Just a quick note, it’s not 2.85% but 1/(36-9) = 1/27 ≈ 0.037 = 3.7%.

As a fun fact, larger boards like that were possible to create on that site (e.g. 30x30 with 898 mines) and some even had wins. Now I can’t even search for them in “ranking”.

The sad part is potentially losing all the information, communities, etc. You can pretty much expect any company to go bad, so it makes no sense to get attached to a company.
