Jonathon Blow reckons that his gorgeous new PlayStation 4 puzzler The Witness is going to take you a healthy chunk of time to fully complete. Indeed, speaking on Twitter, Blow said that a play-tester took approximately eight days to beat the game. He then did some complicated maths and determined that this means that the title will probably take you around 70 hours to 100 per cent.

What's more, the provocateur is claiming that these 70 hours will be filled with original content. "This is in a game with no repetition or filler," he said. "Everything that you solve is different and has its own reason for being there." Well, thank goodness.

Rest assured that we've ordered our crack team of mathematical monkeys to double check the auteur's figures, and will bring you the findings as soon as possible. In the meantime, give us your thoughts on The Witness in the comments section below.
