Tetris Effect: the gift that keeps on giving. During this weekend’s Ritual Event – which essentially sees the community working together to clear lines and win in-game prizes – players noticed that upon completion a Mystery stage had been added to the release’s arcade Effect Mode. The level? It’s only bloody well inspired by the original Game Boy game. And it’s freakin’ brilliant.

While many people have now lost access to the stage, you can apparently unlock it by reaching Level 50, which is incentive enough to keep playing. It’s left us pondering what else is hidden in this title, though. A hidden Wetrix stage perhaps? A secret mode inspired by The New Tetris? The mind boggles at the possibilities, doesn’t it?
