Some cool finger tricks. Don't leave your finger from the cube most of the time.
More nice exercices to do (RUR'U', L'U'LU, RUR'F...)
Video on how to move F2L to FR column.
  • Cube rotation: y U' L' U L. Quite slow.
  • Sledgehammer: F R' F' R.
    A bit faster, no cube rotation. Use it for inserting your last f2l pair for partial edge control of your OLL, or to avoid moving your next pair if you've spotted it using look ahead. Apparently the F' is done with the thumb, a bit before doing the R.
  • Case Number 2: F' (r U r')
  • Case Number 3: r' U' R U M'
  • Case Number 4: l U L' U' M'
Solutions
Shops
Sell the recommended lube lubix's lube, but oversee, so high shipping and custom cost.
Sell Maru lube (not recommended, see below), Calvin's lube high viscosity and Calvin's lube medium viscosity (seems very good).
Sell Zhanchi's cube, but not black ones.
Tools

Apps

Android

Games
A rubik's cube game. A bit though to manipulate.
Timers
A simple speedcubing timer with scrambler algorithms support. Very nice design, all on one single page. Best out there.
A timer for speed cubing. Some ads and no much features.
A timer for speed cubing. Scramble algorithm. No graph.
A timer for speed cubing. Scrambe algorithm. No graph. Compare cube brands. Too many pages.
A timer for speed cubing. Scramble algorithm. Graph. Design not as good as Rubik's Stopwatch. Additional resources like algo, WCA regulations.

A simple, elegant timer with WCA scrambles for recording Rubik's cube solves. Graph and history by session (best, best AO5), scramble image, double touch inspection.

Solvers, Algorithm database
Solver (manual input or via camera). List of solving algorithms.
A big database of all possible sequence for each category (PLL, OLL, F2L...). Support for 'favorite' flag, adding new category and new algorithms.
Simply a big page with all solving algorithms, clear and well-designed. Must have.

PC

  • TNoodle
  • Official WCA's scrambler, showing final cube state. Include a very nice timer application. Download TNoodle:
    git clone https://github.com/cubing/tnoodle.git
    
    ./tmt graph --description                 # To get a list of available target
    
    Timer
    Timer application is only available up to v0.8.7.
    git checkout v0.8.7
    ./tmt make dist timer
    sudo cp -r timer/dist /usr/local/bin/tnoodle-timer
    chromium-browser /usr/local/bin/tnoodle-timer/tnt.html           # To start the javascript timer
    

    In old version, timer is available as a .jar file. For instance:

    git checkout v0.7.14
    vi tmt
    # Comment line with
    #                args += [ '-Werror' ]
    ./tmt make dist timer
    java -jar timer/dist/TNoodleTimer.jar 
    # Then visit http://127.0.0.1:8080/tnt/ or http://127.0.1.1:8080/tnt/ (or possibly port 2014)
    
    • Data for the javascript tnoodle-timer is stored in chromium local storage:
    ~/.config/chromium/Default/Local Storage
      __0.localstorage
      __0.localstorage-journal
      chrome-extension_pafkbggdmjlpgkdkcbjmhmfcdpncadgh_0.localstorage
      chrome-extension_pafkbggdmjlpgkdkcbjmhmfcdpncadgh_0.localstorage-journal
    
    Or better, in chromium, open developer tools by pressing F12, go to Resources tab. Timing data are stored in Local Storage → web site → variable sessions.
    • To install tnt in lighttpd (example on lacie-cloudbox):
    vi /etc/lighttpd/lighttpd.conf
    
    Add the lines
    ## Added for rubik's WCA official scrambler / timer
    alias.url += ("/tnt" => "/opt/local/tnoodle-timer/tnt.html" )
    
    Copy all files to /opt/local/tnoodle-timer/
    Then open browser at http://lacie-cloudbox/tnt/ (Firefox or chromium works best it seems)
    Other TNoodle apps
    • BLD
    • scrambler
  • qqtimer (the most used timer it seems) (qqTimer on GitHub)

Solution

We use notations from https://github.com/chrishunt/rubiks-cube:

  • R, means turn Right face clockwise
  • R' or r, means turn Right face counter-clockwise
  • R2, means turn Right face twice.
Swap 2 edges
