically.
