7 Simul Intro

If you don't know how to solve Rubik's Clock using the Flip Method, please read Stefan Pochmann's website.
Flip method is a very good method and can already help you achieve world class.
But most top clock solvers use the so-called 7 simul method.
The most popular 7 simul variant is Tommy's version, which requires using pinky finger for bottom dials.

Method

In 7 simul, we use a fixed pin order to solve the clock.

Then we memorize 6 numbers based on modulo arithmetics of 12 (e.g. 5 = -7, 3 + 8 = 11 = -1, 5 + 8 = 13 = 1, 2 - 3 = -1, 2 - 8 = -6 = 6).
You will have the flexibility on how to memorize them. But we recommend several common strategies:

1. Remember numbers as-is in your native language.
2. Encode numbers into A for 1, B for 2, ..., K for 11.
3. Combine both, e.g. 1-6 with native language, and E for 7, D for 8, etc.
4. Similarly, but instead of native language, use a language (e.g. Japanese/Korean/Chinese) which has low syllabus count for numbers.

After memorizing these 6 numbers, we will solve the clock with the aforementioned pin order.
Each time, you will adjust two dials simultaneously (unless the adjustment required is 0), either based on the memorized number, or based on intuitively matching two clock faces (similar to flip method).

The best way to illustrate this method is to use a demo example.

Now the clock is solved!
