lighthouse score rank for some pwa that I like !

Pwa ranking according to the lighthouse score. Lighthouse is the the tool present in google chrome to audit web apps.

The score here is computed with this formula : 10*pwa + 4*performance + 3*accessibility + 2*best-practices + 1*seo and in case of equality, time for first paint makes the difference

I did set a tolerance for performance for two reasons:
1°) lighthouse is a little inconstant when you exceed a score of 95.
2°) in the case of a pwa, the first loading can be a little slow but the following ones are very fast.
As a result, a score >= 95 is considered to be equal to 100.

The php source file that produces this list is here : https://github.com/hugues-koolsol/lighthouse

The pwas on the top of the list below have a 100 for all lighthouse scores : pwa, performance, accessibility, best-practice and seo . It is not very easy to get a 100 for all these scores but some can reach this challenge 💪 :-)

I like solitaire game so you will find many of them in the list below.

I did koolsol because I wanted a fast and simple solitaire card game with solutions for the players around the world with translations in 27 languages. I am disapointed by the rank Google gives to it because I applied all the requirements ( pwa, offline and online, fast ...) and it is far from being on the first page when one search for solitaire game. Why ?
