This website is a tool for drilling commutators and algorithms for blindsolving. Instead of relying on seeing cases in real solves, you select specific cases you want to practice. This way you can effectively and efficiently practice all cases, but especially the rare or difficult ones. The proper use of this website will significantly decrease your recall speed and make you more confident

To sync data between device, just open the sync popup on the landing page and click "export" to export your local data to a database, or "import" to import it back to your device.
Your data will be stored together with a unique ID, which is automatically generated and displayed in the same popup. However you can change it, which is used to have the same ID on two different devices. Once you have the same ID saved on all the devices you will use, you will only have to click import or export.

A preset is a way to store selected pieces, usually ones you practice often.
Select all the cases you want to store and click "set" next to the preset you want to store the cases in. When you want to practice these cases, simply click the preset you stored them in and the case will be selected for you. You can double click the preset to change its name and click reset to delete the cases stored inside it.
Presets are stored in your browser's local storage, as well as in a database if you have an account.

A slow preset is a collection of your slowest cases based on your practice sessions. It is individually stored for each category and each floating buffer and is automatically updated after each practice session.
In the settings, you can adjust the maximum amount of cases stored as well as the maximum time a case can have in order to be stored. Limiting this time is useful, because it prevents the website from storing cases that have a high time due to being away from your device for example. You can reset all slow presets in the main settings.

In the main settings, there are 2 input fields. The first one, saying "Corner scheme here", is for the corner scheme and the second one, "Edge scheme here", is for the edge scheme.
Corner scheme is used for: Corners, Twists, parts of Parity, LTCT, Words, Xcenters
Edge scheme is used for: Edges, parts of Parity, Wings, Midges, +centers
Enter your 24 letters without spaces in the 2 fields and click "Save". The order in which you must input them is important. The order is A to X according to the speffz scheme, which is:
Corners: UBL UBR UFR UFL LUB LUF LDF LDB FUL FUR FDR FDL RUF RUB RDB RFD BUR BUL BDL BDR DFL DFR DBR DBL
Edges: UB UR UF UL LU LF LD LB FU FR FD FL RU RB RD RF BU BL BD BR DF DR DB DL

You can change your buffer by opening the piecetype settings and double clicking whatever buffer you want to practice. You can rearrange them to your preferred order with drag-and-drop.

"Cases before break" -> This is how many cases you will be shown before a break. 0 means no breaks.
"Target time" -> The time (in seconds) that you want each case to be under. Cases that were above the target time can be practiced again after each session.
"Amount of cases" -> The maximum amount of cases you want to have saved in the slow presets.
"Max time" -> The slowest time (in seconds) allowed to put into the slow cases. This can be used to prevent cases from being stored when the time was high for external reasons, eg. you had to leave your device.
"Include inverse cases" -> Selecting this will include the inverses of the cases you selected, eg. selecting AG will also include GA for the practice session.
"Show next letterpair" -> This feature shows the next letterpair (or case) under the current one. This can be used to more accurately simulate real solves, where you know the next letterpair while executing the current one.

On smaller devices, the chart with all your times will not be shown due to lack of horizontal space.
