What is CubeDB (cubedb.net)?

Updated

CubeDB is a browser-based tool for speedcubers and puzzle solvers, built around algorithm practice, scramble playback, and solve analysis. It is not a general-purpose course platform despite the "educational resource" framing on its landing page; the actual interface is a cube simulator and timer workspace. If you want to drill algorithms, reconstruct solves, or compare move counts across notation systems, it is aimed at you. If you are looking for structured lessons or video courses, the site itself does not appear to host that content.

What the site actually provides

The working area is a virtual puzzle with a move log, a timer, and a playback control. From the page evidence, the core functions are:

  • Puzzle support: 3x3, 2x2, 4x4, 5x5, 6x6, 7x7, Square-1, Pyraminx, Skewb, and Clock.
  • Highlighting modes: Full, Cross, F2L, OLL, PLL, COLL, F2B, CMLL, Centers, Edges — so you can isolate the stage you are practicing.
  • Color and block filters: Cross color (White, Yellow, Green, Blue, Red, Orange) and Roux block pairs (Blue/Green, Red/Orange, Yellow/White).
  • Face controls: U, D, F, B, L, R faces with reset options for colors and faces.
  • Move metrics: HTM, QTM, STM, ETM counters.
  • Transformations: Rotate(x/y/z), Mirror(M), Mirror(S), Dual, Invert, Remove Comments.
  • Algorithm playback: a "Moves Algorithm Playback" control with a result field in seconds.
  • Automated Solve Critique (CFOP) and an option to toggle old notation (r = 2R).

Who it is for

Three groups get the most out of it:

  1. CFOP solvers — the automated critique and F2L/OLL/PLL highlighting map directly onto that method.
  2. Roux solvers — the F2B, CMLL, and block-color filters are Roux-specific, which is unusual for a general cube tool.
  3. Method-agnostic analysts — the metric counters and notation toggles suit anyone reconstructing or comparing solves.

Practical notes

  • There is a WCA Login entry point, which suggests account-based features tied to competition identity, though the page evidence does not specify what the login unlocks.
  • The site is credited to Gil Zussman.
  • A donate link is present, but no pricing page or payment platform is listed, so there is no evidence either way about paid tiers.
  • The "New Recon" label next to the author credit implies a reconstruction feature, consistent with the playback and critique tools.

How to use it for a practice session

  1. Pick your puzzle from the size/type row.
  2. Set highlighting to the stage you are drilling (for example, PLL only).
  3. Enter or generate a scramble, then use Playback to step through the solution.
  4. Read the HTM/QTM/STM/ETM counters to compare efficiency between attempts.
  5. Run Automated Solve Critique (CFOP) if you solve CFOP and want stage-level feedback.

The main limitation to expect: this is a solver's utility, not a curriculum. There are no lessons, no progress tracking described in the page evidence, and no stated pricing model. Treat it as a practice and analysis bench rather than a course.
