The third GRiddles series is now live, with a new set of increasingly challenging puzzles to take on. Series B is nearly complete, but there’s still time to tackle the final puzzle, with an extended deadline and £3,000 up for grabs. Series A is now closed, but you can still explore the original puzzles and take on the challenge.
Welcome to GRiddles
At G-Research, puzzles have a habit of appearing everywhere. GRiddles is a competition inspired by that culture. If you enjoy getting stuck, thinking sideways and coming back for another go, you’ll probably feel at home here.
