What is the Roux second block?

The second block is step two of the Roux method: a 1x2x3 block on the right, built opposite the first. Its last pair goes in much like an F2L pair, but with the front and back edges free. There are 65 second-block cases.

If you already know intuitive F2L, many of these cases will feel familiar. Drill the ones that do not.

Frequently asked questions

How do I practice Second Block algorithms?
Pick which cases to drill, then one of three modes: Flashcard (see the case, recall the algorithm), Virtual Cube (solve on a 3D cube with a Bluetooth smart cube or your keyboard) or Scramble (set the case up on your own cube and solve it). The trainer serves the cases you are still learning, the ones you fail and the slow ones more often than the ones you already know.
How does the trainer know which Second Block cases I know?
From the status you give each algorithm in the Second Block database: Not known, Failing, Learning, Getting there or Muscle Memory. Filter the drill by status to practice only the cases you are learning, and update a status as it changes.
Do I need a smart cube?
No. Flashcard and Scramble work with any cube, and Virtual Cube mode also takes keyboard input. A Bluetooth smart cube lets Virtual Cube mode follow your turns on a real cube.
